Measures to prevent accidental flooding

Before explaining how to use the many features of the D-180 we recommend first understanding some essential practices that will greatly reduce the main causes of accidentally flooding the

D-180. The D-180 is waterproof due to a rubber O-ring that seals the internal circuitry from the elements. There is only one user serviceable O-ring: the Battery Box O-ring. This O-ring requires frequent inspection and care to ensure its watertight integrity. Since most flooding occurs due an O-ring related problem we strongly recommend you to inspect the O-ring (and clean, grease or replace as necessary) each time before using the strobe. Equally important are O-ring contact surfaces. Check the contact surfaces for contaminants or scratches. We cannot stress enough the importance of making O-ring related inspection and maintenance a habit and essential part of your pre-dive equipment preparation routine.

O-Ring inspection locations

Inspect and maintain these three points:

Battery Box O-ring

Battery Box O-ring groove

Battery Box outer cap O-ring contact surface

O-ring inspection methods

These are the essential factors to ensure proper O-ring function:

The O-ring itself

O-ring contact surfaces

O-ring grooves

If O-ring is properly seated in groove

Grease

INON D-180 Manual

Version 1. October 4, 2003

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

First, inspect the O-ring as it is seated in the groove. If any of the following are evident, there is a high chance that the strobe will flood if placed in water. Be very careful about checking these points:

If hair, sand, lint or other debris is attached to the O-ring

Remove O-ring and wipe-off the debris.

If the O-ring is cut or cracked

The O-ring must be removed and replaced with a new O-ring.

If the O-ring is twisted

The O-ring must be removed and reinstalled uniformly with no twists or other irregularities.

If there is hair, sand, lint or other debris on the O-ring contact surfaces

Wipe of any debris.

If there is a scratch, blemish or other imperfection on the O-ring contact surfaces

The strobe must be inspected by an authorized technician, and repaired if possible.

Contact Inon or you local Inon distributor for advice.

O-ring Maintenance Method

Grease: Inon O-rings are compounded with a special type of oil that is not compatible with all grease types. Periodically re-grease the

O-rings only using the supplied Inon Grease. Do not use any other grease, which may cause the O-rings to swell or deform, causing poor seal and water leakage. Use of non-Inon grease will void warranty.

Field Maintenance: For periodic maintenance in the field it is not necessary to always remove the O-ring and inspect the O-ring groove for each dive. If there is not any sand or other debris visible it is ok to lightly grease the O-ring while it is seated in the O-ring groove.

For other maintenance follow the instructions below.

Removing O-ring

If you need to remove the O-ring for replacement, inspection, or to check the O-ring groove etc., lightly squeeze the O-ring from the sides

(see figure) so it bulges out from one side. Grasp the extended part and gently pull to remove. Never use sharp or metal objects to

remove O-rings as they may damage the O-ring itself or the O-ring

groove contact surface. If squeezing the O-ring from both sides does not work, try gently using the edge of a credit card or similar object, to pry the O-ring up a little so you can grasp it. Then clean any residual grease or debris from the O-ring groove and contact surface, and check the condition

INON D-180 Manual

Version 1. October 4, 2003

of both surfaces. Wipe off the O-ring and determine is if is still useable or not.

Installing O-ring

After checking and confirming that the O-ring groove is clean and not damaged, using your fingertips, apply a thin uniform film of Inon grease on the O-ring. Install the O-ring in the groove, making sure that it is seated uniformly and not twisted. Then add a little extra grease to the O-ring, and liberally grease O-ring contact surface on the battery box. A little extra

grease is necessary due to friction when screwing down the battery box cap. Slowly screw down the battery box cap, making sure you don’t feel any excessive resistance, which could mean the O-ring is binding or bearing too much friction.

When the battery box cap is fully screwed down and seated on the O-ring surface, look at the

O-ring through the transparent edge of the cap. You should see a continuous, uniform contact line (the “witness line”) between the cap and O-ring. If the contact line is not uniform, or twisted, contaminated with hair, lint or sand etc. there is a good chance the strobe will flood.

Remove cap, re-seat O-ring and/or remove contaminants as necessary.

Chapter 1 D-180 Features

D-180 Main Functions

The D-180 is a high performance, multi-function underwater auto-strobe, designed to be particularly useful with digital camera systems and including features such as advanced cancel circuitry and an integral underwater light. Depending on what camera system and master strobe the D-180 is used with, the useable D-180 functions will be different. Some functions are only useable in conjunction with certain camera and strobe systems.

The main functions are:

1) Flash Function

(External Auto Strobe / External Auto Function)

When camera shutter is released the D-180 flashes in time with the camera and automatically adjusts flash output for correct exposure.

Using the D-180’s “External Auto Flash Exposure Adjustment” (hereafter, “External

Auto”) control mode the D-180 itself automatically adjusts for correct flash output amount and “proper” exposure. It is not necessary to rely on the camera’s automatic flash adjustment control. Or use the Manual Mode 4 step flash output adjustment for manual strobe control.

2) Slave Strobe

(External Auto Slave Strobe Function)

When connected to another (master) strobe, including internal strobes of digital cameras, the D-180 flashes at the same time as the master strobe.

Using the D-180’s “External Auto” control mode the D-180 itself automatically adjusts for correct flash output amount and “proper” exposure. It is not necessary to rely on the camera’s automatic flash adjustment control. Or use the Manual Mode 4 step flash output adjustment for manual strobe control.

3) Advanced Cancel Circuitry

For digital cameras which emit a “pre-flash”, compared to conventional strobes with simple pre-flash cancel circuits which cause the camera’s internal strobe to emit a full discharge on the second main flash, the D-180 Advanced Cancel Circuit effectively reduces the main flash output with the following benefits:

- Conserves the internal strobe’s condenser energy so the internal strobe’s recycle time is shortened, allowing quicker follow-up shots.

- Reduces energy consumption so more images can be taken per set of batteries.

4) “Clear Photo System” Compatible

“Clear Photo System” allows the external strobe (D-180) to be more effectively used

INON D-180 Manual

Version 1. October 4, 2003

12

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

as a Slave Strobe, by reducing the amount of backscatter caused by light coming from the camera’s internal strobe illuminating suspended particles in front of the lens, enabling clearer, higher quality images.

The system

(Patent Pending) was devised from the D-180’s design conception. First, a

“Clear Photo Filter” is placed over the camera’s flash. This filter blocks visible light, only allowing non-visible wavelengths to pass though. Accordingly, there is no visible light to illuminate the particles in front of the lens. The non-visible light is picked up by a fiber optic cable and relayed to the strobe, triggering a flash output.

Clear Photo Film is included with Inon “Optical D Cable/Cap Sets” available for various camera/housing systems.

5) Shutter Linked Auto-Off Focus and Target Light

The Focus and Target Light has many functions. First it shines light on the subject, increasing contrast so both Manual and Auto Focusing are easier. Also, it helps aim the strobe’s beam axis directly on the subject. Upon activating the Focus Light

Switch, the Focus Light will turn on, and upon sensing the camera’s internal strobe flash, will automatically turn off so no light from the Focus Light is recorded in the image. Also the Focus Light can be set to turn off automatically in about eight seconds if the Focus Light Switch is not pressed again.

Reference No. 1 Automatic Flash Adjustment of External Strobes

When using external strobes, in order to automatically adjust the amount of flash output and properly expose the subject, it is necessary to calculate and control the strobe’s flash duration (light output amount / “intensity”) using the following information.

ISO sensitivity

Aperture Value

Reflectivity of the subject

Of this information, depending on the method of measurement and part of the subject being measured for reflectivity, the methods of automatic flash output adjustment can be classified as follows:

1) During exposure, the camera meters (measures) in real time

Subject reflectivity measured TTL (Through The camera’s Lens) in real time; strobe quenches

(turns off) at time of “proper” exposure. (Real Time TTL Auto Exposure Adjustment)

Using a light sensor on the camera, subject reflectivity is measured in real time; strobe quenches at time of “proper” exposure. (Real Time Auto Exposure Adjustment)

2) Before exposure, camera meters (measures) a “pre-flash”

Camera’s internal strobe fires a small “pre-flash” to illuminate the subject. During pre-flash,

INON D-180 Manual

Version 1. October 4, 2003

subject reflectivity measured TTL; based on this information, second (main) flash duration is calculated, and then strobe fires main flash quickly afterwards, only for the specified duration.

(Pre-flash TTL Auto Exposure Adjustment)

3) During exposure, strobe itself measures in real time

Using a light sensor in the strobe, subject reflectivity measured in real time, with strobe quenching at time of “proper” exposure. (External Auto Flash Exposure Adjustment)

For each of these automatic flash adjustment methods to work, besides a signal instructing the external strobe to fire, the various combinations of cameras (and master strobes) and external strobes must be compatible with each other’s signal transmission methods.

Aperture Value information

As of December 2002, a majority of consumer digital cameras use Pre-Flash TTL Auto Exposure

Adjustment. Unlike conventional 35mm film camera systems with the widely adopted Real Time

TTL Auto Flash Adjustment, most current digicams cannot use such automatic exposure adjustment with external strobes. Likewise, except for some dedicated land strobes for certain camera brands, there are no external strobes yet available fully compatible of functioning with the various Pre-Flash TTL Auto Exposure Adjustment type cameras available. The main reasons are:

Because pre-flash specifications and protocol have not been standardized between the camera manufacturers.

The external strobe to camera signal transmission specifications have not been standardized between camera manufacturers, and the communication method used by most existing external strobes has not been adopted in most digital cameras.

Due to the lack of real time information from camera to strobe, digital cameras cannot automatically adjust exposure with external strobes. Therefore it is necessary for the external strobe itself, to a certain extent, independently execute automatic flash adjustment.

The D-180, as an External Auto Flash Exposure Adjustment type of strobe, and using an Advanced

Cancel Circuit, is compatible with the vast majority of digital cameras using Pre-Flash TTL Auto

Exposure Adjustment, and of course Real Time Auto Exposure Adjustment type cameras.

Regardless of the camera type, automatic light adjustment is possible with the D-180 external

strobe itself.

To determine your camera’s automatic light adjustment type please refer to your camera manual, and Page 18, “Items to confirm before using D-180”.

Flash Adjustment Type Naming Conventions used in this Manual:

Real Time TTL Auto Exposure Adjustment R-TTL

Real Time Auto Exposure Adjustment R-S

Pre-flash TTL Auto Exposure Adjustment P-TTL

External Auto Flash Exposure Adjustment (with pre-flash) P-S

External Auto Flash Exposure Adjustment (without pre-flash) R-S

Manual Flash Exposure Adjustment (with pre-flash) P-M

Manual Flash Exposure Adjustment (without pre-flash) R-M

Reference No. 2 “TTL” – What is it?

TTL stands for Through The Lens; that is, light which passes through the camera lens.

In order to obtain proper exposure, of various methods to measure exposure amount, light passing through the lens and directly striking the light sensitive medium/device (silver halide film, image sensor(CCD) etc.) is metered directly; or, metered indirectly if it is reflected off the light sensitive medium/device.

An external strobe using these TTL metering methods of automatic light control is called a “TTL

Strobe” and an external slave strobe set to synchronize with the master strobe’s flash duration is called a “TTL Slave Strobe”.

For the purposes of this Manual, we distinguish between two types of TTL light adjustment, both of which are common in current digital cameras.

- Real Time TTL Auto Exposure Adjustment

- Pre-flash TTL Auto Exposure Adjustment

Real Time TTL Auto Exposure is when the image is being taken (when the shutter is open), and when TTL metering is occurring and the exposure value is being adjusted in real time.

Pre-flash TTL Auto Exposure Adjustment is when the camera’s internal strobe fires a flash before the shutter opens, and this light reflecting from the subject is metered TTL, and the data resulting from this is used set the main strobe’s actual flash amount, so when the shutter opens and the strobe flashes, the flash output is of a predetermined amount.

Reference No. 3 “Pre-Flash” – What is it?

Camera’s internal strobe fires one or more small flashes before the main flash. Reflected light from the pre-flash(s) is measured by the camera and used to calculate the main flash duration, for correct exposure.

INON D-180 Manual

Version 1. October 4, 2003

15

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

In general, for “Pre-flash TTL Auto Exposure Adjustment” type camera systems, before the shutter opens to actually record the image, the subject reflectivity must be metered in order to calculate the main flash duration (intensity).

In order to meter the subject reflectivity, the camera fist fires one or more small flashes

(pre-flashes) and measures the light reflected back from the subject. Then the camera calculates what it “thinks” the best main flash duration would be to achieve correct exposure. Finally, the shutter opens and the camera’s internal strobe fires its main flash for the pre-calculated duration.

Reference No. 4 “External Auto”

(External Automatic Flash Exposure Adjustment)

A function where a strobe has a light adjustment sensor mounted in the strobe itself, whereby the light adjustment sensor adjusts flash output based on subject reflectivity, for “correct” exposure.

For strobes with this function, by setting the strobe’s Aperture Value to match that of the camera system, at the same time as the camera’s internal strobe fires its main flash, the external strobe’s light adjustment sensor measures subject reflectivity in real time, and automatically adjusts for correct strobe output.

Reference No. 5 “Master Strobe” and “Slave Strobe”

“Master” and “Slave” are terms corresponding to “which strobe is the controlling device” and

“which strobe is being controlled”.

When using two strobes (including the case of the camera’s internal strobe and the D-180), where both the camera’s strobe and D-180 are directly connected to the camera/housing, and are controlled by the same signal, since there is no difference in function, there is no distinction between Master and Slave.

However, it is possible to connect only one of the strobes directly to the camera/housing, with the other strobe connected to the first strobe. The strobe connected to the camera/housing (Master) receives control signals directly from the camera and flashes. At that time, the other (Slave) strobe sees the master strobe’s flash, and at that signal, reproduces the same flash duration as the master strobe. “Master” and “Slave” terms are used when the two strobes have such definite master/slave relationship.

For the purpose of compatibility with the D-180, as of December 2002, most digital camera’s internal strobe is the master strobe, with the external strobe being a slave connection.

Reference No. 6 “Advanced Cancel Circuit”

By proactively utilizing the fundamental light control theory of digital cameras using “Pre-flash

TTL Auto Flash Adjustment”, compared to conventional strobes with simple pre-flash cancel circuits which cause the camera’s internal strobe to emit a full discharge on the second main flash,

INON D-180 Manual

Version 1. October 4, 2003

16

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

the D-180 Advanced Cancel Circuit (patent pending) effectively reduces the internal strobe’s main flash output with the following benefits:

Conserves the internal strobe’s condenser energy so the internal strobe’s recycle time is shortened, allowing quicker follow-up shots.

Reduces energy consumption so more images can be taken per set of batteries.

The Advanced Cancel Circuit reduces the internal strobe’s second main flash by first telling the

D-180 to reproduce (in real time) the camera’s pre-flash, but at a multiple of the actual camera pre-flash output. (e.g., In the case of the C-3030/3040 pre-flash, the D-180 emits its own pre-flash but at 22 times higher intensity.) The actual D-180 pre-flash strength corresponds to the particular camera model’s internal strobe pre-flash intensity.

The purpose and design of the camera’s pre-flash is to illuminate the subject in air, in order to calculate the main flash duration. The camera’s pre-flash intensity and main flash exposure calculation method were not designed to be used in water, where much of the pre-flash’s light is absorbed in the water between the camera and subject. The camera, receiving little reflected light back from the subject, thinks “Oh my, it is really dark out there.” and tells the internal strobe to emit a full discharge, hoping to sufficiently illuminate the subject. So the internal strobe fires a full “dump” of light and releases all the built-up energy stored in its capacitor. It then takes a few seconds for the energy to build up again before another image can be taken.

In contrast, in addition to the internal strobe’s pre-flash intensity, the D-180 calculates its pre-flash based on the fact that the pre-flash must pass through water (not air) on its way to the subject and back again to the camera. When the camera receives more light from the D-180 pre-flash, it does not “think” it is so dark and fires its main flash at reduced output, conserving stored energy in the internal strobe’s capacitor, enabling the strobe to recycle faster, shortening the interval between shots and allowing more shots per set of batteries.

Reference No. 7 “Clear Photo System”

The Inon “Clear Photo System” helps produce clearer better images, shortens the camera’s internal strobe re-cycle time for quicker follow-up shots, and prolongs the camera’s battery life.

No Backscatter: The most important function is to minimize incidence of “marine snow”

(backscatter). Backscatter is when particles suspended in the water in front of the lens are illuminated by the camera’s internal flash, resulting in a “blizzard” effect of white specs in the image. Or, if the particles are very small, the resulting image may look hazy or out of focus.

Clear Photo System works by first placing a visible light cut filter (“Clear Photo Filter”) over the camera’s internal strobe. This filter only lets the non-visible wavelengths pass through.

Accordingly, there is no visible light coming from the camera to illuminate the particles and cause backscatter. The D-180 does not need a visible light signal from the master strobe to function.

INON D-180 Manual

Version 1. October 4, 2003

17

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

The non-visible light which passes through the Clear Photo Filter is picked up by an Inon “Optical

D Cable” fiber optic and guided to the D-180’s slave sensor. When the D-180 receives this light signal if fires. Since the D-180 can be mounted externally, at an angle away from the camera, the strobe’s light beam can reach the subject without illuminating the water and particles between the camera and subject. Another benefit of Clear Photo System is no stray light from the internal flash causing ghosts or flare inside the housing, port tube barrel or attachment lenses.

Clear Photo Film is included with Inon “Optical D Cable/Cap Sets” which are available for many popular camera/housing models. Refer to the User Manual with your Optical D Cable/Cap Set.

Connecting D-180 to Camera System

The D-180 can receive strobe control signals several ways. Depending on how you intend to use the D-180 will determine the control signal reception method, and the way of connecting the

D-180 to your camera/housing/master strobe system. Before attempting to use your strobe, it is important to understand the connection method relevant for your situation.

The D-180 can be connected to your camera/housing/master strobe system as follows:

1) Using D-180 as an external Slave Strobe to digital camera’s internal strobe (Master Strobe)

(*1)

Optical D Cable Connection

Select an Inon “Optical D Cable/Cap Set” specified for your camera/housing, and connect one end to the Master Strobe/Housing, and the other end to the D-180 Slave Strobe. The

Master Strobe transmits light through the fiber optic cable to the D-180’s Slave Sensor.

As the Slave Strobe, the D-180 fires and quenches when it senses “correct” exposure.

2) Using external D-180 as a Slave Strobe to another external strobe (Master Strobe)

(*2)

Optical Slave Cable

Connect an Inon “Optical Slave Cable”

(*3) between the D-180 and the other external strobe. The other external strobe (Master Strobe) transmits light though the fiber optic cable to the D-180’s Slave Sensor. As the Slave Strobe, the D-180 fires and quenches when it senses “correct” exposure.

4) Using D-180 as a Master Strobe to another external strobe (Slave Strobe)

Optical D Slave Cable Connection

Connect an Inon “Optical D Slave Cable”

(*4) between a D-180 or Z-220 strobe (Master

Strobe) and an Inon Z-220 or Z-220 strobe (Slave Strobe). Light from the D-180/Z-220

Focus Light will link to and allow functioning of the slave strobe’s Focus Light and Target

Laser.

(*1) Wireless slave connection not possible. Optical D Cable necessary.

3. Light Adjustment Sensor

When using External Auto, this sensor measures the light reflected back from the subject.

For details on use of +1/4 EV Compensation Switch, see Page 38, “+1/4 EV Compensation

Switch Use Method”.

5. Slave Sensor

This sensor receives light from the master strobe, either via an “Optical D Cable”, an

“Optical Slave Cable” or and “Optical D Slave Cable.” For details on connecting to camera/housing systems see Page 23, “Confirming Connection Method”.

10. Strobe Ready Red Lamp

Lamp turns red when strobe charge complete.

The Red Strobe Ready Lamp will activate when the strobe re-charge is 80% complete. For situations where more precise output is necessary, such as manual flash, or for External Auto when the subject is distant and at the far end of the strobe’s auto exposure effective working range, necessitating a full strobe discharge, we recommend you wait an additional one second after the Strobe Ready Lamp comes on.

INON D-180 Manual

Version 1. October 4, 2003

27

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

11. “TTL” OK Green Lamp

When the strobe light adjustment mode is set to External Auto, and the image is taken and exposed properly within the “External Auto Exposure Adjustment Range” the lamp will shine green. But if the subject is not within the range, for example, too far away for the strobe light to adequately reach, causing the strobe to emit a full discharge, then the lamp will not shine.

12. Battery Box

Caution: Be very careful that no water enters the Battery Box or contacts the terminals on the Battery Box Inner Cap. If even one small drop of water enters for even a short period of time it may result in an electrical short, corrosion damage, cause buildup of flammable gas, lead to explosion or other accident. In particular, when removing the Battery Box Outer

Cap, follow these precautions:

1. First rinse with fresh water and dry area around the Battery Box. (Assuming strobe is wet with salt water)

2. To prevent any water from entering the Battery Box, hold the Battery Box so the

Battery Box Outer Cap is facing down.

3. Also, unscrew the cap slowly.

Chapter 2 Preparation and Set-up

Camera System Preparation

When using with digital cameras make the following three settings:

Set the camera’s internal strobe to “force-flash”, “fill-in-flash”, “anytime flash” or similar mode where flash will always fire.

When using the D-180’s External Auto Flash Exposure Adjustment feature, it is also necessary

to pre-set the camera’s ISO sensitivity, Shooting Mode and Aperture Value to suit the conditions particular to your situation.

Also, to obtain “correct” exposure or the exposure you visualize as optimum, depending on the subject reflectivity and shooting conditions it may be necessary to use exposure compensation on the camera and flash output compensation on the D-180.

For details on how to set the ISO Sensitivity, Shooting Mode and Aperture Value for your particular camera, refer to your camera manual.

When D-180 is configured with digital cameras it is necessary to set the D-180’s Aperture Value to match the camera’s aperture value setting, when the camera’s ISO sensitivity is set to a base-line

ISO 100. We recommend setting the camera as follows, as an initial standard setting.

1) Set the camera’s ISO sensitivity to “ISO 100” on camera’s that allow such setting.

2) Set the camera’s “Shooting Mode” to a mode that allows setting the Aperture Value, if your camera allows such setting.

3) Set your camera’s Aperture Value to a value that reflects your creative intent and the requirements of your particular imaging situation.

4) Set the camera’s “Flash Mode” to “force-flash”, “fill-in-flash” or “anytime flash”.

5) As necessary, set camera exposure to –1EV to -2EV, especially for macro imaging.

After setting the strobe and shooting some images it is possible to adjust further as follows.

6) After taking the image and reviewing it on the LCD monitor, in accordance with your intended results and the shooting conditions, adjust the camera’s aperture value, the camera’s exposure compensation (on camera’s that allow this), and/or the D-180’s flash output compensation.

For camera’s that do not allow setting the ISO sensitivity or do not have a Shooting Mode that allows setting the aperture value, refer to the camera’s LCD monitor display, the camera manual and the lens specifications as printed on the lens itself. We recommend checking this information

INON D-180 Manual

Version 1. October 4, 2003

29

and filling in the blanks below.

1) ISO sensitivity effective range ISO to ISO

2) Largest aperture value (at both Tele and Macro) W:f/ - T:f/

3) Smallest aperture value (at both Tele and Macro) W:f/ - T:f/

Naming conventions of cameras having shooting modes capable of settable aperture values:

Olympus A (Aperture Priority Mode) / M (Manual Mode)

Canon Av (Aperture Priority AE) / M (Manual Exposure)

Nikon A (Aperture Priority Auto) / M (Manual)

By setting the D-180 to External Auto as described above, imaging with external strobes is easier compared to conventional strobes using manual flash adjustment. However, in order to achieve

“proper” exposure of various subjects and shooting conditions it is necessary to have a deep understanding of “exposure”, especially the relationship between exposure from natural ambient light and exposure from strobe light. (See Ref. No. 8, page 42)

Digital Camera Setting Example No. 1A (Olympus C-4040 Zoom)

(And for cameras having settable ISO, Aperture Value, and with Aperture Value visible in LCD display)

1) Turn Mode Dial to “A/S/M”, push “OK/MENU” Button, push camera’s Arrow Pad control to

RIGHT and enter “MODE MENU”.

2) In the MODE MENU Tabs, set ISO to “100”; and then “A/S/M Mode” to either A (Aperture

Priority) or M (Manual).

3) Push OK/MENU to complete this setting.

4) Push Flash Mode Button to Fill-in Flash.

5) If the camera is set to Aperture Priority Mode, push the

Arrow Pad either up or down and choose an aperture value. If camera is set to Manual Mode, push Arrow

For situations where more precise output is necessary, such as manual flash, or for TTL when the subject is distant and at the far end of the TTL effective range, necessitating a full strobe discharge, we recommend you wait an additional one second after the Strobe Ready Lamp comes on.

Also, when the batteries are near exhaustion the voltage level tends decreases, and the actual strobe output may be slightly less than indicated. Alkaline batteries especially have this tendency for voltage to decrease, so also consider this factor when precise and/or full strobe output is necessary.

Focus Light Switch Setting Method

Focus Light mode functions, control and switch position are as follows:

OFF MODE (position set at “LIGHT” as in figure to right)

Set in this position to turn Focus Light off.

Single MODE (*)

Push Focus Light switch once and release. The Focus Light will turn on and then turn off automatically as the internal strobe fires; or, if shutter not released, after about 8 seconds.

Continuous MODE (*), (**)

By pushing Focus Light switch continuously, or by turning it to either right or left “Lock” positions while pressing, the Focus Light will turn on and shine continuously until the shutter is released. Then, the Focus Light will turn on again automatically 0.5 seconds after the image is taken.

(*) The Focus Light automatic off function is triggered by the Master Strobe’s flash. Therefore, the Focus Light automatic off function is not recommended for use with R-TTL, R-S and R-M

Group digital cameras having internal strobes, or with other external strobes (that do not use pre-flash type of exposure calculation). The shutter-linked automatic off function will not work and light from the Focus Light will be recorded in the image. Turn the Focus Light OFF before releasing the shutter.

(**) In Continuous MODE, after the shutter is released, the Focus Light will turn off for approximately 0.5 seconds, before turning on again. Therefore, for slow shutter speeds longer than 0.5 seconds, do not use the Focus Light in Continuous MODE, since the light will turn back on while the shutter is still open, exposing the image with light from the Focus Light. Instead use

OFF MODE or Single MODE.

Troubleshooting External Auto Flash

When using strobes, depending on the particular shooting conditions, subject characteristics and desired image characteristics, it is very important to consider the total light of, and balance

between both the natural ambient light and the strobe light. Also, it is necessary to keep in mind the general characteristics of digital cameras and how the D-180 handles external auto flash.

Here are some common situations, with causes and possible solutions.

1) Macro Imaging

Problem Blooming, image highlights washed out, overexposed, too bright.

Cause 1 Because the amount of strobe light exposing the subject is small, the proportion

of natural light reflecting off the subject is greater. After the strobe stops firing, when it thinks proper exposure has been reached, natural light continues to expose the subject until the camera shutter closes, and the digital camera’s exposure latitude is overcome. compensation) to –2 EV, etc.

Solution 1-2: If using Aperture Priority or Manual Mode, stop down aperture on camera, for example from f/4.0 to f/8.0 or f/11 etc.

Solution 1-3: If using Manual Mode, increase shutter speed, for example from 1/60 to 1/125 or

1/180 etc.

Solution 1-4: Attach optional D-180 diffuser panel to strobe to decrease flash output.

Cause 2 When subject has depth there is a difference light amount reaching the front and back, causing overexposure on the front or foreground, overcoming the digital camera’s exposure latitude.

Solution 2-1: Adjust strobe to minus compensation, for example if the camera aperture is f/8.0, set the strobe to f/5.6 or f/4-1/2 etc.

INON D-180 Manual

Version 1. October 4, 2003

39

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

Solution 2-2: Using strobe arms, move strobes farther away from subject to reduce amount of light reaching the subject.

Solution 2-3: Attach optional D-180 diffuser panel to strobe to decrease flash output.

2) Mid-range Subject Imaging

Problem

Blooming, image highlights washed out, overexposed, too bright. an open water background, only a small amount of light will be reflected off the subject and back to the D-180’s light sensor. The strobe, sensing very little reflected light (under exposure) will try to emit more light than necessary, and overexpose/wash-out the subject. This is a difficult situation for any camera/strobe system.

Solution 1-1: Adjust strobe to minus compensation.

Solution 1-2: As needed, set camera’s exposure compensation.

3) Using Multiple Strobes (including camera’s internal strobe)

Problem

Blooming, image highlights washed out, overexposed, too bright.

(external strobe(s) + internal strobe) is too great at close distances, causing the close end (nearest the camera) of the effective flash exposure range to lengthen out, away from the camera. Subjects close to the camera/flash will receive too much light and be overexposed. This is particularly the case for camera’s having internal strobes with relatively large minimum possible flash output. For such cameras we recommend placing Clear Photo System film over the internal strobe when using external strobe(s).

Solution 1-1: Use Inon “Clear Photo System”

Solution 1-2: Stop down camera’s aperture value.

Solution 1-3: Adjust strobe to minus compensation.

Solution 1-4: Using strobe arms, move strobes farther away from subject to reduce amount of light reaching the subject.

Solution 1-5: Attach diffuser panel to strobe(s) to decrease flash output.

Cause 2

When using strobes other than Z-220 as TTL Slave strobes when the D-180 is the

Master strobe, the effective exposure range is insufficient and/or the recycle time is too long (for use with pre-flash systems etc.) making proper exposure difficult or not possible.

Solution 2: Use Z-220.

INON D-180 Manual

Version 1. October 4, 2003

40

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

4) Distant Subject Imaging

Problem

Subject is underexposed, too dark.

Cause

Subject is too far away, beyond strobe’s effective range so adequate light is not reaching subject.

Solution 1: Move closer to subject, to within the strobe’s effective range.

5) Advanced Techniques (slow synch imaging / using auxiliary

strobes)

Problem

Blooming, image highlights washed out, overexposed, too bright.

Cause

The proportion of exposure due to natural light is comparatively greater, so that even after the strobe stops firing at what it thinks is “proper” exposure, the shutter is still open adding natural light exposure, causing total exposure to exceed the camera’s exposure latitude.

Solution 1-1: Adjust strobe to minus compensation.

Solution 1-2: Adjust other shooting parameters on the camera.

6) Advanced Techniques (back-lit subjects)

Problem

Difficulty to achieve intended image.

Cause

The balance of natural light to strobe light is improper for the camera shooting parameters.

Solution 1: Set strobe flash output compensation and camera exposure compensation according to the subject reflectivity, background brightness and to what degree the subject fills the frame. In general, set camera exposure to plus (+) compensation and strobe flash output to minus (-) compensation.

Adjusting D-180 Flash Output

It is not necessary to always exactly match the Aperture Value Set Switch to the camera’s aperture value. However, in addition to the various situations described above , depending on the subject condition and the D-180 strobe position relative to the subject and camera, there may be a difference between the subject reflectivity measured by the D-180, and the subject reflectivity metered through the camera lens. Exposure difference may vary based on camera manufacturer and camera model, as well as other factors.

To obtain optimum exposure in such cases, after double checking that the Aperture Value setting on the strobe matches the camera aperture in the camera monitor, if proper exposure still not obtained, adjust the Aperture Value Set Switch for flash output compensation as described below.

Note: In general, the images on consumer digicam monitors often appear a little overexposed, so to

Reference No. 8 Exposure when using strobes

When using strobes to take images, the kind of light exposing the film/image sensor increases from just one type; natural Ambient Light, to two types; Ambient Light and Strobe Light. Therefore, when Strobe Light becomes a factor, in order to expose the image according to your intention, you must first image in your mind:

1) The combined total exposure amount of Ambient and Strobe Light

2) The balance between the Ambient and Strobe light in the total exposure amount, and how to match the camera parameters for each subject and shooting condition to appropriately control the outcome.

Considering the light exposure from the Film or Image Sensor’s perspective, the characteristics of

Ambient and Strobe light can be compared as follows.

Ambient Light

Comparatively weaker than strobe light, but exposing for the whole time the shutter is open.

Exposes subject, foreground and background equally based on the ambient conditions.

Strobe Light

Comparatively stronger than natural light, but only exposes for a brief instant while the shutter is open.

Because much of the strobe light will be absorbed by water, amount of strobe light reaching the subject, foreground and background is different. Objects closer to the strobe will receive and reflect more strobe light. Distant objects or background may not receive any strobe light at all.

INON D-180 Manual

Version 1. October 4, 2003

42

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

Methods for controlling the Ambient and Strobe Light are different.

When using the D-180 on “External Auto” mode, with the camera’s ISO to 100, the ambient and strobe light are controlled as follows:

Ambient Light The strobe’s setting does not make any difference.

Camera’s Aperture Value: As the aperture becomes smaller (the “f/ stop” number becomes larger, for example f/8.0 instead of f/5.6), less light passes through the lens and so the amount of exposure decreases (in Manual and Aperture Priority Modes). When using Exposure

Compensation with Shutter Priority Mode, the camera’s aperture value will change as well.

Camera’s Shutter Speed: As the speed becomes faster (the fraction becomes smaller, for example 1/125 of a second instead of 1/60), less light passes though the lens and amount of exposure decreases (in Manual and Shutter Speed Priority Modes). When using Exposure

Compensation with Aperture Priority Mode, the camera’s shutter speed will change as well.

Strobe Light Directly related to the camera’s aperture setting.

D-180 Aperture Value Set Switch Value: In contrast to setting the camera’s aperture value; 1)

Dialing the Aperture Value Set Switch to a larger aperture value (smaller number) will reduce the flash amount (weaker). 2) Dialing to a smaller aperture value (larger number) will increase flash amount (stronger).

D-180 +1/4 EV Compensation Switch: Moving switch to ON position (so that it covers the

Light Sensor) will increase exposure by +1/4 EV. Flash light becomes stronger.

Reference No. 9 Differences between using external strobes with digital cameras and film cameras

Image Sensor Latitude

Compared to silver halide film, consumer grade compact digicams have narrower image sensor latitude and less dynamic range. This means there may be less possible contrast gradations, loss of shadow details, increase of blooming – washout of highlights etc. Accordingly, more precise control of natural light and strobe light is increasingly important.

Image Sensor Size and Lens Focal Length

Because the image sensor size of consumer digicams is small (compared to 35mm film systems), extremely short focal length lenses can be used. And because of this, it is possible to obtain much deeper depth of field (compared to 35mm film at the same view angle and optical aperture).

With conventional 35mm film systems, achieving great depth of field, especially for macro imaging, required some skill and know-how, such as aperture setting and strobe placement. But for current digital cameras, obtaining good depth of field is comparatively easier due to the short focal length lenses commonly used. Also, due to current digicams having different

characteristics, the basic functionality required of external strobes is also different, and the

External Auto strobe functions of the D-180 have been developed to a high level accordingly.

Reference No. 10 Characteristics of External Auto Exposure Adjustment systems

Strobe Beam Axis Adjustment

Adjust strobe beam direction so focus light shines directly on subject. This is necessary so the flash will illuminate the subject, and also so the light adjustment sensor directly faces the subject and receives the reflected light. This is important for proper functioning of External Auto type strobes.

Strobe Position and Beam Angle

As the strobe is positioned farther away from the camera (the angle between the camera lens axis and the strobe becomes greater), depending on the subject and shooting conditions, the subject reflectivity that the camera measures compared to what the D-180’s light adjustment sensor measures could be very different and “correct” exposure may not be obtained using External Auto.

In such cases, compensate flash output by adjusting D-180 Aperture Value Set Switch.

Strobe Light Adjustment Timing

Compared to conventional silver halide film camera systems using external strobes with TTL automatic light adjustment, when using external strobes with External Auto light adjustment, the strobe itself determines the strobe’s output and when to quench (for D-180, in less than 1/1,000 of a second).

However, even after the strobe flash stops, the shutter may remain open and exposure from natural ambient light will continue until the shutter closes, especially for non-real-time light adjustment cameras, such as those using pre-flash. The external strobe does not consider, or calculate for natural light exposure after the flash stops firing.

Accordingly, for imaging where exposure from natural light is a large proportion of the total exposure (macro / slow synch / bright conditions etc.), use exposure compensation on the camera, and/or strobe output compensation on the strobe.

Setting Manual Flash Output

When using strobes there is an intimate relationship between the Aperture Value and the shooting distance. In air, the following formula may be used to calculate the correct aperture value.

Strobe’s Guide Number

÷

Distance to Subject

=

Correct Aperture (at ISO 100)

However, light is absorbed very quickly as it travels through water so that it does not completely reach the subject as it would in air. Accordingly, it is often advised to open the aperture one or

two stops to allow more light to reach the film/image sensor, compensating for the light absorbed by the water. Note: In water, the visual distance to the subject is about 0.75 times the actual measured distance.

Because proper Aperture Value / Guide Number may vary due to water conditions, strobe angle and distance relative to subject, subject reflectivity, amount of magnification of lens and various other factors, learn by taking test images, build up experience and adjust manual settings according to the situation.

Also note that as the distance from camera lens to subject becomes shorter, the camera lens tends to become “darker” and less light will reach the film/image sensor. Adjust settings accordingly.

Also, be aware that natural light may increasingly contribute to the exposure based on you settings, so taking test images and analyzing the exposures is useful.

The chart below should be used as an initial reference guide for setting manual exposure, and supported with actual testing and experience to obtain optimum images.

How to interpret the exposure calculations

For example, when the film/image sensor ISO value is 100, and the distance to subject is 0.9 meters / 3 feet (underwater visual distance), at FULL flash, -2 flash and –4 flash settings, the aperture settings would be either f/9, f/4.5 or f/2.2 respectively.

Chapter 4 D-180 Care and Maintenance

To obtain best performance from your D-180, please follow these preventative care and maintenance guidelines.

1) Protect the D-180 from excessive impact shock and vibration. Do not drop. Do not leave on a vibrating boat deck without some cushioning, for example. Especially, protect the Optical Sensor. Use some towels or padding under the arm connector (see figure at right) to prop up the strobe so there is no pressure exerted on the Optical Sensor/Connector.

2) Do not leave strobe exposed to direct sunlight or other areas of high temperature.

3) Do NOT disassemble or attempt to self-repair. The strobe contains very high voltage circuitry. Disassembling could lead to severe electric shock and injury. If you think the strobe is in need of repair, always contact Inon or your Inon dealer.

4) Do not leave the strobe closed when traveling to or from high altitudes, including travel on aircraft. Always remove the Battery Box Cap.

5) When changing batteries use extreme care to prevent any water from entering the strobe or battery connection terminals. Where possible, avoid battery changes when the strobe is wet.

6) Limitation on number of continuous repeated strobe flashes

In order to prevent overheating and damage of D-180 flash tubes and internal circuitry, do

not repeatedly discharge the strobe more than recommended limit.

Limit the number of continuous repeated strobe discharges according to the chart below.

After reaching the limit, stop and let the strobe cool off for two minutes minimum. In general, it is preferable to let the strobe cool off anytime after a continuous burst of flashes, even if less than the maximum below.

*When subject is at far (distant) side of light adjustment range, or shooting conditions cause the strobe to discharge in the FULL to –0.5 range.

7) Important points regarding battery handling and care

The D-180 uses four AA Alkaline, Nickel Cadmium (NiCad) or Nickel Metal Hydride (NiMH) batteries.

In general, as batteries are used, the battery voltage gradually decreases and it takes longer for the strobe to recycle after firing. As the batteries discharge, when using manual flash exposure, the flash output amount (Guide Number) may become slightly less than actually indicated. As

INON D-180 Manual

Version 1. October 4, 2003

46

batteries discharge further, towards complete exhaustion, there will be a sharp reduction in voltage possibly causing the strobe to function inconsistently.

If you observe any of the following symptoms, it may be that the strobe is not receiving sufficient voltage necessary for correct function.

When Focus Light brightness becomes dimmer.

When it takes the Strobe Ready Red Lamp over 30 seconds to shine when using alkaline batteries;

Or, when the Strobe Ready Lamp recycle time takes over 8 seconds for NiCad batteries.

In general, battery performance will decrease as temperature lowers, and batteries will slowly discharge over time when not used. And, number of possible flashes can greatly vary based on variables such as water temperature and how the batteries are used. If possible, start with a fresh or sufficiently charged set of batteries so that you do not end up with exhausted batteries in the middle of a dive, and loose important imaging opportunity.

Follow these precautions to avoid damage to batteries and strobe, and depending on the type of batteries, possible buildup and explosion of flammable (hydrogen) gas.

Warning: Equipment damage or personal injury may result if these precautions are not followed.

A. Make sure battery +/- positions are properly placed in Battery Box.

B. Do not use non-specified batteries, such as Lithium or Manganese batteries.

C. Do not mix batteries from different manufacturers, or batteries having different remaining charges.

D. Do not mix different battery types together, such as Alkali and NiCad.

E. Do not attempt to charge non-chargeable batteries.

F. Do not intentionally short the batteries or circuits.

G. Do not store batteries in D-180 when not in use.

H. Do not use battery charging devices that are not compliant with the battery manufacturer’s recommendations.

I. Do not repeatedly fire the D-180 to discharge/refresh rechargeable batteries, or any other time.

Caution: Never repeatedly fire the strobe continuously, for example, to discharge or refresh the batteries. Repeatedly firing the strobe will cause overheating and damage internal components.

Caution: If any water ever enters the Battery Box, or if you ever feel suspicion that the

D-180 is not operating correctly:

1. Immediately stop using D-180.

2. Promptly remove batteries.

3. Contact Inon or your Inon dealer for advice. Service may be necessary.

4. Do not attempt to use the strobe, disassemble or self-repair.

8) Maintenance of rechargeable battery terminals and D-180 Battery Box terminals

Rechargeable batteries offer high capacity, high performance and long life but to ensure consistent and stable function it is necessary to monitor the both the battery terminals and the D-180 Battery Box terminals, and perform maintenance according the procedures below. Also, anytime you suspect inconsistent charging, unstable performance or poor battery connection, check the terminals as an initial troubleshooting measure.

1. Adjust position of Battery Box Inner Cap terminals

High performance rechargeable batteries can be heavy, and may tend to flatten the

Battery Box Inner Cap terminals. This can cause poor connection, so gently bend the terminals back to the correct position, as in image below.

Correct

Position

Incorrect

Position

2. Clean battery terminals, Battery Box Inner Cap terminals and Battery Box terminals

High performance rechargeable batteries have a tendency to form an oxidized layer or build up residue on the battery terminals and Battery Box terminals. This can cause poor connection, so clean the terminal locations as in images below.

Cleaning Method

Terminal Cleaning Locations

a) Wipe each terminal surface with a cotton swab (or similar) soaked in alcohol to remove any oil or similar residue.

INON D-180 Manual

Version 1. October 4, 2003

48

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

b) If above step does not fully clean the terminal, dap a small amount of silver polish on a cotton swab (or similar) and wipe terminal surface until fully clean. Then clean off any silver polish residue with a clean swab.

Note: When cleaning, be careful not to let any alcohol or silver polish contact any plastic or vinyl parts.

Caution: When handling batteries always follow the handling precautions listed on page

47 .

Caution: Whenever installing batteries always turn Main Mode Switch to OFF.

Post-dive care

1) After using strobe underwater, first rinse and then soak in fresh water, for several hours if possible, to dissolve any salt build-up. The water temperature should be no higher than 30C (86F) degrees. Do not immerse the strobe into hot water.

2) When soaking in fresh water, slowly manipulate the controls to work out any salt or sand trapped in the gaps.

3) Take care to rinse especially well the Optical Sensor. If salt is allowed to buildup, it may cause the clear resin portion to become hazy and prevent light from reaching the sensor.

However, do not scrub the sensor with anything abrasive that could scratch the sensor surface.

4) After soaking, do not leave in direct sunlight. First, thoroughly towel dry and remove the batteries. Then place in shaded, well ventilated area. In areas of high relative humidity it may take several days for moisture in the small gaps and recesses of the strobe to completely dry. Never apply flame or direct heat to the strobe.

5) After completely dry, inspect the O-ring, O-ring groove and O-ring contact surfaces, and maintain / grease-up as necessary.

Caution: If the strobe exterior needs cleaning, do not use alcohol, benzene or solvent based cleaning solutions. Also, never use alkali cleaning agents or other chemicals as these will degrade the plastic body. Use a mild well diluted (neutral) detergent if exterior cleaning absolutely necessary.

Overhaul

The D-180 is designed and manufactured for use in severe conditions. Before shipping, all strobes are pressure tested in water and fully checked for proper function. To ensure your D-180 maintains optimum performance, in addition to the pre and post dive handling recommendations, maintenance procedures, and recommended storage conditions, it is also necessary that the strobe receive periodic overhaul at Inon, or an Inon authorized service facility.

INON D-180 Manual

Version 1. October 4, 2003

49

Copyright 2002, 2003 by INON America, Inc. All rights reserved.

There are two main types of overhaul:

1) Normal Overhaul

Replace any exposed O-rings

Replace any O-rings supporting moving parts

Test all controls, moving parts

Pressure test

2) Full Overhaul

Replace all O-rings

Test all controls, moving parts

Pressure test

O-ring and other degradable part life can vary considerably due to type of use, frequency of use, maintenance method, storage conditions etc. Inon will conduct incoming product inspection of each overhaul request and determine at its discretion whether Normal or Full Overhaul is necessary.

Of course, Inon can conduct overhaul and any time based on specific instructions from the user, but in general Inon recommends normal overhaul once per year, and full overhaul every three years.
