3. Incident Measurement Mode

Incident light measuring is the measurement method that employs either the Lumisphere or Lumidisc functions.

Measurements should be with the Lumisphere aimed towards the camera direction from the subject position.

4. Basic Operation

1. You can select extended or retracted lumisphere measuring positions by rotating the Lumisphere retracting ring (clockwise or counter-clockwise) until it clicks into position.

Extended Lumisphere Retracted Lumisphere

(Lumidisc)

2. When the Lumisphere is extended. (3-D Light Measurement)

This is used to measure people, buildings, and other three dimensional objects.

Measurements are basically made by the method of measuring with the lumisphere aimed in the camera direction (more precisely, in the direction of the lens axis) at the position of the subject.

3. When the Lumisphere is retracted (flat diffuser function)

This is used to measure manuscripts, paintings or other flat copy. It can also be used for Contrast function (see page 36) or measuring illumination (see page 38).

NOTE:

• If the light meter is used with the Lumisphere retracting ring in a middle position, distributed light quality will change, and suitable measurements cannot be made.

• Do not push the Lumisphere down with your finger or hand. Always use the Lumisphere retracting ring.

• If the lumisphere becomes soiled, wipe it with a soft, dry cloth. Organic solutions (paint thinner, benzene, etc.) must not be used under any circumstances.

-13-

4. Basic Operation

4. Reflected Measurement Mode (spot metering)

This method measures the brightness (luminance) of the light reflected from the subject. It is useful for distant objects such as landscapes, when you cannot go to the position of the subject, or for metering subjects that generate light

(neon signs, etc.), highly reflective surfaces or translucent subjects (stained glass, etc.).

1. Take the measurement by aligning the circle inside the viewfinder with the subject area to be measured.

2. The black circle A in the finder indicates the measurement range. The light receiving angle is 1 degree .

A

(Display in spot viewfinder)

< Diopter Adjustment >

Turn the eyepiece and adjust the diopter so that the circle in the finder is clearly visible when you look into the finder.

< Step-Up Ring (Lens Hood)> (optional)

The step-up ring (30.5mm → 40.5mm), available as an optional accessory, makes it possible to mount step-up rings and filters. This simplifies the setting of exposure without the troublesome correction calculation of polarizing filters, etc. (see page 56)

The step-up ring can also be used as a lens hood to prevent lens flare and erroneous light measurements from glare, it also protects the spot lens from scratching, soiling, etc.

2-5 Flash analyzing function

When measuring flash light, the shutter speed and F stop value (combining ambient light and flash light: total amount of light) are displayed on the LCD screen and the ambient light and flash light are each displayed as separate values along with the total amount of light (combined flash and ambinent) on the analog scale. In addition, the ratio of flash light to the total amount of light is displayed as a percentage (in 10% steps) at the sametime. The ratio of flash to the total amount of light is useful when a desired flash to ambient lighting ratio is needed.

< Example >

Under certain conditions, if the flash light output is

60% and the available light output is 40%, the LCD screen will display the flash measured value on the analog scale with a faster blinking icon than the total exposure blinking icon.


1. To emphasize the ambient light (to create a more natural lighting condition) increase the ratio of ambient light,(use the Jog wheel ⑤ )by changing the shutter speed to a slower setting.The ratio of flash light in the total exposure will be reduced (as shown in the diagram to the right - 20%).The

analog scale also shows the ambient output to be about 2.5 stops higher than the flash light output.As

a result,images will exhibit a natural lighting quality with flash filled shadows without an over powering presence of flash.

Ambient Flash Measured f stop

(total exposure)

2. To reduce the effect of ambient light decrease the ratio of ambient light, (use the Jog wheel) by changing the shutter speed to a faster setting. The ratio of flash in the total exposure will be increased

(as shown in the diagram to the right – 80%) The analog scale also shows the flash light output to be about 1.5 stops higher than the ambient light output.

(Display in spot viewfinder)

Reference:

• Slower shutter speeds allow more available light to reach the film or digital camera sensor, and faster shutter speeds reduce the amount of available reaching the film or sensor.

• The settings above are made by adjusting the ambient light by the shutter speed. It is also possible to modify the ratio by adjusting the flash light (when changing the distance between the flash and the subject or when changing the amount of light of the flash). When using this method, re-measure each time the flash light is adjusted.

Reference:

•

Refer to the radio Receiver or Transceiver instruction manual for the recommended operating method.

•

Maximum distance of the wireless flash radio triggering system can vary depending on the placement of the remote Receiver or Transceiver, direction of the radios antenna, distance from a large body of water or concrete wall and other possible factors.

1. Confirm the range between the meter (transmitter) and Receiver or Transceiver.

2. Place the meter and Receiver or Transceiver away from large metal objects, concrete, objects, large moisture content (both people and trees fall into the category) and so forth.

3. Secure the radio Receiver or Transceiver in place by using Velcro tape or a 1/4-20 mounting screw. Be sure that the entire length of the Receiver or Transmitter antenna is higher than the flash pack. Avoid contact between the Receiver or Transceiver antenna and metal objects at all times.

4. Depending on the location, there may be cases when the Receiver or Transceiver is incapable of receiving any radio signals whatsoever. There are several possible causes for this such as radio signals reflected off of nearby objects. This can generally be resolved by shifting the meter (Transmitter) or the Receiver or Transceiver slightly in one direction or another. In addition, confirm that the Receiver or Transceiver is not placed behind objects that readily absorb or deflect radio signals such concrete, metal, low hills, etc.

6. How to use the Exposure compensation function

Exposure compensation can be made in precise 1/10 step increments in a +/- 9.9 EV range. Exposure compensation may be necessary when compensation for filters, bellows, extension tube, etc is required.

1. Set the measurement mode (incident light, reflected light) for the desired compensation. You can make calibration compensation independently for both incident, and reflected light. It is not possible to switch between measurement modes if the setting is not completed.

2. Making a plus compensation will increase the exposure. Hold the ISO1 button and the ISO 2 button and turn the Jog wheel counter clockwise. The

will appear in the upper section of the LCD screen.

The compensation will change in +0.1 EV steps up to

+9.9.

3. Making a minus compensation will decrease the exposure. Hold the ISO1 button and the ISO 2 button and turn the Jog wheel clockwise.

The will appear in the upper section of the LCD screen. The compensation will change in -0.1 EV steps up to -9.9.

NOTE:

• When making compensations, be sure that it satisfies your needs based on the results of your digital camera sensor or film be used.

• While incident and reflected light can be set independently, be aware that both ambient light and flash exposure are corrected uniformly.

• Compensation effects every mode of the meter.

If recalibration has been made for specific purpose do not forget to return to original zero settings.

-40-

Reference:

• When compensation is activate, a plus ( ) or minus ( ) sign as well as the amount of compensation is displayed continuously on the LCD. You can set custom settings so that a plus ( ) or minus ( ) sign as well as the amount of compensation doesn’t appear on the

LCD. (See page 44)

• You can also set custom setting so that making a plus compensation results in a decreased exposure (increasing the value of the aperture or shutter speed value) and making a minus compensation results in and increased exposure (decreasing the value of the aperture or shutter speed).


7. How to use Calibration compensation function

Calibration compensation can be made in precise 1/10 step increments in a +/- 1.0 EV. It provides the ability to match exposure measurements with meters to meters, correct exposure for special requirements, adjusts for film or digital cameras,etc.

1. Set the measurement mode (incident light, reflected light) for the desired compensation. You can make calibration compensation independently for both incident, and reflected light. It is not possible to switch between measurement modes if the setting is not completed.

2. To enter the calibration setting of the meter it must first be turned off. Press the power button on while holding down the ISO1 and ISO2 buttons simultaneously. You can release the power button, however please keep pressing both ISO1 and ISO2 buttons; the screen will display CAL 0.0 (for calibration).

3. The calibration setting can be changed by rotating the Jog wheel while pressing and holding down the ISO 1 and ISO 2 buttons simultaneously. A range of +/- 1.0 EV in 1/10 step increments is possible for calibration.

NOTE:

• When making calibration compensations, be sure that it satisfies your needs based on the results of digital camera sensor or film being used.

• While incident and reflected light can be set independently, be aware that both ambient light and flash exposure are corrected uniformly.

• Compensation effects every mode of the meter. If recalibration has been made for specific purpose, do not forget to return to original zero settings.

Reference:

• The calibration setting is not displayed on the main screen once it is set.

• You can also set custom setting so that making a plus compensation results in a decreased exposure (increasing the value of the aperture or shutter speed value) and making a minus compensation results in and increased exposure (decreasing the value of the aperture or shutter speed).

7. Camera Exposure Profiling

1. Calibration testing for exposure profiling

A camera exposure profile plays two main roles.

[1] It can be used to display on a light meter the unique dynamic range and clipping point of the digital camera you are using.

[2] To display more accurate exposure values on the light meter, it records unique variations in the camera, lens shutter speed, aperture, etc. that you are using and reflects them in the exposure display.

The L-758DR/L-758D/L-758CINE can be programmed to stored, recall and display up to three different digital cameras.

Below are the following settings that can be programmed into the L-758DR/L-758D/L-758CINE.

1. Compensation value

Compensation value (aperture and shutter speed) can be programmed for a specific camera and hand-held meter. Compensation adjustment is within a +/- 5EV range in 1/10 step increments.

2. Dynamic range (-)

The point at which a given lighting situation (pre-exposure) has surpassed the responds level of a sensor and alerts the shooter of a under exposure situation (Pre-Exposure Warning). These point can be custom set from -7EV to 0EV in 1/10 increments.

3. Clipping point (-)

The point at which the sensor has reached its maximum reproducible shadow details without pixel noise or grain. Dynamic range (-) adjustment is set from -7EV to 0EV in 1/10 step increments.

4. Clipping point (+)

The point at which the sensor has reached its maximum reproducible highlight details without blooming or highlight block up. Dynamic range (+) adjustment is set from 0EV to +7EV in 1/10 step increments.

5. Dynamic range (+)

The point at which a given lighting situation (pre-exposure) has surpassed the responds level of a sensor and alerts the shooter of an over exposure situation (Pre-Exposure Warning). These point can be custom set from 0EV to +7EV in 1/10 increments.

-46-


It is necessary to test the cameras sensitivity, measure the actual dynamic range and know the clipping points of your digital camera and processing used before programming the L-758DR (L-

758D/L-758CINE) meter for Exposure Profiling.

Reference:

• The dynamic range settings and the clipping point settings can be switched, if it is necessary to create clipping points within the dynamic range.In this case, simple enter the dynamic range data in the clipping point cells and the clipping points in the dynamic range cells.

Rain Do not submerge or use under water

-60-

• To avoid damaging this meter, never drop it or subject it to shock.

• Avoid storing it in places with high temperatures or humidity.

• Avoid excessive temperature changes which could cause internal condensation, resulting in malfunction.

• If the temperature of the meter drops to -10 deg. C or beyond, response of the LCD becomes extremely slow and displays are difficult to read. At temperatures between 0 and 10 deg. C the LCD will become somewhat slower than normal but this does not hinder usage. Also, when the temperature exceeds 50 deg. C, the LCD will turn black and will be hard to read. This will return to normal when the temperature returns to normal.

• Do not place the meter in direct sunlight during midsummer or near heaters, etc., as the temperature of the meter will rise beyond that of the air temperature. Be careful when using the meter in hot locations.

Maintenance Notes

• If your meter is splashed with water, wipe immediately with a soft dry cloth. This will cause rust or corrosion.

• Avoid applying excessive force on the rubber seal of the battery compartment cover or attempting to remove it. This will cause inundation, corrosion or malfunction.

• If the rubber seal’s surface is damaged,water or moisture may enter and damage the meter. If this has happened, you must send your meter to the Sekonic Sevice Center in your country.

• When light meter get dirty, clean it with soft dry cloth. Never use organic cleaners (like thinner or benzene).

• Do not operate with battery door open.
