shaping the character of light
Cinematic lighting is craft on a schedule. It has two masters: The director and the clock.
Good lighting is more than just correct exposure. And correct exposure is more than just the
right camera settings. Properly shaped light is vital to storytelling. It directs the viewer and
sets the mood. And correct exposure is critical to achieving full tonality and proper color
saturation. Both have to be done right and done on time. That is why Sekonic is becoming
the cinematographer’s meter of choice.
Light is measured in two ways
Incident Light Metering
Incident metering tells you about the light you are controlling. It’s hemisphere
receptor is designed to integrate all of the illumination that falls on it, and the
subject, including the key light, line light, hair light, eye lights, etc. Besides taking
nearly foolproof exposure readings, incident light meters enable you to set up and
light a scene before the principal talent arrives. They also allow “walking the set”
to measure the evenness of the illumination. The Sekonic L-758CINE and L-358
offer the convenience of a retractable Lumisphere. Retract the Lumisphere to read
individual light sources to adjust them to the desired ratio. Extend it to take an
exposure reading at the subject position.
Reflected Light Spot Metering
Reflected light metering tells you about the scene and subject. Different from
incident light metering that produces readings only for the middle of the exposure
range, reflected light spot metering can show you where the edges are. To get the
most out of a spot meter, use it to measure the brightest and darkest areas you
want in the scene to determine the scene brightness range. This will help you light
the scene to fit your digital camera or film. The L-758CINE’s analog scale, 9-reading
memory and averaging functions enable quick measurement of the brightness
range and producing an averaged center point. Then a simple skin tone or gray card
reading at the talent position will tell you where to start. Spot metering with
this precision requires that you know the dynamic range of your DV camera or film.
The L-758CINE’s Latitude Display can be programmed to mirror the dynamic range
of your digital camera or film.

Sekonic Prodigi Color C-500
Cat# 401-500 (C-500) | Cat# 401-501 (C-500R)
The PRODIGI COLOR C-500 is the first photographic color meter that measures
and displays color temperature and compensation values in LB/CC index or filter
numbers for both DV cameras and film. Working on location with today’s mix of
tungsten, halide, vapor and fluorescent lights can be challenging. The C-500 gives
you the control you need to balance sources and accurately reproduce color tones
from set to set.

The PRODIGI COLOR C-500 and C-500R measure and display color temperature
and compensation values in LB/CC index or filter numbers for both digital and
film cameras. In Digital Mode, the color temperature and compensation readings
are based on human visual response. In Film mode, readings are based on the
color characteristics of traditional photographic film. By engineering the spectral
characteristics of both systems into a single meter, Sekonic designers have given
you greater control over lighting and color reproduction than ever before, regardless
of your medium.

Color Temperature Display (in Kelvin)
The color temperature is displayed for human visual response in Digital Mode or
the spectral response for photographic color film in Film Mode.
Color Temperature
LB/CC Index Display
The LB (Light Balancing) in MK-1 (Per Mega Kelvin equivalent to Mired) and
CC (Color Compensation) Index correspond to light source filtration systems.
This simplifies the selection of amber (CTO) or blue (CTB) filtration as well as the
amount of magenta or green (CC) filtration needed to balance the color of the
lights you are using.
LB/CC Filter Number Display
Used primarily for film applications, the amount of lens filtration needed is directly
indicated in both LB (Light Balancing) and CC (Color Compensation) filter values.
The display can be adjusted to read out in KODAK Wratten, LEE or FUJIFILM filter
systems in the custom setting MENU.
LB/CC Index
Illuminance Measurement
The brightness of continuous light sources is displayed in foot candles (FC) or LUX
(lx). Illuminance measurement is especially useful for cinematography, videography,
theatrical and other applications that require precise control of light source brightness.
LB/CC Filter Number
Preset White Balance / Color Compensation Function
Nineteen presets enable adjusting display values to compensate for differences in
film types, light sources, digital sensors, or personal preference. An eight-character
readout on the display allows creating custom naming for easy identification of the
compensation value.
Illuminance Measurement
Memory (Δ) Function
A simple way to observe differences in light source color or brightness is with the
C-500’s memory function. Simply take a reference reading and press the memory
(Δ) button. Then press the measuring button and measure any other light source to
see the difference in color (Kelvin or filtration) or brightness (foot-candle or Lux).

Up to nine readings can be memorized in incident or spot metering modes. An
indicator appears on the analog display each time a measurement is memorized and
the total number of memorized measurements appears numerically on the screen.
Memorized readings are retained when switching between reading modes. This
provides a fast and simple way of retaining and analyzing shadow, mid tone and
highlight exposure readings. Digital readings can be recalled and/or cleared at any
time for precise exposure control.
The dynamic range of your digital camera or film can be programmed into the
L-758CINE to create a Latitude Display that mirrors the range of your system.
This important guide will let you know when readings fit within the latitude of your
system and when they are outside the range.

Sekonic L-358 Flash Master
Cat# 401-358
The versatility of today’s cameras is expanding at an amazing rate. You can use a
digital video camera to capture still frames for printing and digital SLR camera to
record moving images. Whether you are a cinematographer, a still photographer or
involved in any facet of image capture, the Sekonic L-358 is the perfect meter for you.
Ambient Light Metering
Take readings from f/1 to f/90.0 with 1/10th stop accuracy at frame rates from
2 to 360fps. L-358 displays exposure both digitally and on an analog scale for easy
readout. Selectable DIP switches enable adjusting the aperture readout for full, half,
and third-stop increments to mirror the settings of your camera. You can change
exposure settings after taking readings and the meter will automatically compensate
to maintain the proper exposure. And the extended sensitivity range, EV−2 to 22.9
for ISO 100, allows taking exposure measurements in virtually any kind of light.
