LEDs have changed the lighting landscape
in many ways—from hot to
cool, and from tungsten to daylight
temperatures. While LEDs are available in
various color temperatures including 3200
degree K and 5000 degree K range, filters
are necessary to change the color temperature
to the appropriate level. Deploying
such filters can be fairly fast and easy in
some cases, but can also slow down the
shoot in other instances, especially if the
filter or filter holder is misplaced. This is
especially true when shooting handheld
with varied ambient lighting sources, and
in run-and-gun situations. In response,
lighting companies have developed bicolor
LED lights, which can provide multicolor
lighting.
FEATURES
Litepanels’ new Croma product is a
prime example of a camera-mounted LED
light that’s designed to adapt quickly to
a variable and changing lighting environment.
The unit is a compact and lightweight
LED lighting instrument designed primarily
for camera-top use. It has both daylight
and tungsten LEDs that can be deployed
separately or blended together to achieve
color temperatures between 3200 and
5000 degrees K. This is ideal for on-therun
applications, including news and reality
TV where lighting environments can
change quickly and where there’s little
time to locate and add color temperature
filters between scenes and shots.
Croma offers a complete close-range
lighting system with either tungsten, daylight,
or any temperature of light in between.
This is all achievable at the flick of
a wrist, with the variable color temperature
integrated along with a dimming system
that smoothly adjusts between zero
and 100 percent output. And the light
provided is purportedly flicker-free at any
frame rate, shutter speed or shutter angle.
Croma breaks away from the boxy-style
camera lights that characterize many similar
units with a smoothly contoured chassis
that’s rubberized for easier handling
and absorption of mild bumps and knocks.
This also makes it cooler to the touch. The
unit accepts a variety of universal accessory
mounts for attaching to cameras that
are equipped with a standard shoe-mount.
The mount supplied with the Croma fastens
securely to its threaded base via a thumbscrew
that snugs quickly, but allows swiveling
through a range of at least 45 degrees
vertically and 360 degrees, horizontally. The
unit can also be easily mounted on a standard
light stand via its threaded base to provide
key, fill or back light. It can also serve as
an on-camera “eyelight.”
The instrument is powered by six AA
cells, which provide up to 1.5 hours of
continuous operation. The power requirement
is stated as 9 Watts, with the light
output comparable to a traditional fixture
consuming between 40 and 90 Watts. The
Croma’s LEDs purportedly have a lifespan
of up to 50,000 hours in periodic use. The
device has also been approved for use with
Anton/Bauer’s Dionic HC battery and DTap
power system.

IN USE
I first tested the Croma in shooting a series
of interviews at a convention, pairing
it with a Canon 5D Mark II. I mounted the
Croma on the 5D via the mounting post
provided, which included a swivel head.
This enabled me to use it as a key light
by angling the unit down on the subject.
I could also slightly angle it off to either
side if more of a side-lighted look was
needed. This enabled me
to make better use of
existing light for fill or
back lighting. The ability
to dial in virtually
any color temperature
opened up new avenues
for working with most
types of ambient lighting
between 3000 and
5500 degrees K, including
mixed sources.
The Croma has two
knobs on its left side as
you face the back panel.
The larger, lower one is
the on/off and dimmer
control, and the smaller
knob above it is the
color temp adjustment.
The different knob sizes
made it easy to make adjustments
without fumbling
or guessing while
shooting.
I quickly got in the
habit of tweaking the
color temperature to
match the prevailing
light between shots, and
even during shooting by
monitoring changes in
real time on the LCD
screen. For me, this turned the issue of
achieving correct color balance on its
head, as it enabled me to simply dial in the
preferred color temperature while eyeballing
the results on a monitor. I found
that the Croma has enough output to override
prevailing color balance when you’re
shooting at fairly close range.
In such situations, the Croma can be a
powerful tool for creating a desired “look”
for a given close-up shot. I found that I could
achieve a constant “look” despite shooting
in a range of hybrid ENG/EFP situations.
The Croma was up to the challenge,
including interviews done on the fly, especially
those at a close range of four feet
or less. In such cases there was no need
to match the Croma’s color temperature
color with that of existing light.
In such applications, I found myself selecting
a mid-range color temperature—in
the mid-4000s—to achieve a “warm look.”
I did this by eye, based on aesthetics—
not via color temp meter readings—and
achieved pretty good results.
Certainly, you can get consistent results
with adequate lighting with a traditional
mono-temperature camera light, especially
at close range. With conventional lights,
what you can’t do as readily though, is
tweak color to match existing lighting or
to achieve a specific look. For fast-paced
shooting at close range I found it difficult
to beat the Croma.
The main problems that I experienced
with the unit centered on power. I burned
through my fi rst set of standard AAs in
what seemed to be a fairly short time. Unfortunately,
I wasn’t able to try out the unit
with any cameras with a D-Tap option. I did
remedy the relatively short battery life by
alternating with the provided AC adapter
in situations where camera mobility wasn’t
critical.
SUMMARY
Litepanel’s Croma solves a basic technological
challenge of shooting in an urban
landscape awash with light of varying color
temperatures, as it matches to them. This feature
also facilitates creativity by enabling the
shooter to tweak the prevailing color temperature
based on aesthetic considerations.
The instrument is aesthetically designed
and rugged enough to withstand
the modest abuse associated with professional
use. It’s also well-suited to meet
the challenge involved in making the best
use of existing lighting conditions and it
allows the shooter to achieve the desired
“look” in a media landscape where this is
important. The Croma’s ability to provide
varying color temperatures makes it a
much more valuable tool than a standard
lighting fixture. Shooters who find themselves
in run-and-gun situations and who
also want to achieve special “looks” should
consider adding this light to their toolkit.
