Off-camera Flash Basics
wireless
ratio control
The light ratio represents how much stronger one light
source is compared to another. A direct light source
could be twice as strong as that same light from a
reflected surface. Therefore, we would have a 2:1 ratio
of direct light vs. reflected light.
Wireless Ratio Control allows us to control the volume
of light that is emitted from each flash or set of flashes
wirelessly. Each set can include more than one flash.
This is easy to do and allows us to set the ratio of the
control flash on the camera plus two more flashes or sets
of flashes. Being able to control all of our flashes from one
source saves time while also allowing for more creativity.
What is it?
Dynamically control the volume
of light that is emitted from each
flash in a multiple light setup.
How to use it?
Set all your flashes in wireless
mode (WL). Set your flash on
the camera to control (CTL) and
the other flashes to one of the
wireless zone settings (RMT1 or
RMT2). Then set the Ratio Control
in the “control” flash settings.
Here you can set the ratio of
the control flash on the camera
plus two more flashes or sets
of flashes. (Refer to Instruction
Manual for more details)
Where to use it?
Use this when you want to control
the amount of light emitted from
your wireless flashes.
Final Shot
In this three flash setup, we want to add some
dramatic lighting to the subject’s face. We could
move one flash further or closer to the subject
adjusting the amount of light hitting one side
of her face but that would be cumbersome.
Instead we used Wireless Ratio Control from the
flash on our camera.
F7.1, 1/160 SEC, ISO 125
02 Camera Right Full
With the flash off behind the subject, we
focus on setting the two flashes slightly
in front and on each side. Here, the right
flash was set to a ratio of 8 while the left
flash was set.
01 Background
A flash is placed 14ft away to illuminate
the water behind the subject and is
controlled from the secondary remote
channel of the flash–RMT2.
03 (1+2) Left/right balanced
Two flashes are 6ft away on each side of
the subject. Here is the result of all three
flashes firing at equal power of 16.

Getting Creative
Because we were able to change the
Flash Ratio from our on camera flash
we were able to quickly experiment with
different ratios until we achieved the
desired result.
