Mask
Mask function is very useful for high-volume product photography,
where you often want to mask out the background. If you define your
key lights as one group set to n1 (1th flash of trigger), and your
background lights as the other set to n2 (2nd flash of trigger). All lights
are set in M mode. Successive presses of the shutter will fire a
different group of lights each time. You'll get a shot of the subject, and
then get a white-background/black silhouette shot, perfect for defining
a mask.
If you don't want to use MASK function, please set to <of>.
Setting ID Number
Transmission ID number is selectable from 1 to 30.
Note: In order to achieve effective trigger, the ID number on flash light
and transmitter must be the same.
