A useful feature on most wirelessly controlled flashes is the ability to assign them to groups. For example, you can put a flash in group A, B or C.

Divide your flashes into groups


You only need to do this once, in principle. You could stick a label with A, B or C on your flash, for example, or use coloured labels so you can recognise them quickly. That way, you immediately know which group you are holding.

You can then set the different groups independently from the trigger on your camera. So you could set group A to ½ power, for example, while using group B at 1/16th power.

I use group A as the main light, B as the hair light and C as the background light. I rarely need more than three groups, but it is useful if your flash system supports even more groups.
