Cake/cookie decorating candies/sprinkles are brightly colored, inexpensive and come in vast quantities. This makes them useful for macro photos and in this case, I was using them as a subject while evaluating the very-useful Rogue FlashBenders.
I placed the candies in a small plastic cup and tipped them over on a black back-painted glass desk. A Canon 600EX-RT flash fitted with a Rogue FlashBender Softbox was positioned on both sides of the candy and a third flash and softbox was used on-camera for fill. A piece of black velour fabric was draped over a box sitting on the desk in the background.
This example also shows the shallow depth of field delivered by f/2.8 on a 105mm macro lens.
