Since I’ve been shooting more with a flash, I’ve realized the importance of gelling your flash. You can buy little strips of gels to put on your flash to help balance out unwanted color casts from the existing ambient light.
I’m planning on making a tutorial about how to use gels on your flash so I won’t get into too many details here. To make the gel holder, I took a piece of transparency paper and formed it into the desired shape. The small piece that’s jutting out from the back can be inserted into the top of the flash (or held to the flash via rubber band) and viola, instant gel holder!
