Or are they just like colored cellophane? Anyway can we get one of those sampler packs of gels here, like a pack of 8 different colors precut for use on a flash?
colour consistency is one important factor if you are going to reuse the same settings over and often or if it needs to be replicated at will. If it's just a one time shoot for fun, I use cellophane paper over my flash.
Most colour gels aren't heat resistant anyway, I ever saw the SB800 gels got deformed after someone shot for a few hours with sucessive bursts of the stroboscopic mode.
