If you are like me and you gel your flash a lot, then you probably get a little frustrated when trying to change gels. I looked at several gel holders for my flash and the problem that I always ran into was that it took two hands to change a gel which left no hands to hold the camera. So, I started making B.U.G.s. Booray's Ugly Gels may not win any prizes for design but they do the job for me better than any other gel holder I have seen.
To see the effect that the B.U.G. has on images, just look at my website. Almost everything on there was shot using a B.U.G.
