So I'm looking at getting a 3rd ring light. This time I'm looking at a 6" light for some of my macro work. I've found some good ones on amazon that I'm debating on. But I'm also looking for some color filters to go with it, a few came with my mini and I've got some (and can get more) for my large one. But for the life of me I can't find them for a 6" model, do they make them? If not what's the best way I could maybe make my own?
