I got a book from Rosco today, well, more of a large brochure. Regardless of the size of the thing, lol, its got suggested colours for certain styles. For example, it suggests a few different gels to use if you want a daytime, mid afternoon look. Or, if you want more of a rainy day, dark sky type look. It seems really helpful. Especially for those of us who dont know these things. I realize they are only suggestions, but seeing as they come from Rosco, they must have a bit of truth in them. I'll probably keep it with my show notes stuff, so that if I need it, its there.
