O.k. So I've realized that I need a choice in backgrounds for my living roo---I mean home studio. The white walls of my home are killing me. It's like shooting a big diffuser. Good at times, not at others. So I figure a decent background stand and some paper rolls would good to have. I can move between black and white, etc. Looking around, it seems there are a lot of choices for stands and a lot of choices for backgrounds. Any hints here? I'm thinking I need a 12' wide setup ideally. But do I have to worry about getting stuck in a proprietary system or anything like that?
