I am attempting to chromakey. I would prefer to spend as least as possible, and I know Ultra works well, but that is quite a bit. I have tried blankets (don't laugh) and I now have two large sheets of butcher paper in my possession of green and blue. I have a standard consumer camera, and I am wondering what the best way is to make this work. Should I do it outside or inside and should I use green or blue? If you know of any sites with a tutorial, that would help as well. Thanks.
