Just a quick tip if you do a lot of product/small object shots and want them on a seamless background. Instead of rolling out a whole huge backdrop, just use a piece of matboard. If you do your own matting/framing, you’ve probably got some on hand. It comes in nice 30″x40″ sheets, and it is rigid enough to stay in place on it’s own when propped against a vertical surface like a wall or chair pushed up agains a table. It gives a nice smooth curve under it’s own weight, and provides a non-wrinkly insta-seamless-backdrop. and when you are done, you can mat your pictures with it
