Seamless paper: I'm looking for 6-7ft roll but they don't seem to exist. So I'm thinking about using 26" (~2ft) and 53" (~4.5ft) roll together and edit if needed or buy 107" (~9ft) than use some kind of saw to cut it. Thoughts? Background stands: Midwest Photo Exchange LumoPro MF613 Background Stand Kit w/12ft Crossbar Tripod: Not familiar with this. Are there any bang for your buck tripods? It will be just for the studio. Light modifiers: Are there stripbox and octabox for speedlights?
