I'm a photography student living in the dorms (and maybe soon, a not-much-bigger cheap apartment), and I'm pretty serious about photography (leaning towards portrait/studio work, I think). I'm throwing a Portrait Party in my residence hall at the end of March, and I'm wondering about equipment. Should I go down to Walmart, buy a white and a black bed sheet and some dowels, sew the dowels into the bed sheets for weight/straightness, and use those for backgrounds? Or, should I buy a Collapsible Background like this one? I'm pretty sure that if I bought the background I would get LOTS of future use out of it, but it's almost twice what I'd expect to spend on a DIY solution. Thanks in advance for any advice!
