I'm with Steve. $30 and an hour's work can give you a 6x6 or 6x8 diffusion panel. Some PVC pipe and corners, some glue, and you've got a frame (under $10); 3 yards of cheap wide *white* muslin, and you're ready to go. (Much more durable is nylon ripstop, but it's a little more expensive. Or if you don't sew, make the frame the same size as a commercial frame and buy the fabric; it's usually not that expensive.)(posted 8754 days ago)Then blow another $20 on a few rolls of film and see if it'll give you what you want.
