Alright, I was looking at a few photography tutorial sites, and a lot use these photoflex discs and other manual lighting techniques. And I was wondering if anyone here uses these? Also, this photoflex stuff just looks expensive (being as they hide their prices on their website) and was wondering if there where less expensive alternatives. And I'd even be up to hand-fashioning my own if I had the right things to do so. So I really just want to expand my knowlege with the whole lighting thing. Hope I made sense in all that! Thanks.
