I have done photography in a professional studio for a few years now. I am wanting to start doing some work on the side now out of my garage, not to mention doing pics of my own family. I am using an Olympus E-1 and a Konica Minolta 5D. I have been doing photography outdoors of my kids, but since we are converting our garage to a studio, I need info on indoor lighting. I am on a fixed budget however. Any suggestions?
