I’ve been helping a great photographer out the last couple months. He has a beautiful studio that he built himself. In his studio we have been shooting roofing tiles and electrical engineering parts among other things. Seeing how well he lights things has taught me a lot and hopefully he will continue to teach me more. His site is http://fximaginginc.com/ you can see his work and his studio there. Here is one of the set ups for roofing tiles. (sorry about the shots take with my IPhone and these aren’t in the studio)
