Making nice photographs when all you have for lighting is a bunch of tungsten shop lamps can be a real challenge. It is particularly hard to photograph polished brass under these conditions. So this weekend I set out to build a flash diffuser to improve the quality of the photography on this site.
Most of the diffuser is made with foam board and packing tape. I laid out a square 30″ inches on a side and then drew a cut line from each corner to the center of the top line. This gave me two right triangles that when taped together matched the center triangle.
