I do a lot of product photography and there are two places I go to when I need to prepare supplies for a shoot: one is the hardware store to get some tiles and the other is our local bookstore/art/office supply store.
Based in San Francisco, Kim Pimmel is a photographer, a user interface designer, a DJ, and a "maker." Take a look at his experimental light painting photographs, and you'll see each of these interests shining through. Pimmel has spent years experimenting with long exposure photographs that show different light sources as brushes. His beautiful images are created using custom rigs and common objects -- things like turntables, ping pong balls, fiber optic cables, pendulums, iPhone screens, and more.
