I'm an engineer with a large defense contractor. I live in Littleton Colorado, and shoot with a Canon 20D. For lenses, I use a Canon 17-55mm F2.8, Sigma 50-150 F2.8, Sigma 100-300mm F4.0, and a Sigma 105mm F2.8 Macro. I shoot only RAW (plus the small jpeg, for quick previewing), and uses Canon's RAW processing software to edit my photos. I also use an old version of photoshop, but I prefer to stick with whole-image editing operations, rather than get silly with fancy Photoshop trickery. I'm a photographer, not a graphic artist!.... although I have been guilty of taking out the odd powerline, or telephone pole.
