Very nice pictures posted here, but seriously, I know how much time this can consume does anyone here work for living? lol
One of these days, I'll try rigging up a setup like yours, but for now I settle for adequate, which means what can I do in as little time as possible. I use a Nikon 4300 in closeup mode. It was inexpensive and because at the time, it was one of the few digital cameras that could actually autofocus as close as 2 inches. I prefer natural indirect sunlight. I step outside, hold the coin up and snap a few pics, then pop the datacard, slip it into Mac and suck the pics into iPhoto. Voila!
