50mm lens reversed on body
I'm lighting the subject with two bright fluorescent lights clamped to my workbench. I've got a piece of black (not really black, unfortunately) card stock propped up behind. The camera is on a tripod. To get maximum depth of field, I'm not opening the aperture at all. Hence the long exposure.
This is a nice trick ($10 macro lens!), but the depth of field is so narrow that all of my energy went into just getting a usable shot. Trying to compose a nice photograph would be exceedingly hard this way.
