Good things come in small packages, as they say. (Who are 'they' anyway?)
This resulted from messing about in the kitchen with an eggshell and some jewelry. I tried different lighting including two strobes on either side, but this got me the look I was after with a 580EX flash mounted right on the camera.
Shot with 50mm 1.4 at f4, 1/100th, iso 100, lit by one flash with a smidgen of bounce off a white card at the top of frame.
