This is a "self portrait" of my eye that I shot while experimenting with macro with my new D600.

I used Nikon's Camera Control software to connect the camera to my laptop and used the "live view" mode to view the image from the camera on my laptop screen.

The picture was lit with an on-camera SB-800 flash with a pop-up diffuser.

The picture isn't great, but the things you can see in the reflections in my eye are pretty amazing. See the next image to see what I'm talking about.
