This is something I have wanted to try for a long time. I started with a black backdrop, piece of glass, and a single SB-600 off to the left side. Even after adding a reflector to the right, the light was not being distributed the way I liked it. I turned off the flash and used incandescent light. Once the light and reflector was set up it became a chore trying to keep the dust off the glass. I thought I had got it all and found out later in post that I still missed some. The photo has been touched up to remove the dust that was only visible when the flash fired.
