An army of 9mm pistol cartridges.
Here is the setup for this image:
1. Sheet of glass on top of a black shirt.
2. Room darkened, but low ambient light from a lamp in the corner.
3. Maglite (six D-cell) pointed to the left (but not at the subject) to balance the lighting.
4. Tripod-mounted camera, macro lens and long exposure.
I am licensed to possess and use this ammunition.
