These were all shot on my black perspex sheet. Because of the angle that I took the first four, the surface looks light instead of dark - that's the reflection of the back-lit studio light softbox that was placed behind the objects. That also created the dramatic shadows, which I thought were quite good.
All shot with Canon 5D Mk2 and Sigma 105mm. Studio flash lights with softbox/umbrella.
C&C welcome
This one was taken at a very low angle, with the lens resting on the perspex. I used the liquify tool in CS5 for the distortion.
