First time I was reading about camera tossing in one of the topics of the budapest photobloggers forum. I thought I have to try it too but I was not brave (or crazy?) enough to throw my D70 up in the air, so I was only spinning the camera using the neck strap in front of two light sources in a dark room. Anyhow, I like the result.
