momentum

@vasa: Thanks Vasa:-)
I had two light sources. Obviously the slow sync flash, and in addition to that a halogen spot just above the item.
Actually the set was made on my dinner table, and I spent approx. five minutes on the shooting and ten minutes on the digital enhancements on "Newton" and "momentum". I'm very surprised over the reactions on these photos, since I did not put all that work into it. I was just lucky I guess.
On other occations I can go around for days, trying to figure out how to take the next shot. If I'm not happy with a picture, it won't go near Aminus3 at all.
