Nice effect, you can just see the string you used to pull the dice out mid exposure. However the dsk shaped playing card does gives the feeling of a spotlight.
Oh, I like it! Nice use of long exposure and great contrast between Black and White. Now I need to go and practice! OK, one thing I would have changed is to keep the dice on the coster a little longer so they are more defined and not as transparent. No worries, great shot.
Cool effect (and tough with basic editing), but isn't the top of the dice (10) what you're supposed to consider? I suspect that your score will take another hit for shooting a "picture" of seven rather than seven objects.
Nice idea, but I don't see why you added the motion trail. It would have worked better if the dices were solid. How'd you get that circle? I've never seen any round cards :)
