It'll be a cloud of fairly dense smoke. Won't that obscure whatever it is that you're trying to photograph?
I think I will have to experiment a little once I have found several options that look likely. The hope would be that if I can move about with the smoke in my hand and leave it a few seconds, my model can step in and my camera and lights would be ready to go. I don't want a thick covering, so the smoke has to be heavy enough to hang in the air a little, not for long just enough to fire off a couple of shots.
As I will be using flash in the distance the effect of the smoke doesn't need to be that thick, but it does have to cover the whole area. The flash guns will light up the smoke (I hope!) and create a dramatic background to set my model in.
I can see my self wasting ££££ on over priced retail smoke bombs here, I was hoping I could find some kind of trade supplier.
Cheers
Cris.
