The challenge with the fog is the machine. The remote control’s wire is not long enough to be proceeded by you since it is mostly behind the model. So you need an assistant or to run very fast (that’s what I did). But since technic becomes a pain in the ass, it also becomes harder to focus, to compose so quick, that the smoke is still being nice and the model natural…
So, here my 20 cents tips :
1) get a longer wire/cable (dunno the right name).
2) shoot at f8 or f11 to get a bright depth of field.
3) prefocuse and lock the focus. Normally you get it done by switching the AF on M.
then you can concentrate yourself on the interaction with your model to get more than a woman with fog.
