The atmosphere and feeling of the shot is very important. In one particular shot (above) I have exterior air conditioners which I am using as extractor fans pumping steam into the environment.
However, it is clear that if steam is pumping out of these fans from different directions, combined with other areas of smoke within the composition (creating a smokey and mysterious feeling) the laws of physics begin to appear breached. This was made aware to me by Lead Director of Photography Michal Zagorski.
Therefore, that is why it is important to distinguish the general direction of the wind along with the force and direction of the fans. This creates a more harmonious moving image.
I do not hold footage of smoke and atmosphere which are affected by the wind, but I can use roto to simulate extinguished and parting smoke as if they were indeed affected.
Work in progress
