On the left we have Anna and Josh checking some tester footage before of same action as the smoke running but we did the tester without smoke so that we didn't waste any that wasn't needed. as you can see from the pictures below, the tester was correct and we did the shot but with smoke.
On the right we have the team checing the real footage of the running through smoke scene to make sure that it was what we needed and to see if we could improve it in any way.
Finally above, we have us checking some more footage again from the smoke running scene, this camera though was at waist height so the actor is running towards the camera. This is the same shot as above just from different angle to show fully what we were doing which is looking at the footage.
