A very simple commercial, after a series of beauty shots of the
model in different pairs of specs the camera tracks towards her
and the specs change into sunglasses as we move.
The look was to be a very gentle, soft beauty type shot so I used Cooke's with '45 and huge soft sources.
Using a mobile motion control rig we shot a move in to a close-up
from a mid shot then change the specs for sunglasses and repeated
the move. Our model couldn't hold her head still, we tried braces,
we tried clamps, I wanted to use 2 * 4 & 6" nails but was
overruled.
We had a video assist overlay rig and in the end we showed her a
reversed image of the live picture overlaid over a replay of the
bought previous take and had her move her head into the right position.
It seemed like a good idea but wasn't working with mixes or splits.
Only when we started to switch between sources at high speed did
she manage to register her head position. It gave her a serious
headache but hey, it worked.
