Frames from a corporate video about safety systems.
Shot on 7D. The request was to archive an unnatural electric blue iris that lights up batting an eyelid.
I had to do very accurate masks to isolate the iris.
In the second frame you can see a bright shot graded to looks very dark (it lights up at the end of the clip).
