I thought I'd post a couple of still images I set up in my office with 2 pieces of black foamcore, and 2 pieces of white. These are not corrected in any way. Just straight out of the camera with no filters.

Lighting was existing overhead office Flourescent lighting (the ugly stuff).

Shots were at 1080/24p. Iris was wide open.
Meter shows 14 FC
Shutter was 1/48
Gain set to zero. Normally I shoot at -3 but there wasn't enough light.

Enjoy!
