The goal of this test is to compare the latitude of these three cameras:
Red Epic, Sony PMW-F3 and Canon C300.
Red Epic recorded RAW on-board in Red Log 4K HD.
Sony PMW-F3 recorded in S-Log both in DPX on Gemini 4:4:4 10 bit and on-board.
Canon C300 recorded in Canon-Log both in DPX on Gemini 4:2:2 8 bit and on-board.
There are four tests:
1) Diffused light, from +3 stops to -5 stops.
2) Varying exposure in relation to indoor, outdoor and medium light.
3) Diffused light at 0 + spot light from 0 to +3 1/2 stops.
4) Sensors' quality test with charts.
