Log C in SUP 2.x and SUP 3.x

The new Log C curve in ALEXA SUP 3.x has the following features.

• Soft-shoulder for exposure index settings greater than EI 1600.
• Fixed black level of 95/1023.
• Larger linear part of 9-10 stops.
• Wide gamut RGB instead of camera raw RGB.

The changes to the Log C in SUP 3.x have two visible results. The images have slightly more saturation and, for higher EI settings, the black is lower.
