I recently purchased a color chart to use while grading and am curious about how to treat middle grey. Intuition would tell me to place it around 50% on the waveform, and articles I've seen on the subject say 45%.
However, I know that different cameras record middle grey differently, for example, C-LOG places middle grey at 32% IRE. I haven't been able to really test it with the C100 I use at work yet, but I'm curious, when grading a C-LOG image, should I correct middle grey to 45-50% IRE, or should I leave it at 32% IRE, and just adjust my highlights and shadows accordingly?
Thanks.
