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.
Hi everyone, I just wanted to get a few perspectives on grey cards. I currently own a cheap Neewer card that has worked fine for my purposes so far, but I've always wondered how accurate it is. Because I intend to test some film stocks soon, I want to find one that I know is perfect. I've been thinking about getting the Kodak R-27 card, but the price tag of $27 for a piece of cardboard has made me hesitant to do so. I can't help but think that if I'm going to pay money for a reference like this, maybe I should look at other options as well. Does anyone have any grey card recommendations as well as advice on using one? Thanks.
