Yellow/Green Skin with A7S Slog2

Recommended Posts

Using picture profile 7 on the A7S uses Slog2 Gamma and S-Gamut Color Mode. This can result in green/yellow splotches on skintones after converting Slog2 into something that looks close to Rec709. WB settings in camera or after correction in post don't appear to matter: only certain shades of skintones have the color issues. While this can be fixed with qualifier color range correction tools, that's a lot of extra work. I found that changing the Color Mode to Cinema appears to fix the color issue (Pro Color Mode also looks pretty good). It's not clear how this might affect dynamic range (figure primarily related to gamma/luma), as that's a major point of using Slog2, however so far the results look pretty good.
