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.
Ok so I've been using cineplus cinema picture style along side ive Lotus picture style both being a Kodak vision2 kind of in camera grade. I usually tweak them a bit in post but for the most part they are very good and quite cheap honestly but that's not what I wanted to talk about. What do you guys think about grading footage to look like 35 or 16mm film? I'm not talking necessarily "the film look" but I mean making footage actually look as if it was shot on film. What techniques do you use? Any type of workflow/grains you recommend? Is it overrated to go for this look and how often do you do this kind of grade?
Cheap CFL bulbs are convenient, efficient and economical - but they typically have a lower Colour rendering index compared to Tungsten based lights and other more expensive lighting systems.
Just how much of a difference is there?
