Hi everyone. I'm very interested in being able to breakdown lighting ratios from inspiration using the same set of standards that I use when shooting (mapped IRE false color values on a production monitor). However, I'm having a bit of trouble grasping the best way to accomplish this. It's clear to me that images read best on camera between 2 stops over/under key. I'm shooting in slog3 on FS7, but monitoring in rec709 LUT on my monitor. I've brought up a chart from the app "LutCalc" that displays relative IRE/stop values for a certain monitor LUT- in this case going from slog3->rec709(800%). (Attached) So from what I understand here are the following values for +- 3 stops from key. -3 = 14% -2 = 20% -1 = 30% 0 = 44% +1 = 63% +2 = 84% +3 = 97% Does this mean that if I assign each relative stop to the corresponding IRE value in False Color using the same monitor I shoot with that I will be able to accurately breakdown lighting ratios and seamlessly recreate said ratios on set by matching colors?
