Color Correction Question

[Chris Smith]

Well a stop is either half or twice as much. So if you did an overall brightness adjustment, drop the value by half.

If you are using levels, it’s not so cut and dry because it depends on how you want it darkened. Do you want to drop the gamma? Crush in the blacks?

Why do you need to change it by exactly by a stop as opposed to what looks good?

I usually use levels for my color corrections and I go for what looks good, having done that, when a supervisor/DP looks at a plate with a color correction applied to it. They like the plate lets say, but then will ask to take it back a stop, (keeping in mind that the supervisor is coming from a tradtional photo background). I can drop my gamma by half or double, etc, or another situation might be if I need to wedge a plate and I can drop the “exposure” by stops or half stops. I guess my question is mainly out of curiosity as to whether there is something such as a levels that works in stops? I know eLin has an eWedge effect that works in stops for wedging, provided you are in eLin space.

thanks for the reply

That might be a good feature: a “units” switch, sort of like RGB vs. HSL. Sort of.

If you think in stops, it could allow you to work more quickly and intuitively.

Actually, I think that’s what Au Naturel’s exposure plugin does:
