Color correction: neutralizing color casts
Hi all:
I’ve been learning how to make color corrections in AE in the same way I’m used to in Final Cut/Avid. From what I’ve learned, it seems that you can control contrast and gamma pretty well using just Levels, and that you use Hue/Saturation to control color. The problem is that using Hue/Saturation for, say, neutralizing color casts is kinda awkward: the way I’ve been doing it is picking a part of the image that is supposed to be white (a piece of paper, a wall), looking at its RGB values and make adjustments until the 3 RGB values are more or less the same. Basically, it’s the same process that I use with FCP’s 3-way color corrector, but without the eyedropper and the ease of use. Is there an easier way to perform this part of the color-correction process? (Of course, I could always use Color Finesse, but I was trying to do it all using just AE’s default tools).

So you made some white balance in highlights, and it’s not enough ?
Try now same process on lowest light, to get a correct black, and most important, make it also on some part closest possible to a neutral 50% grey, to get rid of midtones color cast.
If you use levels, then white balance is done with white input param for each channel, black balance with input black, and neutral balance with input gamma parameter.
Result could still be imperfect, as correction curves may request more shaping than just adjusting middle & ends points…
No particular advice for any heavier color correction plug, except the less plugs, the better, as it means each time filtering & roundingIf you really need pro color correct environment, then Shake is the perfect tool…

I know I could do it with Levels, or Hue/Saturation, but I’m just looking for a way to avoid having to “eyeball” it. Instead of going around adjusting manually the three channels until it looks right, I’d like to have a tool that allowed me to say “this part of the image is white”, and adjust the rest of the colors (more or less) automatically. Kinda like the eyedropper in FCP’s 3-way corrector.

k, in this case, there nothing else than Change to color, that is built in AE, and only with eyedropper.
It works for only one color at a time, but with tolerance settings, you can get control of what’s happening and where. For cast removal, it is just perfect…
