There is no procedural Secondary Color Correction for Adjustment Layers in Photoshop, like we know it from Premiere Pro:
For years now I use different tricks to achieve secondary color correction using the mask from "color range", but this is way too imprecise and results in a static mask. It does not dynamically change when the color below changes.
So I suggest the following:
Add "secondary color correction" to the blending options (of adjustment layers). That way one can limit the effect of curves or levels to a specific range of hue, saturation and brightness values in a way that can currently not be achieved otherwise.
- "color range" is not the same because it is not dynamic.
- "hue satuaration" is not the same, because it can only affect hue ranges, but not brightness and saturation, and also it can not achieve the effect of RGB curves.
- "selective colors" is not the same, because it also has no ranges, but is fixed to specific hues and you can not achieve the effect of RGB curves with it.
