Re: Curves are hard to use - a couple of basic points
In reply to Charles2, 7 months ago

Curves are designed to be used to alter tonal contrast rather than color. If you use curves on an RGB image both color and cotrast will be affected. To adjust contrast only, which is the point of the tool, either convert the image to Lab mode and select only the L channel to apply a change with the curves tool, or, duplicate your RGB image into a new layer and set that layer to "Luminosity" then apply a change in contrast with th curves tool. Either of those methods will adjust contrast without altering the saturation of the image.
