when printing images in the next supermarket I find it necessary to brighten them, otherwise they’ll be to dark. They don’t provide ICC profiles, but since these pictures are only for family and friends that’s fine.
In this context I wonder, if it’s better to use the tone curve module operating in RGB mode or the levels module? I noticed some colour clipping and shifting when using more extreme settings in the levels module, but since I only want to brighten up the image a touch I doubt this will be an issue.
Do you use either of them or maybe the exposure module instead? What do you think?
