If I adjust contrast, saturation, sharpness and curves to one image is there a way to apply the same adjustments to all? I know I can select previous on an individual basis but I have to do that one by one.
Is this something that can be done with a script? or ? Can Gimp be programed to execute contrast/previous, saturation/ previous, curves/previous sharpness/previous such that one command is executed for the group of adjustments?
Contrast/Saturation and Curves, yes, because in fine all you have done is map the color of the pixel to another color and the result depends exclusively on the input color (if you didn't use a selection mask of course). So if you want to reproduce the processing all you have to do it create an Input RGB to output RGB table. This is called a CLUT (Color Look-Up table).
The GMIC filter suite can do this for you
On the first image,
- You apply contrast/saturation and Curves (*)
- You use GMIC > Colors > CLUT from After-Before layers (using the new result and the original image) to generate a CLUT
Sharpness is another story because unlike the others, it depends on neighboring pixels.
If you use heavily photo-oriented software like Darktable and Rawtherapee, they can save a "recipe" of your processing that you can re-apply on other images (and yes, they also work on JPG).
Personally, I have a few shell scripts based on ImageMagick for this.
(*) One too many here, because contrast can easily be done as part of Curves.
