so disregarding the differences in the smoothing/interpolation approach, the default contrast parameter is adding more regions where the tf is saturated. Like you said, things would tend to get pushed into the corners more than I’d expect. It’s nice to have the extra degree of freedom.
Clipping will do that, yes. I can add a softer contrast enhancement formula and then provide an option to switch between that and simply clipping the image.
Would there be a way to hold an unmodified version of the random tf and re-use it between invocation? Having these extra parameters has me kind of imagining something where if a particular desirable random tf is found, the user could tick a box to hold the random tf, so that the smoothing and thresholding parameters could be tuned without losing the base tf. That would be pretty dang convenient.
That would be easy; by default, the removal of the mesh (remove[1,2] where [2] is the mesh) comes towards the end of the filter but I can add an option for G’MIC to output it anyway. It can also be reused and copied in the same invocation.
