First of all, I’ve read the docs: darktable 3.8 user manual - demosaic
And, of course, I know I may select each algorithm and see how the result looks. I also understand that the default (RCD) is useful in almost every scenario.
The problem is my poorly-trained eyes cannot see difference between different algorithms.
I understand the problem they resolve, and I believe I understand what are the weakness and strengths of each one, thanks to the docs. But the results look all equal to me.
Do you have a criteria to select a demosacing algorithm? I never touch the demosaic module.
Do you have an example where is clearly visible that one option is better than other?
