Thanks Markus and Marie-Noëlle. I am learning quite a bit! One last question. How can I find out which values are applied by default in the sharpen and base curve modules? Or more generally, how can I re-apply the default presets? For the base curve module there are a "canon eos like" and "canon eos like alternative" presets, while for the sharpen module there is a "sharpen" preset (I have not created any preset of my own). Are these the ones that get applied? Thanks again,
