Hi all!
@ JaapD
My Raw converter is Raw Therapee. Its automatic (lateral) CA correction saved an image for me which I had given up, and it has a great (manual) correction for longitudinal CA. - I was not aware of C1's automatic correction of diffraction. I think I understood that C1 has a somewhat peculiar color management, even though I don't know the details. And since RT is both very good and free, I'm not so much thinking of trying a new raw converter for the time being. Thanks for the tip though!

Yes I understand that the Nearest Neighbour was meant just for viewing. I don't scale in RT, so there should be no danger.
> Smart software can convert from a gamma adjusted space back to linear gamma, perform the deconvolution, and return to the initial gamma. That does assume proper care in the math in order to avoid cumulation of rounding errors.
The question for me is 'How can I achieve that?' RT's working space is ProPhoto. There are other choices, but I don't think any of them has linear gamma; sure is only that their gamut is smaller than ProPhotos. - Is C1 the smart software you mention?
