I just tried a simple test I think this is not true. Try this: - take one picture, set sharpen to maximum settings and export to half the size - now turn off sharpening and export to half the size - now go to this last small export, the one with no sharpening, and open it - now set sharpening to maximum settings and export again with no up/downscale Now compare the first and third export. For all those suggesting alternatives: of course I could use gimp, lua scripts, DT again, imagemagick or RT or I could go to my friend and do this with Photoshop, why not. But this does not make any sense to me. I know of no other program where I have to do this extra steps of post processing for downscaled exports, not an uncommon thing with modern sensors. I do not get why downscale is not handled as a normal hidden module and placed in the pipeline at a reasonable place. If this is a problem, adding another "post-processing" smaller pipeline could be a reasonable alternative? Often I do not have time for these extra steps, so I just do one export and my shots are dull. Consider all the users that are not aware of this problem and they get a bad output from an otherwise great program. There are also smaller problems: when I do the first export I use the "title" and "rights" tags to create the filename. When I reopen the files with DT and do the "after-sharpening" export I need to remember to change the filename to just FILE_NAME or these are appended once more. Of course, as I do, I can create a few export presets pairs, one for the first export and one for the second, but these are a lot of extra workarounds and I often forget to switch back and forth.
