I have found some scans (tif files) and i would like to try to edit them with art. Made iirc with Nikon Scan. They open fine for example with geeqie and gimp, not with art.
What exactly is the problem with ART? Doesn’t it show the file in the browser, does it give an error message, does the image look wrong - probably all white, it that’s the meaning of your headline?
