also photographers. it's the easiest way to get a clean display for a lot of picture files without importing/opening up another app. just select the files, hit space for quicklook, and go full screen.
yeah quicklook is great (which is the regression in the linked article is very disappointing). not even just for photos, the video preview and trim functionality is great!
although apps can integrate with quicklook (eg vscode/textmate for code files), there are some files that should be previewable but isn't, like animated webp or webm files.
