>>4488728clearly no /mu/tants in this thread, its the cover for the album Wildflower by the Avalanches (not nearly as good as Since I Left You btw). wiki says the cover photo was taken by gen kay
https://genkay.com/ and their website offers few clues other than that they pretty clearly work with both digital and film. I'd reckon on it being film based on the grain, as well as the aesthetic of the artist they were doing the work for.
