Tips for JPG images

JPG compression adds faint blotches around edges. The speck filter merges islands smaller than the chosen size into their surroundings.
Fewer colours give cleaner shapes. Start with 3–4 and add more only if a detail goes missing.
Photos become poster-like flat areas. For a shaded picture, a lithophane is the better technique.
