Turn photo negative to positive image.
#3
There is a recent GEGL filter Tools -> GEGL Operation -> Negative Darkroom with some settings for these negatives. (had to trawl for this example)

   

The problem is getting decent back lighting, I have some success taping to window with a-sort-of-diffuser backing. Must try ofnuts tip about using a phone display for lighting.
