pixel-hunting
n.— «he body is of course the first thing to attract attention, and it must be examined thoroughly (and here enters pixel-hunting): the main wounds, the bruises revealing that the victim’s jewellery has been taken, a mysterious powdery residue on the corpse that will need be picked up and analysed later.» —“Lost Files of Sherlock Holmes: The Case of the Serrated Scalpel” by Johann Walter Adventure Gamers Mar. 30, 2006.
