This is something I've been wondering about for a long time, but ignored til now. Another post struck up my curiosity again. When I dunk a print in the dev (using Dektol and Ilford MC III, if it matters), the sheet remains blank for maybe half a second, then the image suddenly appears. Within perhaps ten seconds, it looks under a safelight like it's fully developed, and no further development takes place (nothing gets darker). Is this normal, or is it supposed to take a full 1:30/2:00 for the image to develop?
