The off-the-shelf argument about photographic manipulation is simple. It claims that any manipulation is destroying photographic truth, severing the umbilical cord between the image and its referent, and introducing the human factor into the image's construction. This, of course, is a bad thing. How are we to believe the photograph once that delicate purity has been tainted with the wilfull, capricious, vested interests of the human subject? Of course a lot of manipulations are presented this way, but some recent work at Toronto's police dept. has created something much more interesting, saddening, disturbing and significant.
