I have recently acquired a Polaroid 250 and am having problems with exposure. All three shots I have taken with it so far have been underexposed, although setting the light/dark dial two notches to lighten has helped somewhat. I'm using Fuji FP-3000B film, and have put in a brand new battery (which tested fine). From what I've read the photocells in these cameras deteriorate over time, necessitating the need for some form of exposure compensation. I have found a link to a repair procedure (which I am assuming would allow me to use the light/dark dial normally and get good exposures), but it is dead. Does anybody have a repair procedure for these cameras? The original page was located here: http://home.comcast.net/~jrpalma/pack_repair_exposure.html.
