Yeppers...Ysarex has it right...take the camera into TOTAL darkness...a window-less closet at night, or an apartment bathroom that has no windows, etc..,some place like that...stuff a couple towels into the bottom of any door cracks, maybe put the camera inside of a zipped-up jacket, and then throw a light-tight, tightly-woven fabric type of blanket over yourself--in the darkened room. We mean that kind of ****total***** darkness. Otherwise, the film will fog.
If you can see a white sheet of paper in front of your face after 5 minutes in "the dark"...then it is not in any way total darkness. Gotta be utterly,totally free of light. No photons!
Press the rewind release button on the bottom of the camera, and by hand, spin the film cartidge spool's nub end...and wind the film back into the cartridge, then take it to be developed.
