A few things about cold weather photography and effects on film.

	1.  Sometimes the shutter freezes on standard 35mm SLRs
	    will freeze (open or shut), or the mirror will freeze
	    at low temps.  Keeping the camera inside the coat and
	    removing it only for photos will help; avoid exposure to
	    wind for the same reason.

	2.  At very low temperatures the film can become brittle;
	    autowinders or even careless manual rewind can cause the
	    film to split or break.

	3.  Going from outdoors to indoors to change film can cause
	    condensation on the film and spots on the negative.  Let the
	    camera come to room temperature before opening the back.
	    It might be a good idea to wait until room temp to rewind an
	    exposed cartridge (see #2).
