Avoid direct sunlight when unloading the film Keep your exposed cartridges in a cool dray and shady place and have them processed as soon as possible Do not leave the same roll of film in your camera for months on end, since black and white film may become fogged and color film may experience a definite color-shift
The Variable Aperture AE control will not operate, but you can manually adjust the aperture ring of the lens. A basic exposure guide to follow for bright sunlight (with distinct shadows) is to make a fraction representing the shutter speed needed at f /16 by putting a "one" over the film's ASA rating. With a film of ASA 100, use 1/100 sec.
