Tom Furlotte Memphis, Tennessee Determining the exposure for a particular film requires the photographer to make some basic determinations about the image. The most basic is called the Sunny 16 rule. It says that the exposure for a subject in bright sun is f16 @ 1/ISO, e.g. if using 100 speed film f16 @ 1/100. For subjects in other daylight levels the guidelines are: Bright Sun (strong shadows) f16 Hazy sun (soft, but distinct shadows) f11 Cloudy Bright (can locate sun) f8 Overcast (cannot locate sun) f5.6 Dull (storm clouds) f4 You don't need a meter to take well-exposed images in sunlight if you follow the Sunny 16 rule. This rule is also how light meters are calibrated and can be used to double-check your meter for accuracy. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
