Oh, but it does. I know photography teachers who use this exercise as the first on in practical photography.
Listen up, Mikey - this is your first lesson. Both images will be exposed wrong: The black door will be overexposed. The meter just "believes" there's no light. The white one underexposed. The meter will believe ther's a lot of light. Even though both doors are photographed in the same light!!! They should of cource be exposed using the same EV. This is the reason that it's very educating to learn how to use an incident light meter, which meters the light falling onto the subject - not just the reflected light. All biult-in camera meters meter only the reflected light. This means the photographer has to add his/her own evaluation before pressing the shutter release: Plus (+) correction for backlit scenery or a very bright sky, window etc.. Like landscape photography. Minus (-) correction for a dark background - like concert shots. The lesson to be learned is also that correct exposure (in fact doesn't exist) is the photographers choise. How does the subject differ from the normal "18%-Grey", that all meters are calibrated to (re)produce? The purpose is to make the best technical use of the film or the sensor as possible in order to reproduce as many shades of the subject as possible. If yopu don't wnat that in the final picture - use your darkroom or the computer to reach what you want. It's a good idea to shot and develop black and white film if yuou wnat to get the grip of exposure. Nest lesson will be about the Zone system!

No, it makes sense to learn about exposure, it just does not matter in that example. :) ----- Original Message ----- From: "Jens Bladt" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, May 19, 2005 3:15 PM Subject: RE: Understanding exposure?
