Understanding Camera Metering and Exposure - Photography Tutorial

Knowing how your digital camera meters light is critical for achieving consistent and accurate exposures. Metering is the brains behind how your camera determines the shutter speed and aperture, based on lighting conditions and ISO speed.

Understanding these can improve one's photographic intuition for how a camera measures light.
