Understanding The Exposure Triangle

A perfectly exposed photograph is a thing of beauty. In the old days that meant carrying around a light meter the size of a hand grenade and taking readings to calculate the exposure. Because those calculations were frequently average values, a smart photographer would bracket exposure by a stop above and below, hoping one of them was just right. Trying to get the exposure just right in the shot above with a hand-held light meter would have been as much luck as skill.
