Dynamic Range

In photography, dynamic range expresses the ratio between the maximum and minimum amount of measurable light intensities, which is essentially just white and black. A stop is something that is either doubled or cut in half. For example, one stop up is to double and one step down is to half. The best digital cameras out today can capture ten to eleven stops. Negative film is able to capture nine to ten stops, while when converted to positive it only has five to six. However, our eyes are able to perceive ten to fourteen stops of light.
