Dynamic range is the range between the brightest and darkest detail that the eye can discern.
The human visual system can generally perceive a dynamic range of about 160dB overall.[1]
Dynamic range is affected by chemical changes in the eye and iris changes. Chemical changes happen on the order of minutes, and iris changes happen almost immediately.[2]
The instantaneous dynamic range of the human eye is about 10 stops, or a contrast ratio of about 1000:1.
