WebYour camera, on the other hand, has a contrast range of about 12 to 14 stops, depending on the camera. In other words, your eye can see almost twice the dynamic range that your camera can. The human senses of sight and hearing have a relatively high dynamic range. However, a human cannot perform these feats of perception at both extremes of the scale at the same time. The human eye takes time to adjust to different light levels, and its dynamic range in a given scene is actually quite limited due to optical glare. The instantaneous dynamic range of human audio perception is similarly subject to masking so that, for example, a whisper cannot be heard in lou…
