WebWhat is the dynamic range of the human eye? When you compare the dynamic range of any camera with that of the human eye, then you can really say that the human eye has got a very high dynamic range. Our eyes are said to have a dynamic range that exceeds 24 stops. This dynamic range is calculated based on multiple situations where the pupil of ... WebVision span or perceptual span is a controversial concept referring to the angular span (vertically and horizontally), within which the human eye has sharp enough vision to perform an action accurately (reading or face recognition). The visual field of the human eye spans approximately 120 degrees of arc. However, most of that arc is peripheral vision. ...
