Modern digital cameras may rival the human eye's perception of color and spatial resolution, but they cannot yet match the eye's ability to manage contrast. An image sensor or display medium's contrast ratio defines the distance between the darkest black and the lightest white that the device records or displays. The eye's contrast ratio of 1:100,000 is roughly 24 times greater than the 1:4096 of a typical digital camera. As a result, even in correctly exposed photographs, shadows are often too dark and highlights too bright, creating a noticeable loss of detail.
