Dynamic Range

Dynamic Range (DR), Tonal Range, the ratio of the image brightness of the party's brightest to the darkest, he is limited on the one hand by the possibility of recording equipment (eg digital camera sensor) and secondly by the possibility of an image display device (monitor, printer). This ratio for the average matrix is 500:1 (~ 8 EV), for the printer 250:1 (~ 7 EV), and a monitor 500:1 (~ 8 EV) The approximate course, have to illustrate the concept. The values found in the real world date back to 100 000:1 (~ 17 EV) and our eye sees 10 000:1 (~ 14 EV).
