Your Eye's Dynamic Range

Your sensitivity is more than 1,000,000 to one, which in camera talk would be about 20 f-stops (each time you change the aperture (or the size of the hole that lets light into your camera) by one f-stop, you are letting in twice (or half) as much light). Your eye's dynamic range could exceed 24 stops, according to Cambridge In Colour. Cameras are good for 5 to 11 f-stops, with DSLRs being at the top end of that range. Your monitor may be good for eight stops, and a printers can handle a range of 100:1 or just over 6 f-stops.
