Take this simple and basic quiz to find out how much you know about photography and if … Sun Jan 25 2015 00:00:00 GMT+0530 (IST) · The total luminous intensity per square meter is measured in nits. (1 nit = 1 candela/sq. meter). A 300 nit laptop screen with about 600 cm^2 of area would yield = 300*0.06 = 18 candela. Summary: Candela is the standard SI unit for measuring the intensity of a light source for photography. In Digital Photography ISO measures the sensitivity of the image sensor. The same principles apply as in film photography - the lower the number the less sensitive your camera is to light and the finer the grain. Higher ISO settings are generally used in darker situations to get faster shutter speeds There are many different units for measuring light and it can get very complicated.
