Exposure value converter
Convert exposure value to lux, to a shutter speed, to an aperture, or to the plain number of times more light. Every step of one is a doubling.
That's about the same as an overcast day. That is about 4,096 times the light of EV 0.
What it means
How much light is that?
All values are at ISO 100. Shutter speeds assume f/5.6 and apertures assume 1/60 s, since EV fixes only the combination, not either one alone.

Three things worth knowing
-
Sunny 16
In bright sun, shoot at f/16 with a shutter of one over your ISO. That is EV 15, and it works without a light meter anywhere on Earth.
-
One number for two dials
EV was introduced in the 1950s so a meter could give a single number, and the photographer could then pick any aperture and shutter pair that added up to it.
-
EV is not a setting
It describes an amount of light, which many camera settings can capture. "EV compensation" on a dial is a different thing again: it shifts the meter, not the scene.

About exposure value
An exposure value is a way of counting stops of light. EV 0 is one second at f/1.0, and every step of one either doubles or halves the light, so EV 15 is thirty-two thousand times brighter than EV 0.
Because it is logarithmic, it compresses the enormous range from starlight to a sunlit beach into numbers you can hold in your head.
