Digital camera in the sensitivity and exposure value, what is the difference between the two parameters?
Where N is the aperture (f value); t is the exposure time (shutter) in seconds.
The exposure value is a logarithmic scale system with a base of 2.
ISO calculation formula for the H * S = 0.8 (S sensitivity, H for the exposure), exposure value (Exposure Value, commonly known as EV value) on behalf of the same exposure can give all the camera aperture shutter combination.
The higher the ISO value, the higher the sensitivity of the sensor.
Sensitivity, the English name ISO, ISO in the digital camera that CCD or CMOS sensor photosensitive speed.
