NOTE
● EV (Exposure Value) provides an easy way to observe differences in light falling on a
scene or subject when illuminated by a continuous light source. An increase of 1EV
indicates a 100% increase or doubling of the light. Conversely, a decrease of 1EV
indicates a decrease of 50% or halving of the light.
● The relationship between aperture value (AV), shutter speed value (TV = Time Value)
and EV is EV = AV + TV. From this relationship formula, the number of ways that the
aperture and shutter speed can be combined against a certain constant EV can be
calculated.
