WHAT IS AN EV? WHAT IS A STOP?
Ev stands for exposure value. Stop refers to click stops in mechanical cameras. A change of one Ev or one stop will adjust the exposure calculated by the camera by a factor of two. Adjustments to exposure in the A, S, and M exposure modes are made in 1/2 stop increments or 0.5 Ev.
