The numbers to the left and right of center tell you how many stops — or levels of exposure value (EV) — you are away from the center. As you know by now, negative numbers indicate values that would underexpose the photo.

a technique for adjusting the exposure indicated by a photographic exposuremeter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image.
