Shooting tips

Sometimes the camera’s exposure meter is deceived by certain conditions. Exposure compensation can be used in these situations. For example, a very bright scene, such as a snowy landscape or a white sandy beach,

can appear too dark in the captured image. Before taking the pic- ture, adjusting the exposure by +1 or +2 EV will result in an image with normal tonal values.

In this example, the dark scene appears bright and washed-out on the LCD monitor. By decreasing the exposure by –1.5 EV, the rich- ness of the sunset is preserved.

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.

Change in EV	Change in stops	Adjustment to exposure
+2.0 EV	+2 stops	4X as much light
+1.0 EV	+1 stop	2X as much light
0.0 EV	Calculated exposure
–1.0 EV	–1 stop	1/2 as much light
–2.0 EV	–2 stops	1/4 as much light
