Rotate the exposure compensation dial to adjust exposure when photographing very bright, very dark, or high-contrast subjects.
Choose positive values (+) to increase exposure
Choose negative values (—) to reduce exposure
The amount of compensation available varies with the shooting mode.
Choosing an Exposure Compensation Value
Backlit subjects: Choose values from +²⁄₃ EV to +1²⁄₃ EV.
Highly reflective subjects or very bright scenes (e.g., snowfields): +1 EV
Scenes that are mostly sky: +1 EV
Spotlit subjects (particularly if photographed against dark backgrounds): -²⁄₃ EV
Subjects with low reflectivity (pine trees or dark-colored foliage): -²⁄₃ EV
Exposure Value (EV)
The exposure value is determined by the sensitivity of the image sensor and the amount of light to which the sensor is exposed. Doubling the amount increases EV by one, while halving it reduces EV by one. The amount of light entering the camera can be controlled by adjusting aperture and shutter speed.
