# Exposure compensation

The exposure compensation lets you correct the exposure of your photograph based on the automatic exposure chosen by the camera. To do this, slide your finger horizontally (according to the current orientation of the device) over the camera viewfinder. You can perform a positive exposure compensation (greater than zero, that is, increase the exposure) or a negative exposure compensation (less than zero, that is, decrease the exposure).

The exposure compensation is only available in automatic exposure mode. If you set a exposure time manually the exposure compensation is not available.

The range and granularity of the exposure compensation varies with devices and camera lenses. Although a range of +/- 2 EV is typical, the range on your device and currently selected camera lens may vary.

Exposure compensation and bracketing

When using the bracketing camera mode, the range of exposure compensation will be reduced.

Examples:

  • If you have set the bracketing to take photos at -1 EV, 0 EV and +1 EV, and the usual available range is +/- 2 EV, there is only a +/- 1 EV of exposure compensation range available to adjust. If you have
  • If you have set the bracketing to -2 EV, 0 EV and +2 EV, and the usual available range is +/- 2 EV, there exposure compensation cannot be adjusted anymore.

Exposure compensation, manual exposure and bracketing

When using the bracketing mode bracketing camera mode, you can set the exposure time manually (if your device supports manual exposure time selection) to achieve the same result of exposure compensation when the full range is used by the bracketing function.

Example:

  • If you have set the bracketing to -2 EV, 0 EV and +2 EV, and the usual available range is +/- 2 EV, there exposure compensation cannot be adjusted anymore. However, if you set the exposure time manually to a shutter speed that would result in a darker/brighter image, this is the central exposure that will be used for the photo at 0 EV, therefore the -2 EV and +2 EV will be relative to that central exposure set manually.
