Solution

The camera can detect areas in the scene, such as faces or backgrounds, that are too bright or dark and automatically adjust them to the optimum brightness when shooting. Also, when the overall image is lacking in contrast, the camera will automatically correct the image for a sharper impression when shooting.

Attention:
  • Screens or menu listings may differ depending on the camera model being used.
  • Under some conditions, the image may appear coarse or may not be corrected properly.
