Specifies the level of lighting you anticipate in a scene of interest.

Lighting example: Bright
Task: Facial Recognition.

Lighting levels can vary from very dark (nighttime, indoors) to very bright (daylight, spotlight), affecting the ability of the camera to capture the image.

Lighting example: Dim
Task: Facial Recognition.

The presence of both very bright areas and very dark areas in the frame simultaneously is known as high dynamic range, and can impair target recognition, as the next example shows.
