Specifies the level of lighting you anticipate in a scene of interest.
Lighting levels can vary from very dark (nighttime, indoors) to very bright (daylight, spotlight), affecting the ability of the camera to capture the image.
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.
Lighting level is an obvious aspect that impacts selection of video equipment and refers to light available to illuminate the scene of interest.
Consider: What level of lighting do you anticipate in a scene of interest?
|Scene Lighting Level
|Constant Lighting - Bright
|At a comparatively bright level
|Constant Lighting - Dim
|At a comparatively dim level
|Ranges from bright to dim
