What is Brightness?

Brightness of an image refers to the overall lightness or darkness of the image. It is a measure of the amount of light that is present in the image, and it can affect the perceived contrast and visual appeal of the image. In image and video processing, brightness is often measured as a value between 0 and 255, with 0 being completely black (no light) and 255 being completely white (maximum light). A value of 128 is considered a neutral value, with values above 128 being considered brighter and values below 128 being considered darker.
