Gamma is the relationship between the brightness of a pixel as it appears on the screen, and the numerical value of that pixel.

Cathode-ray tubes, such as a monitor screen, have a relationship between the voltage applied to them, and the amount of light emitted. The relationship follows a "power law" (which basically means it is not linear).

The numerical value of that power is what we call the gamma of the monitor or system.



Adjusting the gamma levels of a screen can have a great impact on how the object is viewed by the human eye.
