Gamma Preset Mode: Basics What is Gamma?  The correlation between input and output signal levels for a camera or monitor is known as gamma. In the case of display monitors, for example, the relationship between the input luminance signal and display brightness is referred to as gamma characteristics.  Generally speaking, when the gamma curve is linear (γ=1), reproduced images become closer to what humans perceive with their eyes. Therefore, as gamma characteristics of display monitors tend to be darker with halftones it becomes necessary to alter the gamma curve closer to linear by sending an image signal with brighter halftones. This helps to convert colors more precisely, a process that is referred to as gamma correction.  In light of the fact that many studios are gradually replacing CRT master monitors with next-generation master monitors, a number of organizations (e.g. EBU, ITU-R, ARIB, and others) are announcing guidelines for nextgeneration master (reference) monitors with varying specifications.
