UNDERSTANDING GAMMA CORRECTION
Gamma is an important but seldom understood characteristic of virtually all digital imaging systems. It defines the relationship between a pixel's numerical value and its actual luminance.
gamma correction
a non-linear tonal correction, editing an image gamma curve.
gamma curve
the shape of a line connecting the input and output values responsible for generating an image.
Gamma Correction or Gamma Compensation - The process of preconditioning or adjusting an image to correct for the gamma of the device used to reproduce the image, such as a printer or display screen.
gamma correction:
This is a process that makes pictures appear more accurately on a specific monitor via tone mapping.

Gamma Correction. With reference to displaying an image accurately on a computer screen, Gamma correction controls the overall brightness of an image. Images which are not properly corrected can look either too dark or bleached out.
gamma correction
Used to calibrate devices, smoothing out any irregularities between input and output signals.

Gamma correction. A method for changing the brightness, contrast, or color balance of an image by assigning new values to the gray or color tones of an image to more closely represent the original shades.
Gamma correction
A process whereby contrast values are optimised.

Gamma correction
The measure of contrast that results in lightening or darkening the midtone regions of an image. Also, the amount of midtones need to be adjusted on a monitor.
Gamma Correction
Often refers to the accurate display of an image on a computer screen. A good image may look very poor on a screen with incorrect gamma adjustment.

A Gamma Correction, also known as gamma nonlinearity, gamma encoding or just gamma, refers to a nonlinear (logarithmic) equation that encodes or unravels the intensity of light in still photos or movies.
The gamma correction applied to a computer monitor that describes the relationship between input voltage and output luminance.
Gamma or gamma correction is a non-linear operation which is used to encode and decode luminance or color values in video or still image systems.

Applying a gamma correction of 1/2.2=0.45 will allocate more tones to the shadow areas and fewer tones to the highlight areas in line with the characteristics of our vision. When working in a gamma 2.
This gets complex fast when you start taking gamma correction, scaling and everything else into account. These are beyond the scope of this article.
A numerical value used to indicate the non-linear response curve of an output device to light intensity. Used to correct the intensity of an image on a display device (gamma correction). Also called gamma value.

This process is known as gamma correction and it ensures that camera and monitor working together produce a linear effect.
If new, you should have a handbook with all the monitor's specif ication. Depending on the software program you use, there are different ways to achieve the some goal e.g. Photoshop 4 has Gamma Correction.
