Output = Input ^ Gamma
When unadjusted, most CRT monitors have a "gamma" of 2.5 which means that pixels with a brightness of 0.5, will be displayed with a brightness of only 0.18 (0.5^2.5) in non-colormanaged applications (*).
Gamma settings
When viewing images on your monitor with the idea of outputting them to a printer or other output device, you should make sure that gamma settings of your monitor are adjusted correctly.

A measure of the brightness and contrast of a monitor or the midtone brightness of a digital image.
The Gamma Question: 1.8 or 2.2 ?
Gamma: if you've tried profiling your monitor or done more than just dabble in the digital darkroom you've undoubtedly encountered the term.
Some common gamma values are the following:
+ PC images are encoded at 0.45 and decoded at 2.2
+ Mac images are encoded at 0.55 and decoded at 1.8.

Gamma
Gamma is a technical term that measures the midtone brightness of a digital image.
gamma
(1) a measure of contrast in photographic images; (2) mathmatical curve representing both contrast and brightness of an image.
gamma correction
a non-linear tonal correction, editing an image gamma curve.
Gamma - If you graph the values of colors from black to white you get a nonlinear arch. Gamma is the halfway point in the center between white and black.
Gamut - Also called color gamut or color space. Complete subset of colors.
Gamma Compression
Another example is Gamma compression. I'm not Timo Autiokari, but his fundamental point that "Gamma 1 (linear) is better" is correct and supported by Giorgianni and Madden themselves: ...
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 is the setting on your computer's CRT or LCD monitor that dictates the brightness of the displayed image.

This is a process that makes pictures appear more accurately on a specific monitor via tone mapping.

gamma
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.

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
In digital imaging, the term gamma is commonly used to describe the non-linear behavior of a device’s tonal response.
gamma
If the possible values of light coming from the subject of a photograph are plotted against the values by which that light is represented in a photograph, the resulting curve is called the gamma.
Gamma. A numerical way of representing the contrast of an image. Devices such as monitors typically don't reproduce the tones in an image in straightline fashion (all colors represented in exactly the same way as they appear in the original).

Gamma/Contrast
Apply in adjustment layers (via levels or curves). Use masks if needed.
Color-based contrast enhancement can be applied using Hue/Saturation adjustment layer in luminosity blend mode.
Gamma
The contrast affecting the mid-level grays or midtones of an image. Adjusting the gamma of an image allows you to change brightness values of the middle range of gray tones without dramatically altering the shadows and highlights.
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.

Gamma: the measure of the contrast of an image or imaging device.
Gamut: the range of colors and tones a device or colorspace is capable of recording or reproducing.
Gamma
This is a term that represents a picture's contrast level. A high gamma measurement is high contrast and a low reading is low contrast.

Gamma Correct
Technically, gamma correction is intended to compensate for the difference between the way a camera takes in light and the way a computer screen displays it.
Gamma: In this context, gamma refers to the contrast of the image. The higher the gamma, the higher the contrast.

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.

Gamma - measurement used in sensitometry to describe the angle made between the straight line portion of the characteristic curve of the photograph emulsion and the base of the graph. The gamma is the tangent of the angle so formed.

Well, first of all, forget Adobe Gamma, that cheesy "calibration" program that comes with Photoshop. It's almost useless. I hate to think of all the students who told me that their system (and prints) looked WORSE after running that program.

The White Point, Black Point and Gamma are the most important sliders for realism effects. Increase Gamma to make the images look more real.
We do this with the next three sets of control: White point, Black point and Gamma. White point controls the highlights, Black Point controls the shadows and Gamma controls the Midtone.
This feature was first introduced on the Hungarian Gamma Duflex, whose first prototypes were made in 1946 and series production started in 1947. It seems that a Japanese 6Ã-6cm SLR prototype called Orchid was also tried that feature in 1946.
With Levels, you can change the black point, white point, and midpoint (aka gamma). With the possibility of doing this for each of the channels separately, this is often all the control you need.

Brightness adjusts the midtones (sometimes called gamma) to lighten or darken the overall image without affecting the black and white tones and the details they contain. By default, the Brightness slider has a value of +50.
The full range of electromagnetic wavelengths extends from the shortest gamma rays of 1 millionth mm to radio waves of 6 miles. Buried in the middle is the visible spectrum, the tiny portion to which the human eye is sensitive.
Proper understanding and use of contrast--perhaps more familiar as tone or gamma, but in any case the relationship between light and dark in an image--is essential for mastering landscape photography.
Step 2. Your scanner has to be fine-tuned to work at its best e.g. Nikon Scanners have Gamma Values. Set them as instructed to compensate for your monitor.

The 'Gamma' slider works in conjunction with 'Luminosity' and 'Black Point' and 'White Point' levels, controlling the middle range tones. I tend to end up playing with all four of these sliders at the same time until I get the right balance.
The sun is a nuclear furnace that is constantly emitting Ultraviolet rays as well as X-Rays and extremely dangerous Gamma rays. The intensity of these different rays vary according to their wavelength but they are all present.
Use the Quick Selection Tool to select the sky. Add a Levels Adjustment Layer via Layer>New Adjustment Layer>Levels. Drag the White Point slider to the left to brighten the highlights and modify the midtones with the central (Gamma) slider.

Like Paint, it can help you with your photo editing. It's able to perform basic tasks like Paint, but also lets you annotate your images as well as perform basic image corrections such as gamma, saturation, contrast, brightness and sharpness.
