A display setting related to the brightness of the middle tones of an image. You can adjust the gamma of an image to lighten or darken the midtones (the middle-gray levels), without significantly changing the dark and light areas (the shadows and highlights).
the curve that describes how the middle tones of your images appear. Often incorrectly referred to as "brightness" and/or "contrast," gamma is a non-linear function. Changing the value of the gamma affects middle tones while leaving the white and black of the image alone. Gamma adjustment is used to compensate for differences between Macintosh and Windows monitors.
Curve that describes how the middle tones of images appear. Gamma is a nonlinear function often confused with "brightness" and/or "contrast." Changing the value of the gamma affects middle tones while leaving the white and black of the image unaltered. Gamma adjustment is often used to compensate for differences between Macintosh and Windows video cards and display.
gamma measures contrast that effects midtone grays. It is a logarithmic correction to the computer's linear representation of tone which better approximates the way people actually see dark to light tones.
(Engine) The lighting scale applied to the video output from the engine. Raising the gamma level usually results in a brighter, more luminous output at the expese of contrast. Lowering the gamma level usually results in a darker output with deeper tones.
Properly adjusting the monitor gamma insures that printed output will be of the same intensity as the displayed image. Monitor gamma can be found in the File Menu (sub) Preferences (sub) Monitor Gamma. There is also a gamma correction for each image. From the Colors Menu (sub) Adjust (sub) Gamma Correction.
Gamma is a measure of the contrast of a negative and it is symbolized by the Greek character g. Gamma is the slope of the straight-line portion of the curve. Slope refers to the steepness of a straight line, determined by taking the change in density from two points on the curve and dividing that by the change in log exposure for the same two points. Degree of developing affects the steepness, or contrast, of the curve. If we change the degree of development, the relationship between exposure and the degree of darkening also changes.
The brightness of mid-level tones in an image. More precisely, a parameter that describes the shape of the transfer function for one or more stages in an imaging pipeline. The transfer function is given by the expression output = input ^ gamma where both input and output are scaled to the range 0 to 1.
The relationship between the voltage input and the brightness of a monitor. An important factor in calibration as monitors have to compensate for gamma to get the desired on-screen grey values. The standard gamma on Windows is 2.2, and on Mac 1.8.
A numerical value used to express contrast levels in television pictures. A value of one (1) indicates a linear characteristic. Less than one indicates a curve or less contrast levels represented by a softer looking picture. The standard for a camera is .45 and for monitors is .55.
Different platforms like PC, Mac, UNIX interpret color values slightly different. An images that look dark on a PC might look bright on a Mac. The Gamma Correction is a way to explain how to an image should be displayed.

All photographs have a characteristic called gamma. The amount of gamma present in an image is measured as the contrast that affects the mid-level grays (the mid tones) of an image. The good news for digital imagers is that this gamma is adjustable by most image-enhancement programs, and you aren't stuck with the gamma that is present in the original negative or print.
The mid-tones or mid-level grays of an image. In image editing this is typically represented by a "curve" tool. The x-axis represents the original brightness values (0-255) and the y-axis represents any modifications.
The values produced by a monitor from black to white are nonlinear. If you graph the values, they form a curve, not a straight line. Gamma defines the slope of that curve at halfway between black and white. Gamma adjustment compensates for the nonlinear tonal reproduction of output devices such as monitor tubes. Gray Gamma 1.8 matches the default grayscale display of Mac OS computers. Gray Gamma 2.2 matches the default grayscale display of Windows computers.
Gamma is a value that expresses the relationship between the input and output of a device. By adjusting the gamma, the brightness of the mid-tones of an image can be changed without affecting the shadows and highlights.
1) A measure of contrast in photographic images. Film types are listed as creating certain gamma ranges appropriate to different uses. 2) In electronic color correction, the difference in the status of the color curves. The color curve represents highlight to shadow values between current values and corrected values. Changing the color curve (making a gamma correction) increases or decreases the highlights, midtones, and shadows relative to the original points on the curve.
A correction of the linear response of a camera in order to compensate for the monitor phosphor screen nonlinear response. It is measured with the exponential value of the curve describing the non-linearity. A typical monochrome monitor’s gamma is 2.2, and a camera needs to be set to the inverse value of 2.2 (which is 0.45) for the overall system to respond linearly (i.e., unity).
Informally, a measure of the brightness of mid-level tones in an image. Outside this specification, the term "gamma" is often used as the exponent of a power function that is the transfer function of any stage(s) of an imaging pipeline: output = input ^ gamma where both input and output are scaled to the range 0 to 1. Within this specification, gamma refers specifically to the function from display output to image samples.
A mathematical curve representing both the contrast and brightness of an image. Moving the curve in one direction will make the image both darker and decrease the contrast. Moving the curve the other direction will make the image both lighter and increase the contrast.
A small change in voltage when the voltage levels are low of a display produces a change in the brightness level. This same change at high voltage does not produce the same magnitude of change. The difference between what you should have and what you actually get is known as Gamma.
The exponent of the function relating output signal to input signal in video cameras and monitors. Industrial CCD cameras naturally have a gamma of 1, that is, they are linear in response. CRT displays, however, have a nonlinear response corresponding to gamma values between 2 and 3. When used together the camera may incorporate gamma correction to linearize the resulting system.
A term used to describe the amount of contrast in a picture generated from a camera. Gamma correction within a camera allows the camera/monitor system to reproduce accurate contrast levels equal to the viewed scene.
A numerical value, or the degree of contrast in a television picture, which is the exponent of that power law which is used to approximate the curve of output magnitude versus input magnitude over the region of interest.
Curve that describes how the middle tones of images appear. Gamma is a nonlinear function often confused with "brightness" and/or "contrast." Changing the value of the gamma affects middle tones while leaving the white and black of the image unaltered. The characteristics of displays using phosphors (as well as some cameras) are nonlinear. A small change in voltage when the voltage level is low produces a change in the output display brightness level; but this same small change in voltage at a high voltage level will not produce the same magnitude of change in the brightness output. This effect, or actually the difference between what you should have and what you actually measured, is known as gamma. The compensation is often referred to as the inverse of the classical bathtub curve.
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.
The range of color values a monitor, scanner, or printer can display. Adjusting this value increases or decreases the intensity of the light spectrum. A gamma corrected image simulates the adjusted display value when it is saved.
A measure of contrast in photographic images. A densimetric evaluation of graph paper indicating highlight to shadow contrast in terms of density values, plotted on a graph to establish the maximum and the minimum, the difference between them being the 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.
A numerical specification of the relationship between video signal level and image brightness. Gamma is important both in video cameras (and video encoding of movies) and in video displays. Ideally, the gammas of recording and playback devices should be identical. In practice, displays normally have to incorporate some correction to compensate for how they inherently translate video levels into light levels. Otherwise, some scenes or parts of scenes would appear darker or lighter than they should. This is especially problematic for display technologies, like LCD, that cannot produce true black. Itâ€™s hard to achieve a single gamma setting that looks right for all input signals, especially if they originate in different media (like film, video, and computer graphics).
Scanners. A mathematical function used to describe the relationship between input densities (levels) and output densities (levels.) The measure of how compressed or expanded dark or light shades become in an image.
Gamma expresses how fast Delta changes with a one-point increase in the price of the underlying. Gamma is positive for all options. If an option has a Delta of 45 and a Gamma of 10, then the option's expected Delta will be 55 if the underlying goes up one point. If we consider Delta to be the velocity of an option, then Gamma is the acceleration.
The gamma of an option measures the change in delta for a given change in the underlying. For example, if a call option has a delta of 0.5 and a gamma of 0.05, this means that the new delta will be 0.55 if the underlying price moves up by one full point and 0.45 if the underlying price moves down by one full point.
G g Seventh Letter of the Greek Alphabet. The font "Symbol" most often used on American Computers to Type Cyrillic Letters places it in ASCII 71- the space for capital "G". It looks just like an "L" flipped across the horizontal axis.
In options theory, the sensitivity of an option's price to changes in delta (delta is not constant): i.e., the second derivative of delta. This sounds mysterious, but simply results from the fact that option prices form complex curves when plotted against the price of the underlying. Defined as 2V/S2, where 'V' is the price of the option and 'S' is the price of the underlying.
Groupe AssociÈ des UniversitiÈs de MontrÈal et McGill pour l'Etude de l'Avenir (GAMMA) was an inter-university, inter-disciplinary think tank based in Montreal. Our Conserver Society Project culminated in a multi-volume report submitted to ten departments of the Federal Government of Canada and a popular book, entitled The Conserver Society [VALASKAKIS ET AL]. The major productions of our Information Society Project were the ETA Report and the TAO Report delivered to our various clients in government (municipal, provincial, and federal), in business, and in global non-government agencies (United Nations University, UNESCO, etc.). The ETA (environmental tracking analysis) Report was an account of the major processes of current change, and the TAO (Threats and Opportunities) Report was an assessment of the implications of those changes for each client.
Most common activity for a skinner is to adjust the color of an element to "just right" to achieve the desired effect. while it is possible to adjust an element's color using a graphics program, Winamp 3 allows you to link an element to a gamma control and change them in the preference menu.
The rate of change of an option's delta with respect to underlying price. The second derivative of option value with respect to underlying price. Also referred to as an options curvature. See also Greeks.

Gamma is a dynamically-typed, object-oriented, interpreted programming language that has been designed and optimized to reduce the time required for building applications. It supports the QNX/Photon and Linux/GTK GUI environments, and has a built-in library of over 300 functions.
Gamma was a band formed by guitarist Ronnie Montrose and singer Davey Pattison. They put out 4 albums, Gamma 1 in 1979, Gamma 2 in 1980, Gamma 3 in 1982 (all on Elektra Records) and Gamma 4 in 2000. Their best known song is probably "Fight to the Finish" from their first album, but another popular song was "Meanstreak".
