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
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
Measures the contrast that affects the mid-level grays (midtowns), which can be adjusted without significantly affecting the shadows and highlights in an image

(1) In photography, the degree of contrast in an image 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 curve 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
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
The measure of change in the delta of an option compared with a price change in the underlying See Delta
Gamma is a measure of contrast in an image, typically in the midrange grays (mid-tones) Many image editing programs express gamma as a curve which can be manipulated by moving points to change the contrast of the image Adjusting the gamma allows you to correct mid-tones without noticeable changes in the highlight and shadow areas Gamma is also the way the brightness of an image is interpreted by computer hardware Many monitors and graphics cards let you adjust the gamma level to alter the monitor appearance or to compensate for brightness or color in a room This is one reason why the same image may look very different on two different monitors

The sensitivity of an Option's Delta to changes in the price of the underlying contract A measurement of how fast delta changes, given a unit change in the underlying futures price
Simply, the units in which magnetic survey maps are often contoured 1 gamma = 1 nanotesla A unit for stating the magnitude of the magnetic field vector B represented by the number of lines of induction passing through a unit area perpendicular to the vector direction 1 gamma = 10-5 gauss = 10-5 lines/cm2 = 10-1 line/m2 = 10-9 weber/m2 = 10-9 tesla = 1 nanotesla
A measure of the brightness and contrast of a monitor or the midtone brightness of digital image Adjusting the Gamma slider within an image-editing program will adjust the midtones while maintaining detail in the highlight and shadow areas Adjust the monitor gamma to make the image appear more natural to your eye A setting of around 18 is right for a Mac monitor while a 2 5 setting is more appropriate for a PC
The rate at which a delta changes over time or for one unit change in the price of the underlying asset
A class of proteins in the blood, identified by their position after serum protein electrophoresis. The most significant gamma globulins are antibodies
The lactone of 4-hydroxybutyric acid; A colourless liquid used as a solvent or reagent in various industrial uses, as well as a recreational drug. Abbreviated to GBL
A flash of gamma rays that seem to originate from a random point in the sky; their most likely sources are believed to be supernova explosions of a very massive stars and mergers of neutron stars
A correction to the contrast of images and displays, performed by either software or hardware, and designed to correct for the fact that the intensity displayed on a cathode-ray tube is not linearly related to the input voltage
Type of radioactivity in the most common form of which an unstable atomic nucleus dissipates energy by gamma emission, producing gamma rays. Gamma decay also includes two other processes, internal conversion and internal pair production. In internal conversion, excess energy in a nucleus is transferred to one of its own orbiting electrons and the electron is ejected from the atom. In internal pair production, excess energy is converted into an electron and a positron, which are emitted together. Typical half-lives (see half-life) for gamma emission range from about 10^-9 to 10^-14 second
Subgroup of the globulins. In humans and many other mammals, most antibodies are in the gamma globulin fraction of blood. A human gamma globulin preparation may be administered (by injection) to persons lacking immunity, either generally or to a particular disease, after exposure or before expected exposure
a club drug available in liquid or powder form is taken orally (frequently combined with alchol); used to incapacitate individuals for the commission of sexual assault and rape
Radiation composed of photons emitted during the process of nuclear transition or annihilation of the particles High-energy electromagnetic radiation with a very short wavelength and no mass, which is emitted from many types of nuclei Gamma radiation is just like ordinary light and X-rays, but has a much higher energy Gamma radiation is very penetrating and can only be effectively absorbed by dense materials such as iron, concrete or lead The thickness of shielding required can be anything between a few centimetres and a few metres, depending on the energy and intensity of the radiation
Gamma radiation is a type of high energy electromagnetic radiation which is emitted during the disintegration of certain radioactive isotopes such as 125I and 57Co, which are used as tracers in immunoassays Gamma emitting samples are measured in solid crystal scintillation counters These solid crystals, are usually thallium activated sodium iodide and are different sizes to accommodate lower and higher energy radioisotopes
High energy electomagnetic radiation that is emitted from an atom's nucleus has no mass or electrical charge has high penetrating power, and can pass though the human body
Gamma radiation is short wavelength electromagnetic radiation, of the same physical nature as light, X-rays, radio waves, etc However, gamma radiation is highly penetrating (more so than X-rays) and depending on its energy, may require a considerable thickness of lead or concrete to absorb it Since gamma radiation causes ionisation it constitutes a biological hazard
Highly penetrating, short wavelength radiation emitted from the nuclei of atoms It is stopped by an adequate thickness of lead, concrete or other materials
Gamma rays are high-energy, ionizing radiation that travel at the speed of light and have great penetrating power They can cause skin burns, severely injure internal organs and have long-term, physiological effects (FEMA-SS)
Similar to x-ray (photon radiation) but much more powerful It is not a laser Gamma radiation is invisible, cannot be felt and is able to penetrate deep through tissues The radioactive source is Cobalt-60
High-energy, short wavelength electromagnetic radiation emitted from the nucleus of an atom Gamma rays are very penetrating and are shielded by dense materials such as lead Gamma rays are similar to X rays
Electromagnetic radiation emitted by radioactive decay and having energies in a range from ten thousand (10) electron volts. a beam of light with a short wavelength, that can pass through solid objects radi'ation. Penetrating very short-wavelength electromagnetic radiation, similar to an X ray but of higher energy, that is emitted spontaneously by some radioactive substances (see gamma decay, radioactivity). Gamma radiation also originates in the decay of certain subatomic particles, and in particle-antiparticle annihilation (See also antimatter). Gamma rays can initiate nuclear fission, can be absorbed by ejection of an electron (see photoelectric effect), and can be scattered by free electrons (see Compton effect)
Study of astronomical objects and phenomena that emit gamma rays. Gamma-ray telescopes are designed to observe high-energy astrophysical systems, including stellar coronas, white dwarf stars, neutron stars, black holes, supernova remnants, clusters of galaxies, and diffuse gamma-ray background radiation found along the plane of the Milky Way Galaxy. Because Earth's atmosphere blocks most gamma rays, observations are generally conducted by high-altitude balloons or spacecraft. In the 1960s defense satellites designed to detect X rays and gamma rays from clandestine nuclear testing serendipitously discovered enigmatic gamma-ray bursts coming from deep space. In the 1970s Earth-orbiting observatories found a number of gamma-ray point sources, including an exceptionally strong one, dubbed Geminga, that was later identified as a pulsar, the nearest yet detected. The Compton Gamma Ray Observatory, launched in 1991, mapped thousands of celestial gamma-ray sources; it also showed that the mysterious bursts are distributed across the sky, implying that their sources are at the distant reaches of the universe rather than in the Milky Way
