Each device capable of reproducing color has a unique gamut determined by age, frequency of use, and other elements such as inks and paper. See also device characterization, device dependent, gamut mapping, ICC profile. gamut mapping The process of identifying colors outside a device's gamut and then calculating the nearest color within its gamut. Gamut mapping is used when receiving color information from another color space. See also color space, gamut. grayscale An image whose only colors are shades of gray. Usually grayscale images have smaller file sizes because less information is required to display a gray pixel, in which the red, green, and blue pixel elements all emit an equal intensity.

ICC profile Created as a result of device characterization, the ICC profile contains the data about the device's exact gamut. See also device characterization, gamut, International Color Consortium (ICC). image An artifact that reproduces the likeness of some subject, usually a physical object or person, also known as a picture. See also image selection, photograph, picture, subject. image selection Refers to an image or group of images selected in the Browser or Full Screen view filmstrip.
