International Color Consortium (ICC) An organization established to create the color management standard known as the ICC profile. ICC profiles are universally accepted by hardware and software vendors because they're based on an open standard. See also ICC profile. IPTC Short for International Press Telecommunications Council. IPTC metadata is used by photographers and media organizations to embed keywords (words describing the characteristics of the image, including the photographer's name) in the image files themselves. Large publishers typically use image management systems to quickly identify images based on the IPTC information embedded in the image. See also EXIF, metadata. iris See pupil. ISO speed The relative sensitivity of film provided as a benchmark by the International Standards Organization (ISO). In digital cameras, the minimum ISO rating is defined by the sensitivity of the digital image sensor. When the ISO setting on the camera is increased, allowing the photographer to shoot in low-light situations, the camera amplifies the voltage received from the light-sensitive elements on the digital image sensor prior to converting the voltage signals to digital values. See also digital image sensor, digital noise. JPEG Short for Joint Photographic Experts Group, JPEG is a popular image file format that lets you create highly compressed graphics files. The amount of compression used can be varied. Less compression results in a higher-quality image. JPEG files usually have the ".jpg" extension. See also format. kelvin (K) A unit of measurement used to describe color values of light sources, based on a temperature scale that begins at absolute zero. See also color temperature, White Balance adjustment. keywords Descriptive words about the subject in the image that are added to image versions and saved as metadata. See also control bar, Keywords HUD, metadata. Keywords HUD A floating window containing a library of keywords that can be applied to an image selection. See also keywords, metadata. lab plot A visual three-dimensional representation of the CIE Lab color space. See also color space, ColorSync. 656 Glossary
