Kelvin |
|
|
An absolute temperature scale used in scientific circles. The "color temperature" of a light source, monitor or image area, defined in "degrees Kelvin" (°K), is the temperature a perfectly black radiating object would be if it glowed that shade of white. Average daylight is standardized at 6500°K (Europe) and 5000°K (North America). Higher temperatures are bluer, lower temperatures are redder.

Lightness |
|
|
The brightness of an area expressed relative to the whitest area in the viewer's field of vision or the brightest white the device is capable of seeing or producing.

Linearization |
|
|
The process of measuring and correcting for a device's inability to see or reproduce a straight line of tones from black to white. Most commonly used to ensure an image setter reproduces the same halftone dot values predicted by the imaging software. Linearization

Link |
|
|
Combining an input profile with an output profile produces a mathematical look-up-table (LUT) that translates colors from an input device into the best available matching colors on the output device. Changes or edits can be combined in the link to alter or improve the image.

|
Metamerism |
|
|
The phenomenon by which two materials that match under one circumstance appear different to different viewers or under different lighting. Metameric mismatch occurs when tristimulus values are the same but spectral characteristics are not.
