CCD |
|
CCD stands for Charge Coupled Device. It is a light sensitive solid-state device that is used in digital cameras, most desktop scanners (and some higher-end ones), colorimeters, video cameras, and other devices. Their dynamic range is improving but is still not up to that of the PhotoMultiplier Tubes used in drum scanners.

LCH |
|
LCH or more correctly CIEL*C*H is the same device-independant color space described by CIELab but using Lightness, Chroma, and Hue. L is lightness, the same as in Lab C is Chroma and represents how far out from the center of the color space (radially) the color lies. The farther out the more saturated the color. H is Hue and represents the angle of the color ?around? the color space.See CIELab for more information about the color space itself.

Absolute Colorimetry |
|
Measuring the color performance of a device relative to an "absolute" CIE white (e.g. D50) rather than to the device's natural white point. The natural white point of a printer is the color of the paper or substrate. The natural white point of a color scanner is the clear drum or clear slide holder.

Adjustment Profile |
|
A custom adjustment or set of edits that alter image appearance. Typically this profile is an 'abst' or Abstract profile that has Lab or XYZ as its input and output color spaces.
