Glossary

Bits are small units of computer memory. The color depth of your image is constrained by the number of bits available to store

color information. For example, it is possible to store 256 different color values per color channel in 8-bit RGB images. Similarly,

it is possible to store 65,536 different color values per color channel in 18-bit images.

blackpoint

An image’s darkest area. You can control the intensity of the black in an image by adjusting its blackpoint.

blend modes

Filters that change the effect of a tool or the appearance of a selected object.

brightness

Light intensity of an image. You can make an image appear brighter or darker by adjusting its brightness.

cache

High-speed storage mechanism. The ACD Systems Database is a cache.

caption

Text associated with a file, or a comment or description added to a printed image.

cataloging

Adding file information to the ACDSee 14 database.

category

Assign categories to photos to help sort and manage them more easily.

chromatic aberration

A lens artifact that can result in fringes in high contrast areas of some photos.

CMYK

Color model that uses cyan, magenta, yellow, and black (key) as its primary colors.

color cast

Changes the hue of an image while keeping the saturation and brightness intact. For example, many digital cameras produce

pictures with a slightly blue color cast. ACDSee 14 includes a tool that removes an unwanted color cast.

color channel value

Contains all pixel information for a single color. A grayscale image has one channel, while an RGB image has three channels. You

can adjust RGB values when editing a color.

color gamut

Range of colors that a device such as a printer or monitor can produce or display.

color management

Process of adjusting your computer settings so that the color output from your printer matches the colors you see on your

monitor.

color space

There are two types of color spaces: device-independent or device-dependent. A device-independent color space, such as RGB,

describes all possible colors. A device-dependent color space describes the subset of colors (from the device-independent color

space) that a particular device can reproduce. Device-dependent color spaces are used to map colors between devices (for

example, from a monitor to a printer) to ensure that colors are reproduced accurately.
