Adding file information to the ACDSee database.

Assign categories to photos to help sort and manage them more easily.
Clipboard
Microsoft Windows tool you can use to copy data from one source to another. You can use the
standard Copy and Cut tools to move items to the Clipboard, and the standard Paste tool to
import or apply a Clipboard item.
CMYK
Color model that uses cyan, magenta, yellow, and black (key) as its primary colors.
codec
Abbreviation for technology that compresses and decompresses data. A codec compresses files
for storage or for transport over a network such as the Internet. You can use the same codec
to expand files to their original size so that they can be played or viewed on a computer.
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 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.
command line
Usually refers to the MS-DOS prompt, at which a user can enter commands in a specific syntax
to start an application with certain options enabled or disabled.
compression
Process that converts data to a storage format requiring less space than the original data.
