630 Corel PaintShop Pro X7 User Guide
is stored in a certain number of computer bits — from 1 bit to 48 bits.
In a 1-bit image, each pixel can display only one of two colors — black
or white. In images with greater bit depth, each pixel can display one
of an increasingly large number of colors. High-end digital camera
photos saved in the camera’s RAW format contain the most colors, but
they also require more hard drive space, and more system memory to
display and work on them.
In Corel PaintShop Pro, you can use the following color depths:
•2 colors
16 colors
256 colors
8-bit per channel RGB
8-bit per channel Grey
16-bit per channel RGB
16-bit per channel Grey
Before you change the color depth of your image, consider the
following:
Many effect and correction commands work on higher color
depth images only. After you finish working on an image, you can
decrease its color depth and save it in another format.
Computer monitors also have a color depth that is determined by
the monitor’s capabilities as well as the selected color setting. If
you display an image with a higher color depth than the monitor
can display, the image has some color distortion.
Some file formats limit the number of supported colors so that
images display correctly on a variety of monitor types. For
example, GIF images, a popular format for the Web, contain up to
256 colors (8-bit depth).
