IMAGING PROGRAMS: PICTURE THE RESULTS
You can use imaging programs to capture a wide
variety of artwork, illustrations, and photographs
into image files. Scanned images fall into three
categories: line art, gray scale, and color.
Line art includes all drawings made up of black
and white only, with no gray tones. Both of the
illustrations on the left are examples of line art,
even though the artist has used lines that look like
shading in the second one.
Gray scale (also called monochrome or contin-
uous tone) refers to images such as black and
white photographs that contain various shades of
gray in addition to black and white. You can also
scan a color photograph as gray scale if you
want to print it in black and white.
For color reading, the scanner divides the various
colors in the image into three primary colors: red,
green, and blue. Epson's powerful 24-bit color
scanners devote 8 bits/pixel to each of the three
colors, so the scanner can represent over 16
million colors.
Use color scanning for color photographs or other
originals which will be printed or presented in color.
