SCANNER CONTROL TABS
Excellent color details can be obtained using this scan mode, but be aware
that True Color images require considerable disk space to save them. For
instance, an A4-size (8.5" x 11") 300-dpi True Color image may require 24
megabytes of storage space (uncompressed).
Additionally, a high color or true color graphics card is required to adequately
display the color information.
256 Colors
Images scanned in 256 Colors mode are scanned in a maximum of 256
colors. The quality is not as high as True Color, RGB, but it is acceptable for
most applications. File sizes are considerably smaller than those of True
Color, RGB. An A4-size 300-dpi 256 Color image may require 8 megabytes
of storage space (uncompressed). Photographs may be successfully
scanned in 256 colors.
Gray 256 Scales
Images scanned in Gray 256 Scales mode are scanned in 256 shades of
gray. If high quality copies of photographs or other continuous tone originals
are desired, Gray 256 Shades mode is the best choice.
Gray 256 Scales provides accurate representation of black and white, and
intermediate gray shades between black and white, for each individual pixel.
