Scanning Hints

B/W & Greyscale Scanning
If scanning B/W images, match the DPI to the resolution of
your printer, or scanner. For example, if you have a 300-dpi
scanner, then set the resolution to 300. If you have a 600-dpi
printer, set the scanning resolution to 600.
When not scanning using B/W, but rather Greyscale, we
find that a resolution of 150 works extremely well.
Sometimes increasing the brightness and contrast can help
improve and lighten the greyscale image quality.
Colour Scanning
When scanning in colour, remember that 24 to 30 bits of
information take up a lot of disk space. If you are going to scan a
colour image and then print it out, scan at 200 dpi. If you are
going to scan a colour image just to experiment, scan between 75
and 100 dpi to conserve hard disk space.
