Advanced Scanning

black and white line art requires only
1 bit per pixel.
Scanning an original as a color
image requires three times the
storage as scanning it as a grayscale
image, and 24 times the storage
requirement of a black and white line
art image.
Size What are the dimensions of the
original? Scanning a 2" x 2" original
creates a smaller file than scanning
an 8" x 10" original.
Scaling Scaling (enlarging or reducing) an
image changes the file size
accordingly. For example, scanning
an image you scaled to 150% of its
original size requires 50% more
storage than if you had scanned it at
100% (no scaling).
Resolution Resolution is the amount of detail
that shows in an image, measured by
the number of dots per inch (dpi).
