entire original image. From this low-resolution
scan you get a clearer idea of the image area
you want to include in your final scan.

11
(6) Set the Resolution
The Resolution, which is measured in dots
per inch (dpi), determines the effect of the
image as it is displayed or printed. Images
scanned at a high resolution capture more
information. However, high-resolution
images require more memory.
SeeScan Tips, Appendix A, (Pg. 26)
(3)Selectthe Scan Size

ScanSettings
TheMain Tab
The Main tab allows you to control the scanning
parameters, such as scan mode, scan source, resolution,
etc. These parameters determine how the original image
or document will be scanned.
ScanMode
TheScanMode determines how the scanner reads
the original image or document. When choosing
a scan mode, it is recommended to consider what
purpose the resulting scanned image will be used
for.
•LineArt

Resolution
The Resolution, which is measured in dots per inch (dpi),
determines the appearance of the image as it is displayed
or printed. Images scanned at a higher resolution capture
more information and therefore require more disk space
for storage. You can select from a wide range of preset
resolutions.
75 dpi 400 dpi
Descreen A tool for reducing moiré patterns in
scanned images of originals that were
created by a halftone process. Moiré
patterns appear as unsightly interference
patterns.

coarse dot patterns commonly found in newspaper
photos.

18
•Magazine
Choose Magazine when scanning images whose
quality is similar to images found in glossy or wax-
coated magazines.
•ArtPrint
Choose Art Print when scanning images from very
high quality art prints that show only very fine dots.
ColorMatch
This is an effective tool for ensuring that the colors
captured by the scanner more accurately reflect the actual
colors of the original image. Without color matching the
scanner captures a wider range of colors but these colors
may not accurately match the true colors of the original
image, making the scan appear different from the original.
Color Balance
This tool balances the lightest and darkest areas of an
image so that they are equally distributed.
Without Color Balance With Color Balance
OutputScaling Output scaling allows
you to enlarge/shrink
the size of the final
output image. Adjust the scaling by using the slide bar
or typing the desired setting in the Output Scaling box.
For example, setting the Output Scaling to 200% will
double the amount of pixels contained in the image.
Widthand Height
The Width and Height values show the dimensions of the
image area inside the Crop Frame. You can change the
measurement unit to centimeters or inches.
Image Size
Image Size displays the amount of disk space needed to
display or save the image outlined by the Crop Frame in
the Preview window. The Image Size information is
automatically updated anytime you change any of the
scan settings or resize the Crop Frame.

19
The Enhance Tab
The Enhance tab contains preprocessing controls that
can be applied to the image before making the final scan.
To access the Enhance tab, click Enhance.
The Enhance tab contains two picture thumbnails
(Original and Sample) of the preview image, several
control settings, and a histogram of the image.
Alterations made to the enhanc settings appear in the
sample thumbnail.
Thumbnails
The image that appears in the thumbnails will
automatically be replaced with the Preview image.
If you wish to see the effects of your changes in the
Preview Window, click on the Preview button.
ChannelSelector
Channel refers to the red, green, and blue
colors that make up a color image. You can
choose to change the channels individually
or choose Master to change all channels
equally and simultaneously. An image in Gray
Mode has one channel.
Histogram
The Histogram graph shows the distribution of brightness
levelsinan image. Using the control settings (Brightness,
Contrast, Gamma) you can selectively adjust the
brightness levels in the shadows, midtones and the
highlights of the image.
A diagonal line extending from
the lower left corner to the upper
right corner indicates there is a
balance between brightness and
shadows.

20
Using the Channel Selector allows the histogram to reflect
the distribution of brightness in an entire image or in
individual colors (Red, Green, and Blue).
HistogramButton
The Histogram Button allows you to view the
histogram as either a line graph or a bar graph.
As a bar graph, the horizontal axis represents
the brightness levels from darkest (left) to
brightest (right). The vertical axis represents
the amount of pixels with that brightness
level value. To adjust the display of the
histogram, click on the Histogram button
and then click on the + or - button.
BrightnessControl
Using 255 steps, this tool allows you to adjust
the overall amount of light in the image. A
value of -127 will make the image appear very
dark, whereas, a value of +127 will make the
image appear very bright.
Brightness -50 Brightness 0 Brightness 50
ContrastControl
Using 255 steps, this tool controls the disparity
in tone between the dark and light areas of an
image. Positive values create greater differences
between dark and light areas of the image,
whereas,negativevaluescreate greater similarities
between the dark and light areas of the image.
Contrast -50 Contrast 0 Contrast 50
GammaControl
The Gamma control is used for adjusting the
brightness level in the highlights, mid-tones, and
shadows of the image. Values of 0.1 to 2.0
primarily affect the shadow areas of the image.
Values of 2.1 to 6.0 primarily affect the midtone
areas, and values of 6.1 to 7.9 primarily affect the
highlight areas.
For Example:A gamma value of 1.9 will make the shadows
of an image appear brighter, whereas, a value of 0.2 would
darken these shadow areas (taking away brightness). The
histogram graph will display these gamma value effects
in the bottom right portion of the histogram graph
