ADJUSTING THE SETTINGS ON THE SCAN MANAGER PRO 41
For example, if you select Red from the menu and drag the
Brightness and Contrast sliders, you can see how the red
component of the histogram changes. Note, however, that the
Green and Blue components also change relative to those new
brightness and contrast settings.
3. Click the Auto button to have the scanner analyze the image and
set the appropriate brightness and contrast.
You can also adjust the brightness and contrast by sampling portions of
the image in the preview window. The three Sampler buttons
correspond to the Black, Mid tones, and White portions of an image.
To use the Sampler buttons:
1. Click one of the buttons.
The pointer automatically moves onto the image and becomes a
sampler pointer.
2. Place the pointer on the portion of the image for that sample and
click.
For example, if you selected the Black sampler button, place the
pointer on the blackest part of the image.
3. Repeat with each of the other Sampler buttons.
4. Click Adjust.
The image changes to show your new settings.
If the image is not what you want, click Reset to return the image
to its original brightness and contrast.
ADJUSTING GAMMA, SATURATION, AND COLOR HUE
If you’re using the Color Configuration to scan, you can adjust a group
of color settings. Gamma controls the brightness of the midtones of the
color, saturation is the strength or purity of a color, and hue is the color
your eyes see as reflected from the image. These color settings are
represented by a response curve.
