Before adjusting color tones on the tone map, it is a
good idea to prescan the image. When this is done and
the image appears in the Prescan Area, any changes
made to the tone map will immediately appear on the
prescanned image. This enables you to see the effects
of the changes you make. When you are satisfied with
the results and finally click on the Scan button to scan
the image, the scanned image will contain the color
properties you have defined.
There are two ways to adjust tones on the tone map:
Clicking with the left mouse button on the graph as
mentioned above, remaps the color values to the
numbers shown in the In and Out boxes. All other
color tones will also be remapped to create a smooth
curve in order to keep the color of the image smooth.
The second way to alter the tone map (and possibly
the most useful) is to click on the diagonal line on the
graph and while keeping the mouse button pressed,
move the mouse. Let the cursor hover over a single
point on the graph while keeping the button pressed to
give your computer time to recalculate the changes,
and the results will show up on the prescanned image
in the Prescan Area. All other color tones will also be
remapped to create a smooth curve in order to keep the
color of the image smooth. Release the mouse button
