Manually editing an image in SilverFast™ DCSE
After evaluating this image we know that the front of
the boat in the lower right is the darkest point, we also
know that this boat is pure black. Generally when edit-
ing, we would want this area to have only a few values
to retain some future editing flexibility. We also know
that the color values need to be equal in order to in-
sure that our digital prints do not have any color casts
in the shadows. Lets shoot for RGB values of 5-5-5.
The quickest way to edit an image is to begin with the
shadow point, and work methodically up the tonal scale
to the whitest point making decisions along the way
based on the cumulative results of each adjustment. If
you make a mistake, you may always undo the last step
by pressing Command-Z.
SilverFast incorporates many tools that may be used to
fine tune an image. Each tool offers automatic as well
as manual controls allowing you the freedom to experi-
ment with several editing approaches. This flexibility
is what makes SilverFast such a powerful image editing
tool.
Shadow adjustments
To automatically adjust the shadow point of your im-
age. Click once on the black triangle and then select
the darkest point in your image. The selected shadow
point will be adjusted to an RGB value of 5,5,5.
Highlight adjustments
To automatically adjust the highlight point of your
image. Click once on the white triangle and then select
the lightest point in your image. The selected shadow
point will be adjusted to an RGB value of 249,249,249.
Note: If you wish to adjust density only while retaining
the existing color cast of the image, hold the Shift key
while clicking on the Automatic adjustment button.
The tones will be adjusted, but
color balance will be maintained.

Mid tone Balance adjustment
Between the black and white triangles on the icon,
you will see an eyedropper tool. This tool allows you
to pick a neutral point in the image. Click once on the
eyedropper, then click any area of the image that you
wish to be neutral of color. This tool does not alter
density, but is extremely useful to improve the color
balance of your images.
Manual Level and Curve adjustments
Often times the application of automatic image adjust-
ments will over-enhance an image. Silverfast™ has the
ability to fine tune the image density via an interactive
levels dialog. Clicking on the Levels icon will reflect the
effect of the automatic highlight-shadow adjustments.
Clicking on the Curves icon will reflect the effect
of the automatic highlight-shadow adjustment. The
individual tools in SilverFast™ inter-operate to give you
multiple options for making image adjustments. Using
the automatic settings as a guide, you may alter Levels
and Curves values to improve image quality.
Levels and curves adjustments are essential to any
image editing session. Gaining an understanding of the
operation of these tools will allow you to quickly fine
tune images for high quality reproduction. The follow-
ing section will review the process of editing levels and
curves as well as the key features of SilverFast™ DCSE
