Manually Adjusting Highlights and Shadows
The Auto Adjust feature automatically adjusts the highlights and shadows
of the selected image. However, if you want you can manually adjust
them. You can even have SilverFast Lite show you the brightest and
darkest points in the image so you know where to select them. See
Displaying the Brightest and Darkest Image Points
for details.
To manually adjust highlights and shadows, follow these steps:
1 Click the Highlight/Shadow Control button, then move the mouse
pointer onto your prescan image; the pointer changes to a white
triangle (for highlights).
2 To adjust the highlights, click the lightest area of the image. (See
Displaying the Brightest and Darkest Image Points
to find the lightest
area.) SilverFast Lite adjusts the image highlights by making your
selection white and correcting darker tones accordingly.
3 To adjust the shadows, click the Highlight/Shadow Control button,
then move the mouse pointer onto your prescan image and press and
hold down the Alt key (Windows) or option key (Macintosh). The
pointer changes to a black triangle (for shadows).
Click the darkest area of the image. (See Displaying the Brightest and
Darkest Image Points to find the darkest area.) SilverFast Lite makes
your selection black and adjusts all lighter tones accordingly.
If you need to reset the highlight and shadow adjustments to their default
settings, hold down the Alt key (Windows) or the command and option
keys (Macintosh) and click the Highlight/Shadow Control button to
reset them.
You can compare the
original highlight and
shadow values with
the new values by
viewing the
densitometer.
See Using the
Densitometer for
details.
To preserve color
casts as you adjust
the highlights and
shadows, press the
Shift key while you
make adjustments.
