Selective color correction
Often times, you will want to alter the relationships
between colors, or the balance of specific colors in
an image. Selective Color Correction is the tool in
Silverfast™ to perform these tasks. The easy to use
interface simply offers you pull down menu items for
each color family. Selecting the various options will al-
low you to quickly make the sky a darker blue, or a skin
tone warmer while leaving other colors untouched.
Note:
SilverFast™ DCSE is a version of a more fully featured
application called SilverFast™ DC PRO. This program
offers even more control of selective color including
an interactive color wheel interface, and the ability
to alter the individual hue saturation and lightness for
each color. Visit http://www.silvefast.com for more
information.
Picture Settings
Silverfast™ DCSE incorporates multiple methods to
accomplish the same tasks. For example, we have
identified several ways to perform color adjustments
to an image in this section. As the development of
SilverFast™ began in the world of film scanning, new
features have been added to assist editing direct digital
captures. While these tasks could be accomplished us-
ing the more traditional tools such as levels, endpoints,
and curves, in many ways the digital image controls are
faster and less subjective.
Exposure
When opening raw file format images, the exposure
tool has full access to the entire 12 bit capture bit
depth. It is possible to improve images that were inad-
vertently under-or over-exposed.
Light Source
The most useful feature in the Picture Settings dialog is
the Light Source tool. In the drop down menu, you will
see multiple light source options and a custom option.
If you choose Custom, and then click on the eyedropper
tool, your cursor will change to a gray triangle when it
is positioned over your image. Select an area in your
image that is neutral in tone, and the software will
force the point to become neutral. The Color Tempera-
ture readout will reflect the actual color temperature.
Clicking on a known neutral area in your scene will
create a custom color temperature (white balance).
Color Temperature
If your color as captured is not satisfactory, and your
image does not include a neutral area to assist in
creating a custom adjustment, you may slide the color
temperature slider, or enter the approximate color
temperature of the lights your subject was illuminated
with during capture.
For example:
If you scene was illuminated using tungsten lighting try
setting the color temperature to 3200k.
Color Tint
Used primarily as a creative control, the color tint
slider simply biases the Hue of the entire file. This is
the equivalent of a color correction gel in traditional
photography. However, there is no numeric equivalent
to traditional photographic filtration. When using this
feature, we suggest testing several images.
