2.3.16 Selective Color Correction in SilverFast SE (Plus) 8

If the overall color balance of a picture should not be changed, but rather just a single color adjusted, Selective Color Correction (SCC) is used. Use of Selective Color Correction is especially practical when one color is contaminated with traces of another. The tool provides access to the six base colors red, green, blue, cyan, magenta, and yellow. For each of these colors there is a menu with preconfigured adjustments and a slider that can be used to change the color value. The color value slider offsets the selected color to one of its neighboring colors on the color circle, that is, for example, red to yellow or magenta, or cyan to green or blue.
Our example image can't simply be neutralized with the pipette because there are no suitable black, white, and neutral points. The approximate neutralization using the image automatic "Shadow cast" and subsequent correction by hand in the histogram highlight our starting image (top left). To allow the flower to stand out more clearly, it and the background must be differentiated from one another in color, that is, the flower should be more clearly yellow and the background more clearly green. The shadowed areas in the background contain a blue and cyan cast. We use the drop-down menu in the line for blue to select "weaker", to reduce the blue in general. Then we select cyan by clicking on one of the squares for processing. We push the H slider upwards to move the cyan portions to the green end, since green is the dominating color of the background and we want to reinforce that even more. With the H slider for green, we offset the yellow portion of the background a little towards the cyan, allowing the yellow of the flower to contrast better with the background. Finally, we process the flower. It contains a beautiful yellow that needs no further adjustment. But the yellow is contaminated with red, which can be pushed slightly towards yellow by moving the red H slider. In the result (the image on the top right), the green, out-of-focus background and the yellow flower in focus stand in a clear contrast to one another. This emphasizes the flower as the central element of the picture.
