The controls on the second tab sheet at the top can be used to color correct the shadows in the Shadows/Highlights modes, colorize all spot lights in the Virtual Studio modes and modify the color of certain color areas in the Color modes. The controls on the fourth tab sheet are identical and let you adjust the color of the highlights in the Shadows/Highlights modes and colorize background areas in the Virtual Studio modes.


The Method combo box offers four methods that determine how the shadows or highlights will be color corrected with the values from the Red, Green and Blue sliders.



The Adjust slider lets you weaken or strengthen the effect of the Red, Green and Blue sliders. Values below zero produce a weaker color correction and values above zero increase the color correction intensity. A value of -100 neutralizes the Red, Green and Blue values, so that no color correction is applied.


Red, Green and Blue

You can use these sliders to set the color with which the shadows or highlights are corrected. Negative values select the antagonistic color, which is Cyan for Red, Magenta for Green and Yellow for Blue.

The selected color is displayed in the box at the left of the three sliders. You can also double click this color box to choose a color from a color dialog. The Red, Green and Blue sliders will than be adjusted accordingly.


Using the Eyedropper Tool

Instead of using the sliders or color dialog to set a color you can also use the eyedropper tool that is activated with the appropriate icon above the preview. With the eyedropper tool you can click on the preview to choose a color.

In the Color modes the eyedropper tool simply lets you select a color from preview that will be added to the color box on the tab sheet.. In the Shadows/Highlights and Virtual Studio modes the opposite of the selected color will be added to the color box. As a result the shadows, highlight, spot or background areas are color correct semi-automatically. So best click on an image area in the preview that you want to turn to white or gray.

The clicked color will be assigned to the color box that is activated. By the default the color box on the second tab sheet is activated. If you want to assign a color to the color box of the fourth tab sheet, please switch to the tab sheet and click on the color box. Now you can click on the preview with the eyedropper tool. To switch back to the color box on the second tab sheet click on it.



The combo box at the left of the Saturation slider lets you choose the saturation method. "Saturation" is the standard way of adjusting saturation, but it may add artifacts at higher Saturation slider values. "Median Sat.", "Lumi Sat." and "Average Sat." usually doesn't do that. The six last options represent color filters that protect the saturation of the color they are named after. For example, the "Yellow Sat." option keeps yellow objects from being saturated too much while saturating other colors normally. It also prevents too much color noise appearing in those yellow objects.

Positive values of the Saturation slider increase saturation in the shadows or highlights whereas negative values reduce saturation. For normal correction saturation increases or decreases between -20 and 20 are sufficient. Some shadow correction may create a serious saturation or B/W increase. If you are not able to compensate for that effect with other sliders, you should consider using higher values for the Saturation slider.

Dragging the Saturation slider to the outer left position turns the image to B/W. Together with the Sat. Method combo box this is another way to create B/W variations of your image.
