Adjusting Color Controls

Check the color conformance box on the Ultimatte tab, and set these controls on the Color tab. A good keying result requires matched blacks, whites, and gammas between the foreground and background elements. With color conformance you can select blacks, whites, and gammas and can automatically match the foreground to the background (or vice versa).

• darks - You can use this control to influence the darkest parts of the image. This is a global control that affects the entire image, but the greatest effect is seen in the darkest areas.

• midtones - You can use this control to influence the mid-range parts of the image. This is a global control that affects the entire image, but the greatest effect is seen in the mid-range areas.

• brights - You can use this control to influence the brightest parts of the image. This is a global control that affects the entire image, but you can see the greatest effect in the brightest areas.

• hue - This control changes the color contents of the image without changing its brightness or color intensity (purity) values. At default setting (0), the image hue is not altered. The range of the control extends from -300 to +300.

• saturation - This control changes the color intensity or purity values of the image without altering its color contents or brightness values. At default setting (0), the image saturation is not altered. At minimum setting (-200), the color intensity is reduced to zero and the image is monochrome, or shades of gray.

• brightness - This control changes the overall intensity of the image. At the default setting, the image brightness is not altered.
