Adjusting Brightness, Color, Contrast and Saturation

As you build your composite, you will likely want to make adjustments to the luminance,
color, contrast, and saturation levels for your sources which can help improve your composite.
For example, if the foreground, background and layer elements seem to differ in levels
compared to accompanying composited layers, you can perform an independent color
adjustment using the master controls for each source. All the same luminance, color balance,
contrast, and saturation settings are available for each source.

White Level Master

If a source seems too bright or too dark for the adjoining scene in the composite, adjust the
white level control to alter the brightness of the source rather than adjusting the original input
source level. Altering the level at the input source, for example the camera exposure, can
adversely affect the generation of the matte signal.
The default setting of the white level control is neutral at 100%. The range of the control is from
0% to 200%. The main unit will clip the output so the signal cannot exceed standard limits.
When adjusting the white level master, the relative difference between the white level red,
green, and blue components will be maintained.

Black Level Master

The master black control adjusts the level of black in the source image without altering the
white level. Adjusting the black level can often produce a more convincing composite image,
if the black levels in the background scene differ from those in the foreground.
When adjusting the black level master, the relative difference between the black level red, green,
and blue components will be maintained. Ultimatte 12 will clip black levels at zero so they do not
exceed standard broadcast limits.

Contrast Master

The contrast master control adjusts the overall contrast level of the source in the composite
without affecting the quality of the composite. For example, if the lighting contrast in the
foreground scene does not match that of the background scene, adjusting this control may
produce a more convincing composite image.
The contrast setting does not affect the strength of black and white levels, but only changes
the contrast of the gamma, or mid level gain, in the source image.
When adjusting the contrast master, the relative difference between the contrast red, green,
and blue components will be maintained.

Saturation Master

The saturation master control adjusts the saturation level of the selected source colors without
affecting the generation of the matte signal. For example, if the saturation of the colors in the
background scene does not appear to match the saturation of the foreground colors, adjusting
this control may produce a more convincing composite.
The saturation master control can completely remove all color from the source image and
produce a monochrome, or black and white, foreground composited with a color
background image.
When adjusting the saturation master, the relative difference between the saturation red,
green, and blue components will be maintained.
