Adjusting Foreground Ambiance Controls
To make a composite more convincing, it is important that the foreground subject fits seamlessly
into its new background environment. The ‘ambiance’ feature in Ultimatte 12 analyzes the colors
of the background and foreground layers, and automatically adds subtle color influences from
the background into the foreground layer. This feature is enabled by default.
The ambiance controls also allow you to set the amount of influence that the background has
on the foreground layer, and finesse the color balance.

button is ‘enabled’.
Ambiance 1 Settings
The ambiance controls will add very subtle amounts of color from the background, simulating
reflected ambient light from the background source.
Ambiance Level Red, Green, Blue
Adjust these settings to increase or decrease effects of the red, green and blue
components of the background ambiance that will influence the foreground
color levels.
Ambiance Level Master
This setting adjusts the overall level of the ambiance that will influence the foreground
color levels. When adjusting this control, the relative difference between the ambiance
red, green, and blue components will be maintained.
Ambiance Strength
This setting adjusts the strength of the ambiance that will influence the main area of the
foreground subject, compared to the transition areas from the foreground subject to the
background scene. At its maximum setting, the ambiance will have full influence on the
main area as well as the transition region, while at the minimum setting, the ambiance
will have no influence in the main area while having a stronger influence in the
transition regions.
Direct Light Mix
This setting controls the proportion by which the foreground subject will be influenced
by the ambiance colors and user adjustable direct lighting. At the maximum setting,
the foreground subject is influenced entirely by the direct light controls, and at its
minimum setting, the foreground subject is influenced entirely by the ambiance colors.
Vertical Blur
This setting determines the number of averaged lines in the background used in
ambiance calculations. Depending on the background scene, reducing this control
could introduce streaking on the foreground layer.
Ambiance 2 Settings
The direct light controls will make more aggressive changes to the foreground image,
simulating light that is directly from a position in the front of the foreground subject.
Direct Light Red, Green, Blue
Adjust these settings to increase or decrease the impact of red, green and blue
components of the direct light that will influence the foreground color levels.
