Color can be added to the Minimum Level by adjusting the Lighting Level Red/Green/Blue
and Master controls.
Lighting Level – Red/Green/Blue
This controls the red/green/blue components of the ‘minimum lighting’ as it is applied to the
foreground subjects. The control range is from 0% to 200%, with the default setting at 100%.
Lighting Level – Master
The master control adjusts all three ‘minimum lighting’ level R/G/B controls simultaneously
while maintaining their individual setting relationships.
Layer Color Controls
When the ‘lighting’ feature is enabled, the ‘layer white level, Black Level, Contrast, and
Saturation controls will make corresponding adjustments to the Lighting Input image.
For a detailed description of these controls, see Adjusting Brightness, Color, Contrast
and Saturation section of the manual.
Layer Input
Enabling this function allows the layer elements to be added to the composite scene.
Layer Input Realistic/Linear/Additive
This function selects between three modes of combining the layer input elements with the
foreground objects and the background scene in the composite image.
Realistic
Most accurate method of combining colored transparent and semi transparent layer elements,
as well as opaque layer elements, with the foreground objects and the background scene.
NOTE
When using a layer source graphic in realistic layer mode with semi transparent
objects, the image source background needs to be 100% white. The RGB elements in
the source layer should not be premultiplied by its matte. All feathering of transition
regions along edges of the matte should be within the boundaries of the layer
elements. For example, make sure feathered edges do not extend into the white
backing region of the source image.
Linear
Traditional method of combining opaque layer elements with the foreground objects and the
background scene in the composite image. This method will not produce accurate results with
transparent colored layer elements. This method should be selected if the layer elements are
not premultiplied.
Additive
Traditional method of combining opaque layer elements with the foreground objects and the
background scene in the composite image. This method will not produce accurate results
with transparent colored layer elements and should be selected if the layer elements are
premultiplied.
TIP
Clicking the ‘auto key’ button will not change the layer input mode.
