NEW IN CONTINUUM 2021, the BCC+ Low Contrast filter spreads highlights into darker areas, lowers contrast and keeps bright areas bright.
Presets and the FX Editor
To select from a selection of factory installed and user-generated presets, open the FX Editor interface and pick one from the Presets window.
- Light Brightness: Sets the intensity of the light that is spread into darker areas.
- Light Spread: Sets how far light is spread from bright areas to darker areas.
- Shadow Brightness: Adjusts the brightness of the shadow areas.
A matte is used to create the light spread effect.Wherever there is white in the matte is where the contrast adjustment will occur.
Position: Pinpoints the color values to be used in the matte. For a luminance matte, a Position value of 100 would make a white matte of the highlights and a value of 0 would make a white matte of the shadows. In the flower image below, look at how the matte varies for different Position values in a red extraction. When the Position is at a value of 100, the red flowers are shown as white in the matte.
When the Position is moved to 50, the red flowers turn black.
Range: Increases or decreases the range of values in the matte. A low Range value indicates a narrow range of values. A high Range value indicates a large range of values included in the matte.
Blur: The matte is blurred by a quality blur.
