Filter Parameters

Fog

Blend: Determines the blend mode to be used to create the fog effect.

• Add: The fog is added to your image.
• Screen: The fog is combined with the image using a Screen blend mode. This looks kind of like the Add blend mode, but highlights are retained.

Brightness: Sets the intensity of the fog.

Blur: Sets the softness of the fog.

Color: The Color parameter sets the color of the fog through the use of a standard color picker. The default color is white.

Matte

A matte is used to create the fog effect

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.

PixelChooser: The BCC PixelChooser provides a way for the user to select which pixels in the filtered source are actually going to be affected by the filter, via the generation of image based mattes, gradient mattes and vector shape masks. Mocha planar tracking and vector shape masking options are included in the PixelChooser, which allows for the generation of motion-tracked mask shapes as a hold-back mask.
