NEW IN CONTINUUM 2021, the BCC+ Streaks filter creates horizontal or vertical streaks around highlights in the image.

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.

Filter Parameters

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

• Add: The light is added to your image.
• Screen: The light 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 streaks.

Streaks

Horizontal Streaks: Creates horizontal streaks.

Vertical Streaks: Creates vertical streaks.

Color

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

Matte

A matte is used to create the streak 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 simple, built-in masking of the effect result.  The PixelChooser is generally used to select a portion of the image and restrict an effect to just the selected area while maintaining the original image content in unselected regions.  The selection can be based on geometric shapes or on the image’s luma/color properties.
