The BCC+ Glow Edges filter isolates lines and edges in an image and then adds glow only to these areas resulting in a stylized look.
Before and After
Presets and the FX Editor
The FX Editor provides a convenient way to store and retrieve factory installed and/or user generated filter presets. To select a preset, open the FX Editor interface and pick one from the Presets panel. Click the apply button in the FX Editor to return to the host user interface.
To save a custom preset, click the “Create Custom Preset” icon in the top right corner of the parameter list, next to the filter name, set a name for the new custom preset in the dialog that appears and click done.
Blend: Determines the blend mode to be used to create the glow effect.
- Add: The glow is added to your image.
- Screen: The glow 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 glow.
Blur: Sets the softness of the glow.
Color: The Color parameter sets the color of the glow through the use of a standard color picker. The default color is white.
An edge matte is created to produce the edge glow effect.
Brightness: Determines the brightness of the edge matte.
Blur: Blurs the edge matte.
**Glow From Alpha:**The Glow From Alpha option generates the image glow from the alpha channel instead of or in addition to the color channels. The selection in the Glow From Alpha Mode determines how the alpha glow and the color channel glows are combined.
Glow Under Source: Use this function to control how the glows are composited with alpha source clips – a setting of zero composites the glow on top of the source and disregards the source alpha channel, while a setting of 100 composites the glow behind opaque regions in the source but allowing them to extend out into the transparent regions.
Mix with Original: Used to blend the filter effect back with the unfiltered input image.
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.
