BCC+ DeFringe

Category: BCC Lens

Effect Name: BCC+ DeFringe

The BCC+ DeFringe filter, part of the BCC Lens category, isolates and removes different types of color fringing. Purple or blue fringing around overexposed areas is commonly caused by sensor overload in video and digital still cameras.

Working with the Filter

FX Editor and Presets

• Use the FX Editor to load or save presets for reuse.
• To load a preset: Open the FX Editor, select a preset from the Presets panel, and click Apply to return to the host application.
• To save a custom preset: While in the FX Editor, click the Create Custom Preset icon in the parameter list, enter a preset name, and click Done. Additionally, a custom preset can be saved from the main menu bar by selecting File->Save Preset.
• To import custom presets from another drive: While in the FX Editor, select File->Import Preset from the main menu bar.

Effect Controls

Mocha Mask and Track

Continuum effects include integrated masking and matte tools that allow you to restrict the effect to specific regions of the image.

• Mocha masks: used to create custom spline masks. Mocha also includes Matte Assist ML and Matte Refine ML, which use machine learning to generate and track masks.
• Pixel Chooser: used to generate geometric shapes, gradients, or mattes based on channel, luma, or color-based selections. Additionally, an AI depth map generator, and an AI-powered face detection model allow for precise control of masks and mattes.

For more information, see Mocha and Pixel Chooser.

Compare Mode

The Compare Mode is used to view the filtered result alongside the original source layer. Several split-screen and side-by-side display options are available.

For more information, see Compare Mode.

• View: Allows you to set the viewer to display various channels.
  • Output: Shows the final processed look of the BCC+ Defringe filter on the image.
  • Red: Shows the red color matte.
  • Green: Shows the green color matte.
  • Blue: Shows the blue color matte.
  • Cyan: Shows the cyan color matte.
  • Magenta: Shows the magenta color matte.
  • Yellow: Shows the yellow color matte.

  Each color group generates a matte to isolate fringing in a specific hue range. White areas in the matte indicate pixels that will be affected (defringed).

  Color Groups

  Each color group targets their respective hue range, allowing for adjustments to the saturation, hue, and range.

  • Red/Green/Blue/Cyan/Magenta/Yellow:Adjusts saturation of color values in the isolated fringe areas. Positive values increase saturation; negative values decrease saturation.
  • Position: Shifts the hue targeted by the generated color matte. Use this if the fringing hue does not match the default “red” target.
  • Range:Expands or narrows the hue range considered “red fringing.” Lower values target a tighter hue range; higher values target a broader range.
  • GPU Rendering:Specifies how the effect is rendered.
    • Default: Uses product-wide default of 16 bit half-float GPU rendering.
    • 16 Bit Float: Manually force 16 bit half-float GPU rendering.
    • 32 Bit Float: Manually force 32 bit full-float GPU rendering.
    • Disabled: Forces CPU rendering.
