BCC+ Kelvin

Category: BCC Color & Tone

Effect Name: BCC+ Kelvin

The BCC+ Kelvin filter, part of the BCC Color & Tone category, allows for the adjustment of standardized color temperature. Degrees Kelvin is the standard unit of measure for color temperature which is a way to characterize the spectral properties of a light source. Low color temperature implies warmer (redder) light, while high color temperature implies a colder (bluer) light.

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 outputs for the filter.
  • Output: Shows the default look of the BCC+ Kelvin filter on the image.
  • Grad: Shows the gradient. Useful when determining the look of the gradient used in the output.

  Color Group

  The Color Temperature of the image is determined by the difference of the Destination and Source Kelvin parameters. For instance, if your Source Kelvin is 3200 degrees Kelvin and you adjust the Destination Kelvin to 6500 degrees, your image would turn blue. This is the same as using tungsten indoor film meant to be used with lighting balanced for 3200 degrees Kelvin outside in daylight which is 6500 degrees Kelvin.

  • Destination Kelvin: Sets the destination color temperature of the image in degrees Kelvin.
  • Source Kelvin: Sets the source color temperature of the image in degrees Kelvin.
  • Opacity: Sets the opacity of the color temperature adjustment.
  • Preserve Highlights: Preserves the white areas of the image.
  • Exposure Compensation: Exposure Compensation adds back the brightness loss as a result of the color temperature application.

  Grad Group

  BCC+ Kelvin can optionally use a gradient that limits where the filter is applied. Grad is the transition area between the colored portion and the original image. Its direction, corners and size can be adjusted.

  • Enable: Turns the grad on and off.
  • ND Brightness: Darkens the colored portion of the grad.
  • Type: Controls the direction of the grad.
    • Top-to-bottom: The direction of the grad is from top to bottom.
    • Bottom-to-top: The direction of the grad is from bottom to top.
    • Left-to-right: The direction of the grad is from left to right.
    • Right-to-left: The direction of the grad is from right to left.
    • Horizontal Strip: Horizontal strip grad.
    • Vertical Strip: Vertical strip grad.
  • Size: The size of the grad.
  • Angle: The angle of the grad.
• Corner Pin:The grad can also be corner pinned by adjusting the Corner Pin sliders as well as dragging the four points on the corners of the screen.

• Upper-Left: Controls the X and Y position of the Upper Left Point.
• Upper-Right: Controls the X and Y position of the Upper Right Point.
• Lower-Right: Controls the X and Y position of the Lower Right Point.
• Lower-Left: Controls the X and Y position of the Lower Left Point.
