BCC+ DeFog

Category: BCC Color & Tone

Effect Name: BCC+ DeFog

The BCC+ DeFog filter, part of the BCC Color & Tone category, restores clear day contrasts and colors of a scene taken in bad weather such as fog and mist. It is also successful in removing the effects of optical Fog and Diffusion filters.

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.

Defog Group

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

Vanishing Point

A vanishing point along the direction of increasing distance in the image is used to remove fog. By default, the vanishing point is set to the center of the screen. Essentially, the fog is removed in a radial pattern emanating from the vanishing point. So at the default center position, fog is removed in a circular pattern with a greater amount of fog being removed from the center while falling off at the edges. For instance, if your fog moves in the direction of top right to bottom left, set your vanishing point towards the top right corner and the fog removal will be more intense at the upper right and fall off at the bottom left. However, in most cases, the vanishing point can be left in the center of the screen and you will obtain acceptable results.

There is an on-screen control in the center of the image. By clicking and dragging the on-screen control, the position of the vanishing point can be adjusted along the X/Y axis.

• Defog: Sets the amount of fog to be removed from the scene.
• Min Depth: Controls how much fog is removed from the darker areas of the image.
• Max Depth: Controls how much fog is removed from the brighter areas of the image.

Color Correct Group

• Hue: Rotates the hue of the image.
• Saturation: Adjusts the saturation of the image*.*Positive values saturate, negative values desaturate.
• Brightness: Adjusts the brightness of the image. Positive values brighten, negative values darken.
• Contrast: Adjusts the contrast of the image. Positive values increase contrast, negative values decrease contrast.
• Gamma: Adjusts the gamma of the image. The gamma adjustment leaves the white and black points the same and only modifies the values in-between. Positive values lighten the midtones, negative values darken the midtones.
• Temperature: Sets the color of the image to be either warmer or cooler. Dragging the slider to the right makes the image cooler (bluer) and dragging the slider to the left makes the image warmer (redder).
• Cyan/Magenta: Adds either Cyan or Magenta to the image. Dragging the slider to the right makes the image more magenta and dragging the slider to the left makes the image more cyan.
• Red: Adds or subtracts red from the image.
• Green: Adds or subtracts green from the image.
• Blue: Adds or subtracts blue from the image.
