Glow Filters

Glow filters combine blur with brightness and color effects. The results are automatically recomposited over the original image in many different ways. Glows can be used to simulate film effects, as a method to make your footage more abstract, or used more subtly, as accents to make individual elements in a composition stand out.

Aura

This is a highly stylized filter that adds light or dark halos around well-defined areas of an image. The resulting glow appears solarized, and the underlying image creates outlines that show through the glow effect.

Parameters in the Inspector
  • Inner Radius: Sets the amount the aura extends inward from its point of origin.
  • Outer Radius: Sets the amount the aura extends outward from its point of origin.
  • Brightness: Sets the brightness of the aura.
  • Crop: Sets whether or not the aura is cropped at the original boundaries of the object.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Inner Radius, Outer Radius, and Brightness.

Bloom

This filter simulates the effect of extremely overexposed highlights on film. Highlights above a certain threshold are blurred, brightened, and recomposited with the original. All unaffected regions of the image interact with the glow effect, but otherwise retain their detail.

Parameters in the Inspector
  • Amount: Sets the amount of the bloom.
  • Brightness: Sets the brightness of the bloom.
  • Threshold: Sets the luminance threshold at which the bloom starts.
  • Horizontal: Sets the amount of horizontal bloom.
  • Vertical: Sets the distance of vertical bloom.
  • Crop: Sets whether or not the bloom is cropped at the original boundaries of the object.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Amount, Brightness, and Threshold.

Dazzle

This filter adds glowing star-shaped accents to the highlights in an image. This filter can be customized to create anything from subtle highlights to outrageous, colorful flashes of color.

Figure. Canvas showing effect of the Dazzle filter.
Parameters in the Inspector
  • Amount: Sets the radius of the spikes from the glow of Dazzle.
  • Angle: Sets the angle of rotation of the spikes from Dazzle.
  • Brightness: Sets the amount of brightness of the glow of Dazzle.
  • Threshold: Sets the luminance threshold of the glow.
  • Spike Count: Sets the number of spikes coming off of the glows.
  • Crop: Sets whether or not the glowed object is cropped at its original borders.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Amount, Angle, Brightness, Threshold, and Spike Count.

Gloom

This filter creates a muted, dark glow. The image is darkened, and areas of fine detail are evened out into larger regions of color. It’s spooky.

Parameters in the Inspector
  • Radius: Sets the radius of the gloom.
  • Amount: Sets the amount of gloom. Values range from 0 (no gloom) to 2 (maximum gloominess).
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Radius and Amount.

Glow

The most basic glow filter in this category, which can be customized for a wide variety of effects.

Parameters in the Inspector
  • Radius: Sets the radius of the glow.
  • Opacity: Sets the opacity of the glow.
  • Threshold: Sets the luminance threshold at which the glow begins.
  • Softness: Sets the amount of softness applied to the glow.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Radius, Opacity, Threshold, and Softness.

Light Rays

A glow filter that uses the zoom blur to distribute the resulting glow, instead of a gaussian blur. The effect is that of light rays shining through an object from a specified point.

This filter causes rasterization in 3D groups.

Parameters in the Inspector
  • Amount: Sets the amount of the light ray effect. Larger values extend the length of the rays.
  • Center: Sets the position of the center point of the light source.
  • Glow: Sets the brightness multiplier of the light rays.
  • Expansion: Sets the distance the light rays extend outside the boundary of the source object.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Amount and Glow.

Outer Glow

Adds a glow to the alpha channel of an object. The result is a glow around the outside of an object, while the object’s actual image is unaffected.

Figure. Canvas showing effect of the Outer Glow filter.
Parameters in the Inspector
  • Radius: Sets the size of the glow.
  • Brightness: Sets the brightness of the glow.
  • Inner Color: Picks the inner color of the glow. Use the disclosure triangle to display Red, Green, and Blue sliders for more precise color selection.
  • Outer Color: Picks the outer color of the glow.
  • Range: Sets the gradient position between the two glow colors.
  • Horizontal: Sets the amount of horizontal glow.
  • Vertical: Sets the amount of vertical glow.
  • Crop: Sets whether or not the object is cropped at its original boundaries.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Radius, Brightness, Inner Color, Outer Color, and Range.

Overdrive

Creates an animated glow effect by compositing numerous glowing tinted duplicates of the original image. Fine detail is lost, and the highlights of the image are emphasized. You can customize the inner glow and outer glow colors.

Figure. Canvas showing effect of the Overdrive filter.
Parameters in the Inspector
  • Intensity: Sets the number of samples.
  • Size: Sets the radius of the effect.
  • Rotation: Sets the angle of rotation of the collected offsets.
  • Inner Glow: Picks the color of the inner part of the glow. Use the disclosure triangle to display Red, Green, and Blue sliders for more precise color selection.
  • Outer Glow: Picks the color of the outer part of the glow. Use the disclosure triangle to display Red, Green, and Blue sliders for more precise color selection.
  • Crop: Sets whether or not the object is cropped at its original boundaries.
  • Mix: Sets what percentage of the original image is blended with the filtered image.
HUD Controls

The HUD contains the following controls: Intensity, Size, Rotation, Inner Glow, and Outer Glow.
