Squint

Squint imitates the blurring that might result from bad vision or a shaky cameraman. Squint also creates bright light streaks and kaleidoscopic effects like you might see from oncoming traffic in a rainstorm.

### Basic Tab

Ghost Radius

Controls the expansion of the blur. Low values render a thin, visible halo; the original image details, though blurred, are still visible. High values obscure the original image. A zero value results in no ghosting.

Left to right: Increasing Ghost Radius.

Ghost Segments

Breaks the halo into smaller pieces. Higher values yield more pieces.

Left to right: The subtle effect of adding ghost segments.

Ghost Rotation

Controls the direction in which the segments travel. Click and drag within the control box to change the direction, or enter a value between 0 and 360 degrees.

Draw Light Streaks

Select this option to add rays of light that burst from bright areas in the image.

Streak Brightness

Enhances the whiteness of the streaks, making them appear brighter.

Streak Opacity

Controls the visibility of the light streaks. Low values render imperceptible rays. High values create visible streaks and smear colors like a motion trail.

Streak Selection Threshold

Adjusts the level of brightness that the filter recognizes as "bright enough" to radiate streaks of light. Low values allow virtually any area to emit streaks. High values allow only the brightest areas to do so.

Left to right: Increasing Streak Selection Threshold.

Streak Length

Specifies the average length of the streaks.

Number of Streaks

Controls the density of streak placement. High values add more radial streaks, which eventually overlap to render a brilliant glow.

Streak Variation

Increasingly randomizes the direction in which individual streaks point.

Streak Rotation

Controls the direction of the streaks. Click and drag within the control box to change the direction, or enter a value between 0 and 360 degrees.

Random Seed

Controls the random elements of this filter. Click it until you get a result you like.
