The S_FreeLens filter comes from the Emmy award winning Boris FX Sapphire filter set.

Diffusion/Blurs.

To select a preset, pick one from the Presets window.

Offsets the lens horizontally or vertically. Note that the image moves opposite to the lens motion.

Rotates the lens left or right about a vertical axis.

Rotates the lens up or down about a horizontal axis. You can use Tilt X and Tilt Y together to rotate about an arbitrary diagonal axis.

Moves the lens away from or toward the camera.

Rotates the lens about the line of sight. In a real lens, this would rotate the iris, so the rotation is perceived as a rotation of any defocus highlights in the image.

Controls the amount of lens telescoping while applying Tilt X and Tilt Y. Increase for more 3D perspective.

Determines the method for accessing outside the borders of the source images.

Gives black beyond the borders.

Repeats a copy of the image.

Repeats a mirrored copy. Edges are often less visible with this method.

If enabled, the image is adaptively filtered when it is resampled. This gives a better quality result when parts of the image are warped smaller.

Scales the overall amount of defocus blur and highlights.

Adds some chromatic aberration around the edges of the image. Red and blue wavelengths of light refract differently in real lenses, producing fringes of color where the rays strike the lens at oblique angles.

The relative height of the iris shape. If it is not 1, circles become ellipses, etc.

Selects the type of output.

Shows the final output.

Shows the depth map generated for the current lens position and orientation.

Determines the shape of the simulated camera iris.

Round.

Triangle.

Square.

Pentagon.

Hexagon.

Seven sided polygon.

Eight sided polygon.

Nine sided polygon.

Ten sided polygon.

Eleven sided polygon.

Twelve sided polygon.

Modifies the shape of the simulated camera iris. A value of 1 produces a circle, while 0 creates a flat−sided polygon with a number of sides defined by the Shape parameter. Less than 0 causes the sides to squeeze inward producing a star shape, while a value greater than 1 causes the corners to squeeze inward, creating a flowery shape. This has no effect if the Shape is set to Circle.

The amount to increase the luma of the highlights in the image. Increase this parameter to blow out the highlights without affecting the darks or midtones.

The minimum luma value for highlights. Pixels brighter than this will be brightened according to the Boost Highlights parameter.

Enables distortion.

Controls whether distortion is adjusted by the lens or set manually.

Distorts the image radially for barrel or pincushion.

Scales the distortion in the horizontal direction.

Scales the distortion in the vertical direction.

Enables light leak.

Controls whether light leak is adjusted by the lens or set manually.

Scales the intensity of the light leak elements.

Controls the aspect ratio of the light leak elements.

Scales the width and height of the light leak elements.

Amount to vary the size from one light leak element to the next.

Rounds the corners of the light leak element.

Controls how many edges there are for each light leak element.

Controls how many light leak elements there are.

Controls how far apart the light leak elements are.

Controls the color at the outer edge of each light leak element.

Controls the color midway from the center to the outer edge of each light leak element.

Controls the color at the center of each light leak element.

Moves the location of the Mid Color between the center and outer of each light leak element. Set to 0 to place the Mid Color at the center or 1 to place it at the edge.

Blurs the color gradient of each light leak element. Increase for a smoother gradient or decrease for sharper bands of color.

Scales the brightness of the glow which is applied to the entire image after combining the light leak with the background.

The width of the glow. Increase for a softer glow and decrease for a sharper, brighter glow.

Parts of the image that are brighter than this value get glowed.

Enables vignette.

Controls whether vignette is adjusted by the lens or set manually.

The opacity of the vignette.

Determines how square the vignette shape is. Set to 1 for a square or rectangle shape. Set to 0 for a circle or ellipse. Values in between give rectangles with rounded corners by varying amounts.

Distance from the center to apply the vignette.

The relative height of the iris shape. If it is not 1, circles become ellipses, etc.

The relative horizontal size of the vignette shape. Increase for a wider shape or decrease for a taller one.

Rotates the iris shape.

The width of the vignette's soft edge. Larger values create softer, less visible edges.

If 0, a linear gradient is used across the screen in the soft edge area. Increase this value to use a smoother S shaped curve for interpolation which can reduce the visual perception of the gradient's start and end locations.

The color of the vignette.

Blurs the borders of the image in addition to darkening them.

If checked, the center (undarkened) area of the image is blurred instead of the border.

Scales the brightness of the image. To see only the vignette, set this to zero.

Determines how the vignette is combined with the Source.

Composites the vignette over the image.

The vignette color is multiplied by the image. If the Color is not black, this will selectively colorize the vignette area.

The vignette color is added to the image. This will have no effect if the vignette color is black.

The vignette color is combined with the image using a screen operation. This will have no effect if the vignette color is black.

The inverse of the vignette color is subtracted from the image. Inverse means white for black, yellow for blue, and so on. This mode looks similar to Mult, but a bit more severe. It crushes the blacks, but retains highlights. This will have no effect if the vignette color is white.

Shows the vignette pattern without the image. The output will be white where the amount of vignetting is greatest, for example, where the image would be darkened completely.

Shows the inverted vignette pattern without the image. The output will be white where there is no vignetting, for example, where the image would not be darkened at all.
