Lens Distortion

Node icon
Transform
spherize

Apply or correct camera-lens distortion, or add bulge and sphere warps.

Lens Distortion bends the image in one of three modes. Lens applies camera-lens barrel and pincushion distortion across the whole frame and can also run in reverse to remove it. Bulge and Sphere are localized warps centered on a point, bounded by a radius.

Modes

Section titled “Modes”

Lens

Section titled “Lens”

The default mode. Amount drives barrel distortion (positive, pushing the frame outward) or pincushion distortion (negative, pinching it inward) across the entire image. The Edge control adds a secondary distortion concentrated in the far corners; giving it the opposite sign to Amount produces wavy mustache distortion.

The Direction toggle switches between Distort and Correct. Correct applies the exact mathematical inverse of Distort, so it can remove lens distortion from a photo or 3D render, not just add it.

Fill Frame (on by default) automatically zooms the result to the smallest scale that leaves no blank borders at the edges, recomputed whenever Amount, Edge, Direction, Center, or the input size changes. Turn it off to set Scale manually.

Bulge

Section titled “Bulge”

The classic spherical distortion: a power-curve push or pinch inside the radius. Positive Amount values push the image outward as if wrapped around a sphere; negative values pull inward for a concave pinch.

Sphere

Section titled “Sphere”

Wraps the image onto a glass-ball hemisphere inside the radius, for a more pronounced fisheye-like bulge than Bulge mode.

Bulge and Sphere share Radius (the size of the affected circle, as a percentage of half the smaller image dimension), a repositionable Center, and a Feather control that softens the boundary of the affected circle so it blends back into the undistorted image.

Lens Distortion

ModeChoice
Default: Lens
  • BulgePower-curve push or pinch inside the radius. The classic spherical bulge/pinch.
  • SphereWraps the image onto a glass-ball hemisphere inside the radius.
  • LensCamera-lens barrel and pincushion distortion across the whole frame.
Amount (%)Number
Default: 25.0 Range: -100.0–100.0
  • Positive: barrel / bulge outward.
  • Negative: pincushion / pinch inward.
Center X (%)Number
Default: 50.00 Range: 0.00–100.00

Horizontal center of distortion

Center Y (%)Number
Default: 50.00 Range: 0.00–100.00

Vertical center of distortion

Radius (%)Number
Default: 100.00 Range: 10.00–200.00
Mode ≠ Lens

Percentage of half the smaller image dimension. 100% covers center to edge; 200% extends beyond bounds

Feather (%)Number
Default: 0.0 Range: 0.0–100.0
Mode ≠ Lens

Softens the boundary of the affected circle. 0% keeps the full effect out to the edge; higher values blend smoothly back into the undistorted image

Edge (%)Number
Default: 0.0 Range: -100.0–100.0
Mode = Lens

Secondary distortion concentrated in the far corners. Opposite sign to Amount produces wavy mustache distortion

DirectionChoice
Default: Distort
Mode = Lens
  • DistortApply the lens distortion.
  • CorrectApply the exact inverse to remove lens distortion from a photo or render.
Scale (%)Number
Default: 100.0 Range: 50.0–200.0
Mode = Lens

Zooms the result around the center. Use Fit Scale to Frame to hide blank borders the distortion leaves at the edges

Fill FrameToggle
Default: true
Mode = Lens

Automatically keeps Scale at the smallest zoom that leaves no blank borders, recomputed whenever Amount, Edge, Direction, Center, or the input size change. Overrides the Scale slider

Edge ModeChoice
Default: Clamp
  • ClampEdge pixels repeat outward, giving stretched edges at the boundary.
  • WrapPixels wrap around to the opposite edge.
  • TransparentOut-of-bounds areas become transparent.

Filter

InterpolationChoice
Default: Bilinear

Resampling filter

  • NearestNo interpolation, so hard pixel edges are preserved. Best for pixel art.
  • BilinearSmooth blending between pixels, with good general-purpose quality.
  • LanczosHighest quality with sharp detail preservation, best for final output.

Display

Show GridToggle
Default: true

Overlay a warped grid in the preview showing how the distortion bends the image. Display-only; never affects the output

The Show Grid overlay draws a warped grid in the preview showing exactly how the distortion bends the image. It is display-only and never affects the output. The center, radius, and feather can also be dragged directly on the canvas.

Usage Tips

Section titled “Usage Tips”
  • Use Lens mode with Direction set to Correct to straighten barrel or pincushion distortion from wide-angle photos before compositing.
  • Keep Fill Frame on so the result auto-zooms past the blank borders that distortion and correction leave at the edges.
  • In Bulge mode, a moderate positive Amount (30–60%) gives a subtle fisheye; negative values pinch for miniature-planet or vortex effects.
  • Raise Feather in Bulge or Sphere mode to blend the distorted circle smoothly back into the rest of the image.
