Lens Distortion

In the Camera Lens range of effects, the Lens Distortion effect simulates the
bending of an image through different shaped lenses, distorting the image in
various ways. The lenses can emulate spherical and trapezoidal lenses as well as a
combination of the two.
To apply the Lens Distortion effect:
1. Select Photo - Lens Distortion.
2. Select Retain all image content if you
wish to keep the entire distorted image
within the bounds of the original
dimensions of the document. You may
also wish to select a background color
where the image edge becomes concave
and forms a gap between itself and the
document edge. Leaving this option
cleared will cause the document to
increase in size and proportions.
3. To turn the image around, set the
rotation angle to the desired degree. You
can set the direction as clockwise or
counterclockwise.
4. For Trapezoidal distortion, set the
center by dragging the X icon instead.
Again, you can use the sliders to set the
vertical and horizontal distortion.
5. Adjust Spherical distortion, set the
distortion center by dragging the O icon
over the preview image. Use the slider
to set the vertical and horizontal degree
of distortion. Adjusting the sliders left
makes the image concave, while going
toward the right makes it convex. To
adjust Spherical distortion, set the
distortion center by dragging the O icon
over the preview image. Use the slider
to set the vertical and horizontal degree
of distortion. Adjusting the sliders left
makes the image concave, while going
toward the right makes it convex.
