Lens Corrector PRO is a Photoshop (or compatible) plugin/filter targeted
towards professionals (although
equally useful for hobbyists) for correcting camera lens distortion.

Lens Corrector PRO v1.1 Featureset:
- Improved, faster lens correction algorithms.
- Ability to specify axis centre for lens correction and all advanced image
processing controls.
- User selectable crosshair colors and icons for clearer visual
representations.
- Ability to specify the axis centre in the preview window with the mouse,
as well as through sliders.
- User selectable "Out of Range" color for marking and easily identifying
invalid pixels.
- Multiplier for extreme lens correction distortions.
- "Scale to Window" feature intelligently fits lens corrected images to
window size in order to minimize scale loss.
- Horizontal and Vertical precision image scaling.
- Horizontal and Vertical precision image skewing (shearing).
- Horizontal and Vertical precision image perspective adjustment.
- Horizontal and Vertical precision image curved tapering.
- Horizontal and Vertical precision image shifting.
- Precision image rotation.
- Horizontal and Vertical image flipping.
- Rendering statistics for preview redraws and estimated final renderings.
- Grid display for clear and precise lens correction visualization.
- Ability to custom define grid, as well as overlay over source image for
even more precise lens correction visualization.
- Ability to overlay grid lines only, cells only, both or none.
- "Conform to Fisheye" transformation algorithm with multiplier for extreme
fisheye distortions.
- Horizontal and Vertical polar correction for polar pinching compensation.
- Ability to output individual color channels.
- Sub-pixel filtering (Nearest Neighbor, Bisquare, Bicosine, Bilinear,
Bicubic) for clean, sharp and precise renders.
- Presets for various common camera lenses and their correction settings.
