You can correct barrel, pincushion, and fisheye distortion in digital photographs. In barrel distortion the photo appears to bulge outwards from the center. In pincushion distortion the photo appears to shrink inwards toward the center. In fisheye distortion, the photo appears to bulge outwards from the center, as if the photo were wrapped around a sphere. Barrel, pincushion, and fisheye distortion are common in photos that were taken with wide angle or zoom lenses.
You can save your settings as a preset for future use.
