Panotools from Kekus Digital is a set of five Mac OS X-only Photoshop plug-ins based on Helmut Dersch's Panorama Tools application. Included in the set are LensFix, which corrects geometric distortion and chromatic aberration from many popular digital SLR and lens combinations, and Remap, which can convert full-frame fisheye photos into rectilinear images. Panotools is compatible with Mac OS X versions of Photoshop 7 and CS, as well as Photoshop Elements. A 15-day trial version is available for download, and a full license costs US$39.95.
