Based on Helmut Dersch's Panorama Tools, these Photoshop 7 plug-ins can simply be described as versitile, accurate and powerful. The plug-ins, which cost US$39.95 for the set of four original plus the new LensFix, include: * Adjust: for extracting or inserting corrected images to and from panoramas; * Correct: for fixing distortions caused by lens imperfections and scanning misalignments including: radial, vertical and horizontal shift, shear, scale, radial luminance, cut frame and fourier filters; *LensFix: new plug-in that puts a great interface on the image correction functions of Panotools. LensFix includes a database of correction factors for many popular professional and consumer cameras and users can save their own settings to the database for easy retrieval. * Perspective: for changing the viewing angle of an image; * Remap: for converting panorama types including normal, cylindrical QTVR, spherical, fisheye and convex mirror. Barrel and pincushion distortions found in many lenses can be corrected using the radial shift filter that can adjust the red, green and blue channels separately if you wish. What's more, the light fall off that commonly occurs near the edges of wide angle lenses can be corrected with the radial luminance filter.
