Epaperpress PTLens v7.6.1 StandAlone and Plugin for Adobe Photoshop | Win32 | Size: 1.04 MB
PTLens is Windows software that corrects lens pincushion/barrel distortion, chromatic aberration, and vignetting. PTLens is available as a standalone application or Photoshop plug-in. Both the standalone application and plug-in versions of PTLens run under Windows 2000 or Windows XP with a monitor resolution of at least 1024x768 (DPI 96). The plug-in version works with Photoshop version 6 and above and all versions of Photoshop Elements. Although PTLens is compatible with Paint Shop Pro and Irfanview, camera make, model, lens, and focal length must be manually specified as they do not furnish EXIF information to plug-ins.
In 2001 I had an idea. Why not read EXIF data and use this information to lookup calibration coefficients in a database. Then simply press a button to correct distortion. The year 2002 marked the first release of PTLens. To date there are over 350 lenses in a database that consists of over 2400 separate calibrations. What started as a germ of an idea has evolved into a fast streamlined application that supports a wide variety of cameras and lenses.
