ePaperPress PTLens is software created for the first time Thomas Niemann, which corrects the distortion introduced by the camera lens: pincushion or barrel (barrel), vignetting, chromatic aberration, distortion of perspective. PTLens available as a standalone application or plug-in for Adobe Photoshop.
PTLens is the first application to automate the correction of distortion. All started on 20 August 2002 when the newsgroup following message appears:
I need a program with a batch process that reads the EXIF information of JPEG
file, finds the closest match in the table, and automatically corrects distortions.
No one responded, and September 19, 2002 Thomas Niemann released version 1.0 PTLens. Several years of work and 30,000 lines of source code of a simple DOS program with the launch from the command line later turned into PTLens application and Photoshop plugin that corrects distortion, vignetting, chromatic aberration and perspective. Table is made up of more than 2,500 individual calibration is much more than in any other application .
To date PTLens the first and the best program for correcting distortions (geometric distortion) introduced imperfection optics camera lenses, it is possible to control the white balance.
The program uses the raw data from the EXIF, which simplifies the setup for non experienced users. If EXIF damaged, not complete or is missing, it is possible to manually specify the brand of the camera and lens (if removable). PTLens familiar with a variety of models of cameras and interchangeable lenses, an extensive database on the lenses. Full list of supported profiles can be found here.
PTLens will be extremely useful for both novice amateur photographers and professional photographers.

Profiles for Cameras with Fixed Lenses
If an entry indicates JPEG: no distortion then no correction is necessary for JPEG images. This is because distortion is corrected in cameras firmware and no calibration (or profile) is necessary. If the camera has the capability to shoot Raw images calibration will still be required as Raw images represent unprocessed sensor data. Calibrated profiles are based on images submitted by users.
With the advent of in-camera distortion correction some cameras are calibrated Raw only. These calibrations are suitable for raw converters that do not correct lens distortion.
