Calibration Overview

If PTLens does not support your camera or lens it is easy to determine calibration coefficients for the PTLens database. If your camera meets the following criteria I'll calibrate the lens and enter the results in the PTLens database.

To calibrate the lens I'll need some calibration images. You have the camera and I have the calibration skills. Working together we can calibrate the lens. You take some calibration images and FTP them to my site. I'll download the images, do the calibration for free, and enter the results in the PTLens database for everyone to use. To date over 5000 images from users from all over the world have been sent in for calibration.
