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.
- All DSLR cameras with interchangeable lenses.
- All DSLR lenses except fisheye lenses (they don't need calibrating).
- Non-DSLR cameras must have a Preview (it says "Preview" in the title) or Full Review (it says "Review" in the title) at dpreview.com. Otherwise there would simply be too many cameras and lenses for one person to calibrate. I do make exceptions. Especially for calibrations that I can apply to more than one camera.
- Wide angle or telephoto converters for any of the above.
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.
