I found a better set of tutorials, suggested by the maintainers of the lensfun database, so I think it's probably better.<br /><br />http://lensfun.berlios.de/calibration/<br /><br />In particular, the first tutorial on that page includes a video tutorial:<br /><br />http://vimeo.com/51999287<br /><br />This video tutorial says that you need to take a picture of something with straight lines *at least 8 meters away* (in the HTML doc, it says 1 meter may be enough, but our photos of the paper are definitely too close), since distortion can be weird at close range. Did you try with the meter sticks?
