Have you gone through the tutorial yet: http://hugin.sourceforge.net/tutorials/calibration/en.shtml and/or http://wiki.panotools.org/Calibrate_lens_gui

The image doesn't have to be anything special, just go outside and take a picture of something with known straight lines.  In my case I just took a picture of the security bars on one of my windows.

You can also make a grid or star burst pattern with the GIMP and then take a picture of your screen.

To calibrate a lens Hugin wants a picture with straight lines. Cool; I fed it one and it found two on X and one on Y.  believe it would be better to have more. I want an image of a starburst that radiates to the edges of the paper. I spent about half an hour looking but the webpages that had one I liked wanted you to sign up for something. Does anyone have something I am talking about>?
