Apologies for how long it took to get back to this; it was a fair bit of heavy lifting and life got in the way...
Details are in https://github.com/jtniehof/photo (lenses/sd1100), although I wouldn't recommend cloning it, just browse to what looks interesting. If somebody could take a look and make sure it seems reasonable, then I'll make a pull request against lensfun. I set the database up with the SD1100 using the IXUS80 mount and replaced all the values for the IXUS 80 lens. I used 6.02 for the crop factor; 6.02/5.9 seems to be the ratio of ImageWidth to DefaultCropSize The OOC JPG appear to be completely uncorrected, so there is that at least. However the distortion parameters currently in the database are dubious, particularly for 8.3mm, with Rd/Ru = 1.5 at the center of the image! There's a nice tutorial for manual lens calibration, similar to Torsten's screencast but with the new interface, at http://hugin.sourceforge.net/tutorials/calibration/en.shtml . However, I think I got the best results with the automatic tool documented at http://wiki.panotools.org/Calibrate_lens_gui ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
