That's a good point, but I don't have that. On <http://wilson.bronger.org/lens-list.txt>, you can review the content of the uploads directory. The names are already changed by writing EXIF data into the filenames. But still, this list is of limited use, and I don't like to advertise it. Note that 40% of all uploads eventually turn out to be unusable. Mostly I get better ones from the original uploader, but not always. Besides, in some cases, the actual lens model is found out only during the calibration. My goal is to have so few uploads pending that a collision is very unlikely. It used to be like that. > I also looked through the older materials on calibration and have > been scratching my head over the illumination of vignetting test > images, how do you get good ones. It is less critical than it seems. A diffuser in front of the lens is always necessary, but in contrast to earlier texts of mine, I now think it can even be paper (if absolutely level of course). The actual ilumination should not cast a visible gradiant of the diffuser but unless somebody points a laser pointer to it, I think this will work in all practical cases.
