Thanks Jim - that helps! If you would, check my understanding (remember, I'm a bit new to this).
Presently I don't load a lens profile. Hugin gets a bit of a headstart getting a close FOV from the EXIF info but it (and me) have to struggle though a stitch partially because the distortion data for my lens isn't known. We (Hugin and I) eventually (but not always) get a satisfactory (but never perfect) result. This takes longer than I would like it to. My thinking is that I can improve my stitch times and results if I can load an appropriate/accurate lens profile. I just recently discovered that my lens (Nikkor 18-200mm VR-II used locked at 18mm) has particularly poor distortion characteristics. I realize there are better lenses for the job but until my ship comes in, that's what I'm using. ;) Am I on base so far? I'm trying to first determine if my thinking (above) is correct and if so, where/how to get/create a lens profile for my Nikkor 18-200 and Nikon D200. Given the lens and camera are fairly common, shouldn't I be able to find the a,b,c parameters published? I'd still need d,e. Are d,e different for every D200, or, the same for every D200 (holding the lens constant)? If d,e are constant for all D200/18-200 then it appears a,b,c,d,e are just 5 possibly known numbers that if I can get my hands on, I just type them into Hugin and save a lens profile, no? I didn't quite follow what the process is to get a lens profile if I generate it with Hugin. This also makes me a bit nervous because I assume the Hugin-generated lens profile numbers are not perfect and are likely coming from a stitch that's not perfect. Doesn't this spread the imperfection to the next pano that uses the lens profile? Can you comment in just a little more in detail what my best option is - or provide a reference? If I need to generate one with Hugin, how is that done? Thanks Calvin -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
