Hi everyone! I have run into a problem using hugin's stereographic projection. If I load an image and indicate that I have used a stereographic lens and a hfov of 90 degrees (roughly what you'd get using e Samyang 8mm fisheye in portrait orientation and a good round number to illustrate the problem), the hfov the image actually occupies is more like 95 degrees. This occurs only if I use the stereographic setting for the lens; if I set it to full format fisheye it is precisely 90 degrees as I feel it should be.
Also, if I extract a section from the full sphere using the full format fisheye as the target projection, with a horizontal angle of 90 degrees and an image size of, say, 1000 X 1500, and then reimport the resulting image into my project as full format fisheye image with 90 degrees fov, it fits perfectly. If I do the extraction using stereographic target projection and reimport, the image is way off what I anticipate (since it's now about five degrees wider). The exported stereographic image has the 90 degrees all right, so the problem seems to be on the image loading side. I'm not sure what to make of that - could something be amiss with the stereographic projection? Does anyone get the same effect? I have illustrated the problem with a simple sample image, but I don't know how to post the image to the group (new here), so if anyone is interested in my illustration, would they please enlighten me about the required procedure? (Would be some tiffs and a pto) I am usin hugin 2010.1.0.5118 for Windows, maybe it's a known problem?
