Most of the projections make the overall image bulge outward at the top and bottom. I'm pretty sure they are magnifying area at the top and bottom relative to the middle. Some of them have vertical lines pretty close to vertical. Turning the whole project sideways (which was easier than I had expected, just change the roll value on the anchor image and recalculate) did the reverse bulge, out in the center and had vertical lines very far from vertical. Transverse Mercator just exaggerated all the faults of turning the project sideways (with the more common projection choices): The overall panorama bulged in the middle and vertical lines exaggerated that bulge. Stereographic has vertical lines bulge out, but not nearly as badly as I get from turning the project sideways. There isn't actually a lot in the panorama above or below the middle image. The top and bottom images overlap each other a lot in addition to each mostly overlapping the middle. The original middle image isn't very distorted (vertical lines bulge inward just a very small amount). So I would expect to be able to get a less distorted panorama. But I don't know about projections, so I don't know what to try. It seems like there must be some metric wrong in the exif and/or some user error to have the whole panorama this distorted compared to the middle image alone, which covers most of the total. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
