I understand the concept that the alignment doesn't need to be great: The blending tools can cover up for poor alignment. But I've never seen that work for any of my panoramas. I have sometimes used detailed masks to cover up for poor alignment. But otherwise, poor alignment gives a terrible result. I understand that correct use of a tripod with a nodal slide can give you a collection of photos in which there is zero Translation. But I haven't managed that yet, even with careful adjustment of my nodal slide. I also understand that this issue is much less significant for panoramas in which the subject is very far away from the camera (500 meters or more). But I think the more common case for ordinary photographers has enough translation to require those in the optimization. As for the lens, I noticed the slight barrel shape of the parallel vertical lines in the original two photos of this thread. I don't know whether to consider that a lens characteristic different from the default "rectilinear": The part of such parallel lines that are perpendicular to the point of view are wider apart in viewing angle, and the viewing angle between the lines goes down with the distance from that perpendicular. But those two photos both had the camera pointing up relative to the face of the building. The perpendicular point is at the bottom of the lower picture. So the visible slight bulge in parallel vertical lines looks to me like it is closer to the vertical center of the image, which would definitely be a lens characteristic, as opposed to representing the actual point of widest viewing angle between the lines (which I don't know whether that would also be a lens characteristic different from "rectilinear"). -- 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.
