Well, a rectangular projection can only display images with <180 degrees field of view (and 120 degrees for practical use), so for this projection, the FOV field needs to be modified. This is a mathematical restriction, so it can't be circumvented. I guess you didn't realize this? This is exactly what Hugin will do when you switch from a Panini projection with a large FOV (>180) to rectangular. Nothing strange about that really. -- Bart -- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
