bradtem wrote:I even more want an option to say "I shot this on a tripod and/or pano head." What this means is APP would strongly resist any solution where the images are not all tilted the same relative to one another.
bradtem wrote:With heavy lenses, the pano heads do bend so they are not always straight up and down but they are always the same tilt in their circle, and APP should strongly reject CPs which imply anything otherwise.
bradtem wrote:I hate shooting on a pano head and having APP present this warped distortion as that happens a lot.

bradtem wrote:The tripod is generally level as well (with bubble level) but as we know even bubble level will show some slight tilt in a big pano.
bradtem wrote:Anyway, in spite of this, APP sometimes screws is up because it is not realizing that the images are regular, and thinks they might have more arbitrary and varying roll or pitch when the ones in a row are all the same.
bradtem wrote:It does this because SIFT sometimes will match up on items displaced by parallax -- yes it happens even on a pano head -- or because they moved. In particular if it happens to get clouds or people it will match and get confused.
bradtem wrote:And this is the problem. Yes they feature matching makes it look like the image has a different roll, for example.
bradtem wrote:I want to tell it, NO, it never does. If you find a match that makes you look for a solution that implies a different roll (or different focal length etc.) that match is probably wrong, so discard or downrate those CPs.
