What is Parallax?
(PanoGuide). The impact of parallax errors differs per scene: for a landscape panorama, with no objects close to the camera, a limited amount of parallax is usually not a problem and such a panorama can easily be taken handheld. But for panoramas of room interiors even a small misplacement of the camera of just one centimeter or inch will result in clearly visible stitching faults. Creating a good interior panorama is therefore impossible without using a tripod and properly calibrated panoramic head. In contrast to (e.g.) barrel distortion, correcting for parallax faults in software is impossible. This is not a limitation of PTGui but a physical limitation. If you must stitch images with parallax, the best you can do is to mask the faults after stitching by placing the seams appropriately (see our post processing tutorial) but this can be a lot of work and often does not lead to perfect results. Parallax problems lead to overall high control point distances: if you have many control po

Parallax is most significant when GOES observes opaque clouds at high altitudes. Here is a parallax diagram created by Patrick Dills/COMET after Carl Weiss’ original figure which appeared in a NESDIS technical note back in 1977.
