My recommendation! when a panorama isn't well-Stitchd, so horizontal or vertical lines don't match perfectly, it is impossible to know whether it comes from a problem of complex distortions that the panorama software can't correct or if it's a parallax problem hence a wrong position of the camera at the entrance pupil. Why you should choose a recent version of your favorite panorama software Next key points: stitching of the panorama
So if you're using them, do look into the setting of the nodal point if you're experiencing stitching problems (or use the ramsac Homography model in Autopano). If you use this software, this problem won't bother you so often. Lens Correction in Camera Raw or Lightroom is often very efficient to correct a good number of optical distortions complicated to stitch.Īutopano Giga 4.4 and PTGui 11.0 are really very good nowadays to get rid of distortions problems. Some horizontal elements don't stitch perfectly. OPTICAL DISTORTIONS ARE SOMETIMES AS IMPORTANT AS THE SETTING OF THE NODAL POINT.Ī stitching problem because of a distortion problem really looks like a problem of nodal point setting. The rest of this page is aimed at those who want to learn more. Here are the key points to remember about optical distortions. If you observe stitching artifacts on your final panorama it's because your lens is too distorted. The justice of the peace? Make an stitching by making sure you have perfectly adjusted the nodal point. Important note! A fault of stitching due to a bad adjustment of the nodal point furiously resembles the same defect of stitching but this time with a strongly distorted objective. Indeed, there are still in 2019 objectives that fit less perfectly than others and it is not due to a bad adjustment of the nodal point but to their "sly" distortions. This is almost completely the case today, in 2019, Autopano or PTGui. Gradually, the panoramic software optimized and integrated these corrections until being able, sometimes, to correct them entirely.
#PICKTORIAL LENS CORRECTION HOW TO#
For a very long time, the panorama software did not know how to detect and correct them automatically and our panoramas had very many stitching artifacts in the overlapping areas. Many objectives distort the images slightly and this is particularly visible on the architectural photos as in the photo opposite. This is due to the shape of your lens, the aspheric lens. There are two reasons why your pictures might not get Stitchd correctly: a wrong setting of the entrance pupil and maybe even more optical distortions of your lens or zoom lens.
