Some other lenses, zoom lenses, short focals that were stitched just correctly can now be stitched perfectly. A few Photoshop edits remain but there's no possible comparison with the previous versions and other stitching pieces of software. IT IS NOW POSSIBLE TO STITCH THE GREAT MAJORITY OF SHORT FOCALS ALMOST PERFECTLY.Ĭertain lenses that were impossible to stitch like 14 mm can now be stitched more than correctly, even perfectly. Since the release of the new version of Autopano Giga and Autopano Pro 2.6, one of the major news in my opinion is the introduction in stitching algorithms of a correction of complex distortions often cursing lenses like short focal lenses. You'll find simple pieces of advice to implement to stitch nice panoramas, choose your software, your equipment. So here are a few leads.Ī new part of this guide is now dedicated to you. But currently, these two types of defects don't look alike.Įven if certain pieces of software can very well correct a classic distortion, barrel distortion most of the time and even quite pronounced, numerous lenses are unfortunately cursed with distortions called "moustache distortion" or even "cop hat" which are really hard to correct and put numerous pieces of panorama software on their knees. You know it's a problem of distortions if you're sure of the setting of the entrance pupil. And even if the camera was well placed at the entrance pupil.Ĭaution! when a panorama is badly stitched so the lines are distorted, it's impossible to know a priori if it's a problem due to complex distortions that the panorama software can't correct or a parallax problem hence a wrong placement of the camera at the entrance pupil. Indeed, optical distortions of pictures are often so important that panorama software have a hard time to stitch together two consecutive pictures even for the best of them like Autopano Giga (even the last version 2.6 considerably improves the problem) and PTGui. Here is really the more important edit to realize, before stitching the photos, when it's really necessary. This is due to the shape of your lens, the aspheric lens.
There are two reasons why your pictures might not get stitched correctly: a wrong setting of the entrance pupil and maybe even more optical distortions of your lens or zoom lens.
