![]() By applying a not appropriate "Lens Profile" for correction, the initial classical simple "barrel" distortion may subsequently become a more complex wavy distortion that the panorama software cannot fully compensate for.Ī short test with images that were shot by a Canon EOS 5D Mk2 involving Stitcher 2009 Unlimited, PTGui Pro 9.0.3 and AutoPanoGiga 2.5.0 was performed to check if the hefty distortion quite specific to the Samyang 14 mm lens can be supported by these popular programs during detection, optimization, warping and stitching. This can happen typically when the photographer uses the "Lens Profile" of a similar lens when there is no profile actually available in the software data base for his peculiar third-party lens. After correction or during the conversion of the RAW image file.APS-C) and because of the image coverage cropping, only the center part ot the distortion is visible and it thus looks like a simple barrel distortion. It might even be the World record holder in this category! On a smaller sensor format (e.g. The Samyang 14 mm is typical of that kind of lens when it is mounted on a full frame DSLR camera. ![]() Coming from the lens: there shall be a hefty mustache distortion on the source images.The irregular type of distortion can eventually be encountered at different steps of the imaging process: More precisely it is thus necessary to find the most appropriate set of values for the coefficients of the polynomial. The individual image correction that is elaborated by the program before warping needs then to compute a multi-order polynomial correcting function. That could be however not the case if the distortion is actually not so regular and when straight lines in the object space look like a "moustache" especially on the edges of the image. Generally this is not a big problem since any good panorama software can easily correct this "simple" type of distortion and there is no real hurdle to overcome with suficient care from the user. Many UWA suffer from a big amount of "barrel" distortion. We can observe that all Ultra Wide Angle (UWA) rectilinear lenses are affected with some negative distorsion. You can find it as a Lightroom plugin.Samyang 14mm and stitching software How do different panorama software fare when they are challenged by the distortion of an Ultra Wide Angle. This software is perfect if you usually work with Adobe Lightroom. It also offers multiple editing tools to correct flaws and enhance your pictures. PanoramaStudio allows you to export interactive panoramas to HTML5. This software offers interactive tools that allow you to add hotspots to panoramic images and create virtual tours. The latter offers a few more options, like support for ultra-wide-angle and fish-eye lenses. PanoramaStudio is photo stitching software available for Windowsand Mac. And it’s also good if you are not looking to control every aspect of its creation.Ī demo version of this photo stitching software is available for free.As a standalone, AutoStitch is available for Windows and Mac OS X. AutoStitch is ideal for the photographer who doesn’t do too many panoramas. The downside to this is that if you do want to make individual adjustments, you cannot. Then it pieces them together to create a panorama. AutoStitch selects the images that match up. It requires no user input to sift through images. This photo stitching software is the perfect solution if you want a program that will do it all for you. Autostitch lets you stitch many photos into a seamless panoramic image.
