from The actual lens correction parameters a, b and c which are used to correct for barrel distortion, pincushion distortion and even wavy distortion. The a and c parameters control more complex forms of distortion. In most cases it will be enough to optimize for the b parameter only, which is good at ...


There are several problems transforming the curvilinear perspective of the wide angle GoPro lens to a rectilinear one. The transformation stretches the image in certain areas and compresses it in others. This lowers the image quality as new pixels are created as approximations and interpolations from the information in the original image. There is also a ...


I doubt there's a hardware solution to this, and if there were one, it's likely to cause a decrease in image quality. Software is your solution, here. From the DJI website for the Phantom 2 Vision minidrone: A lens profile released by Adobe for DJI Phantom 2 Vision's camera can be used to remove lens distortion DJI keeps it here: ...


Try using Darktable instead. The 'lens correction' module shown above should help remove the fisheye effect. If your lens is in the database it can automatically make the correction, or if not you may adjust manually.


The package RawTherapee, since version 4.0.9, will use Adobe .lcp profiles. Please see: Support for Adobe LCP lens correction profiles It is available in the Ubuntu repositories.


Unfortunately, Aperture doesn't have built in automatic lens distortion- you need to buy the plugin PTLens, ~$25.


Simply put, the distortion isn't so much a result of the lens as it is the angle of view. Since you are seeing things that are almost directly out to the side, you are seeing them from the side rather than the front. You can apply a rectilinear correction, but doing so will result in forcing the perspective to not match up with what you are actually seeing ...


I found the following instructions which helped me achieve what I was looking for: For my lens I found the following parameters useful: Lens type: Full frame Fisheye Focal length: 9mm Focal length multiplier: 2.2 ...


Hard to see what you're asking. A given focal length and composition will always have the same character due to laws of optics. You're always going to see that effect, it has nothing to do with the subject. If you're asking whether some people look good that way, then yes of course they do — but that's your responsibility as the artist to make that happen. ...
