In this case you can rely on someone somewhere figuring out the set of parameters (usually called a profile) and posting them online. PTLens has manual adjustments for vignetting and CA.
and (2) Both DxO Optics and PTLens have distortion correction modules for the. If your lens is fixed focal length and the distortion is independent of focus distance (which I think it largely is with the Samyang 14mm f/2.8) then one set of parameters can easily be applied to all images generated by all copies of the lens (that aren't decentered in some way). Since posting the review I have actually added a chip to my lens so that.

That is why I didnt write a full answer, because you would have to look into it yourself. Therefore you need a piece of software/plugin that can do different types of distortion, along with the parameters of the distortion. I just use PTLens standalone, and have read that it is an available plugin for Aperture. You can usually only tune one parameter of the correction so you'll never eliminate the moustache. The reason the Photozone review states that this distortion is difficult to detect, is that most software only offers very simple correction based on radially symmetric distortions based on simple formulas. and thought I'd pass this on.It's very difficult to correct by hand, but very very easy for a computer to correct, given a formula for how the distortion behaves. I did not have made a comparison, but I think PTlens was a bit better than lightroom correction. I've just been using PTLens for many years. I made lightroom profiles (see homepage Samyang review) for the Samyang 14, and the PTLens correction is based on my pictures someone prepared and send the programmer. I have recently written a review comparing the Canon Powershot G7 to the.

If anyone else wants another drone lens' distortion corrected by PTLens, you can send your stills and video to Tom Niemann. This study reports the results of a systematic literature review investigating. Try +1 as a setting to start, and then adjust Scale and Position under the Motion effect to compensate for the moving up of the pixels along the bottom edge of the frame.
If you just want a quick fix for the horizon dropping towards the edge of the frame (right and left), you can adjust Horizontal Decentering (Presets>Video Effects>Distort>Lens Distortion) in Premiere Pro.
#Ptlens review code#
Several years and 30,000 lines of source code later PTLens has evolved from a simple DOS command-line program to an easy-to-use application and Photoshop plug-in that corrects. It all started when I posted the following message in a news group: Nobody volunteered so on September 19, 2002, I released version 1.0 of PTLens. If you want to remove lens distortion using the PTLens plugin, you can open the DNG file in a raw converter like RawTherapee, save a TIFF file, and then open the TIFF file in Photoshop, where you can apply the PTLens plugin. PTLens is the first application to automate distortion correction. Just wanted to say that you can correct the Mavic Air's lens distortion now using the PTLens plugin in Photoshop.įor video, you open your video file in Photoshop, convert it to a Smart Object, add PTLens (Filter>ePaperPress>PT Lens) to the layer, select the camera and lens (Make: DJI Model: Mavic Air Lens: Video) and then render the video.įor stills, Photoshop automatically corrects the lens distortion when opening the Mavic Air's DNG files.
