For focal lengths greater than 35 using this particular lens, I can turn off this correction, as it makes no difference to the final image.Ī quick tweak of the Vertical Perspective and Rotate settings fix the perspective in a few seconds. Since I normally only use the one camera/lens, I just need to type in the focal length. Note that the Barrel-Pincushion correction default to the last settings here, but the standalone and PhotoShop versions can automatically determine the Make, Model, Lens and focal length if you wish. Normally this opens full-screen, so you can get a good look at your image, but I've reduced the window quite a lot here.

It displays the sort of distortion you get from shooting at a wide angle (the curved edges) and perspective distortion from having the aim the camera upwards to get the whole thing in the frame.Īlthough in the past I've used the standalone version to batch-process all the images for a particular project, now I can do all the work inside my imaging software - PTLens is available from the Effects menu. Here's a typical image in Picture Publisher. I still find it easier to work with the plugin though, as my camera/lens combination is normally the same, and I can read the focal length from the image properties and enter it into the plugin. However the standalone version picks this up, and I understand that PhotoShop does so as well. One problem with the Picture Publisher/PT Lens plugin combination is that Picture Publisher doesn't retain the required photo meta-data, so the plugin can't determine the camera, lens, and focal length. So now all the preparation work can be done inside Picture Publisher, saving me a lot of work. I've always used the standalone version, as I don't use PhotoShop, but I'm very pleased that the PT Lens plugin works in Picture Publisher, which handles some, but not all, PhotoShop plugins. PT Lens, like ImageAlign Pro, comes in both a standalone version and a PhotoShop Plugin. The new PT Lens has now incorporated perspective correction, so it is a nice cheap alternative to ImageAlign Pro. Instead, I found a new version of PT Lens, no longer free but good value at US$25. PT Lens uses a database of camera/lens profiles to automate the correction process, so last month when I was testing a new lens I bought for my son, I went looking for a profile for the lens.
#PTLENS PHOTOSHOP PRO#
My original tutorial discussed my workflow which started with a free tool called PTLens, which automatically corrected the barrel distortion created by using a wide-angle lens, and then moved to ImageAlign Pro to correct the perspective. Which is a shame, really, because ImageAlign Pro was a great tool created here in Godzone, and I still find it indispensable for perspective correction. For $25, you can also purchase the licence via PayPal, which is a pretty good deal in my opinion.I had previously covered a couple of tools I used to prepare photos for textures, but I removed this as one of the tools is not now available.
#PTLENS PHOTOSHOP TRIAL#
The plugin is available to download as a trial version (both Windows and Mac) that has complete functionality, but will only process 10 images. PTLense Photoshop plug-in is a simple and powerful plug-in which also works as standalone software and you will definitely find it useful when working with your fisheye images. Alternatively, you may use the lens correction options in Adobe Photoshop or Lightroom 3, but these offer limited control over the image. You may simply crop the image but that way you will lose a considerable amount of picture and the image will still remain distorted.
#PTLENS PHOTOSHOP FULL#
If you are shooting with an 8mm fisheye lens on a DX format cameras, you will always have dark corners in your picture that require adjusting in order to de-warp the image to a full frame, just as a ‘full frame fisheye’ such as 10.5mm would do. FX format cameras, on the other hand, have a bigger sensor and therefore will produce a fully circular image. Correcting Fisheye images with PTLens Photoshop plug-in.ĭue to the size of the sensor in DX format cameras, an 8mm fisheye lens will not produce a circular image.
