For some pictures, I'd wish to fix barrel-distortion and converging lines. Think architecture with a wide lens. For that, I've included ShiftN as external editor which even supports 16bit tiffs.

The good part: It works fully automatic. It corrects perspectives and gives good results.

The bad part: It needs vertical lines to work reliable. No lens database.


Which solution are you using, which advantage would it give?

I use PTLens (which is available for Windows only) for lens distortion, and Photoshop CS3's Lens Distortion filter for perspective correction.

And which one do you like better? How do you include those two in your workflow?

It's not an either/or - you need both for the jobs you mentioned.

PTLens is based around the lens code in Panorama Tools, coupled with a database of coefficients based on camera and lens. This one can be automated, for example via a Photoshop action. Alternatively, you can use the standalone version of PTLens.

For perspective correction, I export the settings to XMP, open the RAW file as a Camera Raw Smart Object in Photoshop CS3 (I wish that Lightroom 1.1 would have added support to do that within Lightroom, but no such luck), then I apply PTLens as a Smart Filter followed by Lens Distortion as a Smart Filter. Save the file in Photoshop and synchronise the folder in Lightroom to pick up the new file and you're done.
