ePaperpress PTlens Plugin

Hi Folks,

Has anyone used the PTlens plugin for photoshop? It uses the panotools library coupled with a set of specific lens profiles to automatically correct for lens defects.

I downloaded the package of profiles and was pleased to see that it has specific profiles for the popular DSLR's coupled with lenses we use: 17-40, Sigma 15mm fisheye, Sigma 12-24, etc.

For example, I shot a lot of images on the shark trip using the Sigma 12-24DX lens. The PTlens plugin automatically corrects for chromatic aberration, barrel distortion, and vignetting. By clicking on and off w/ the preview, I an see the effect - it's subtle but it's definitely doing something.

You can download the free software at www.epaperpress.com:

It works very well. I use it for correcting distortion from the 15 FE and the 16-35L.

Helped with the reception shots of my wedding that were done with the 12-24!

Hi Stu,

I emailed the author of the program Thomas Nieman asking if I can help do some custom profiles. I think we need a profile for the lens AND DOME combination together. I found out that his profiles are not made for close focus wide angle also - something to consider. Here's an excerpt from Thomas's email:

"Many of your images are taken somewhat close-up. So, maybe this is the distortion you are seeing ... even after correction with PTLens. As a rule I don't correct for distances other than 50 feet... that would be too much work for one person."

Cheers
