From Adobe's Julieanne Kost: "You can create your own lens correction profiles to use with Adobe Photoshop CS5 and Adobe Lightroom (for less common camera and lens combinations) using the free Adobe Lens Profile Creator utility available on the Adobe Labs site.
Specifically, Lens Profile Creator characterizes three common types of lens aberrations, namely the geometric distortion, the lateral chromatic aberration and the vignette. The general process of creating a custom lens profile for your lens involves capturing a set of checkerboard images using your specific camera and lens, converting the set of raw format images into the standard Digital Negative (DNG) file format using the Adobe Camera Raw processor, and importing the raw DNG images (or the JPEG/TIFF images if you prefer creating lens profiles for the non-raw workflow) in the Lens Profile Creator to generate the custom lens profile. You could also submit the lens profiles that you have created for your lens from inside the Lens Profile Creator to share with the rest of the user community."
I look forward to giving this a go with CCTV lens/body combinations. It should prove an interesting diversion.
Enjoy.
