Adobe Lens Profile Creator and Downloader

I saw this in a Ben Willmore class yesterday. Pretty cool!

“Lens Profile Creator is a free utility that enables the easy creation of lens profiles for use in the Adobe Photoshop® family of products, such as Adobe Photoshop CS5, the Photoshop Camera Raw plug-in and Adobe Photoshop Lightroom®. A lens profile describes the types of optical aberrations that exist in a particular lens and prescribes how to correct the lens distortions in an image captured from the same lens.”
