Adobe has posted a prerelease version of its Lens Profile Creator utility that enables creation of custom lens profiles for Photoshop CS5, ACR 6.1 and Lightroom 3. The process involves downloading and printing a checkerboard test chart from Adobe Labs, and shooting a series of RAW or non-RAW images. These can then be imported to the Lens Profile Creator to generate custom profiles for the Lens Correction feature in Photoshop CS5 and Lightroom 3. Furthermore, these profiles can also be shared via the company's user community.
