Adobe has posted a second prerelease of its Lens Profile Creator utility, which generates custom lens profiles for use with the Lens Correction tool in Photoshop CS5. As Adobe puts it, “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”. These optical aberrations include geometric distortions, corner shading and chromatic aberrations. You first need to capture a set of chequerboard images with your camera (provided as part of the application package), which you can then feed into the Lens Profile Creator utility. Today’s update fixes several reported issues in the initial build, Adobe says.
