Adobe Lightroom 4.1 release candidate 2 is now available for download from Adobe Labs.
This release includes new Defringe controls to help address chromatic aberration, and the ability to read 16-bit, 24-bit, and 32-bit HDR files.
Defringe is available as part of the Lens Correction panel, as shown below.
What exactly is a color fringe correction? Well, rather me try to explain I’ve linked to any excellent tutorial written by Eric Chan (Lightroom and Camera Raw engineer)
