Adobe has released Camera Raw 7.1 and Lightroom 4.1 with the same raw processing updates for both, and with a corresponding update to DNG Converter, the utility that among other things can bring the latest camera raw support to versions of Photoshop before Photoshop CS6. All are free updates for current licenses of the software.
Along with the usual bug fixes and added support for new cameras (including the Canon EOS 5D Mark III and EOS 1D X, Fuji X-Pro1, and Nikon D4/D800/D800E) and new lens correction profiles, there are several new features that you can read about in a post at the official Lightroom Journal.
Probably the biggest new feature is the powerful new set of color fringe correction controls. You’ll find them in the Defringe section of the Color tab under the Lens Corrections tab, and you can learn how to use them in a very informative blog post at the Lightroom Journal.
In the release candidate version of Lightroom 4.1 I had experienced a problem with edges looking jagged when profile corrections were turned on, a problem discussed in the forums. After I installed this final version of Lightroom 4.1, the files with that problem appear to be fixed.
To download the update, go to:
To update Photoshop and Camera Raw directly, start Photoshop and choose Help > Updates.
To update Lightroom, start Lightroom and choose Help > Check for Updates. If you bought Lightroom through the Mac App Store, the update may take a longer to become available there because it has to wait for Apple approval.
