Adobe Photoshop Lightroom 4.4 Release Candidate

New camera and lens profile support for Lightroom users

Welcome to the Adobe® Photoshop® Lightroom® 4.4 release candidate on Adobe Labs. A "release candidate" label indicates that this update is well tested but would benefit from additional community testing before it is distributed automatically to all of our customers. The Lightroom 4.4 update includes support for many new cameras and lens profiles.

The Lightroom team would like the community to help verify the quality of this update through normal usage as this will ensure that the application is tested on a diversity of hardware and software configurations not available internally at Adobe.
