Adobe Photoshop Lightroom 4 Update

Adobe Photoshop Lightroom software is essential for today's digital photography workflow. Now you can quickly import, process, manage, and showcase your images -- from one shot to an entire shoot.

With Lightroom 2, you spend less time in front of the computer and more time behind the lens.
What's new in this version:
Correction that prevents artifacts from being introduced to Process Version 2003/2010 photos that have Fill Light adjustments applied. Correction for raw image support for the Samsung NX300 camera. It is recommended that Samsung NX300 customers clear the Camera Raw cache (Lightroom-> Preferences -> File Handling -> Purge Cache) and rebuild their previews.
