You can now download Adobe Lightroom 5 Beta for free and try out some of the new features from Adobe.com. It's a working Beta version that will work until the final release is ready. As an avid Lightroom user I'm always excited to see what the improvements and new features are in each new version. The major improvement this time is in the software's editing module, you can now do pretty advanced selective area adjustments and cloning much faster. This is pretty sweet news for all my fellow wedding photographers!
Some of the new major features are:
+ Advanced Healing Brush
+ Radial Gradient
+ Smart Preview
And some other smaller improvements.
Expect the final version to be out in a few months and to have some additional improvements.
