Maximum PC takes a look at the newly released Photoshop Lightroom 5.0 Beta. And goes through new features, like the improved healing brush, the upright tool, the radial gradient tool, and a few others.
I will download if and when I have some time (could be unlikely with a 12 hour a day job coming up soon) as I find Lightroom the best tool to deal with Camera RAW (and yes I have tried Aperature and other than it’s interoperability with iPhoto it is just not as good).
