Today Adobe released the new version 2.0 of popular Lightroom product, for cataloging and developing images.
In the Review section of this site, you will find a detailed review of this version: link.
Also the new 4.5 version of Adobe Camera Raw (Photoshop module for developin/treatment of RAW images) has been released, as always, since Lightroom upgrade and ACR upgrade share the same engine. But notice: not all functions available in the Develop module of Lightroom are available in ACR 4.5, that can just import some of the new features of Lightroom (like local or gradient corrections).
ACR 4.5 adds compatibility with Lightroom 2 and a couple of new cameras supported (Olympus E420 and E520).
Main additions in Lightroom 2 are localized corrections and secondary monitor support, but look at our review for full information.
