Photo enthusiasts take note, as Adobe is rolling out the official retail version of Lightroom 3 today. Available as a public-beta since October 2009, the latest, official version of Lightroom features a brand new processing engine that improves performance and offers an enhanced, easier to use UI. Noteworthy features include: support for DSLR video files, improved noise reduction, lens correction and sharpening tools, and tethered shooting (with select Nikon and Canon cameras). Lightroom 3 is available for both Macintosh and Windows systems with a price point of $299; an upgrade licences retails for $99. You can grab a copy of this latest offering directly from Adobe today, or from a third party retailer in the near future.
