On Tuesday, Adobe unveiled the finalized 2.0 version of its Photoshop Lightroom software. The post production photography application is the first product developed by Adobe that runs 64-bit-native on Apple's Mac OS X Leopard.

The new 64-bit support allows Lightroom to cover much larger volumes of memory; this will come in very handy for photographers working with amply sized images.

Some find the most important features of Lightroom 2.0 to be its dual-monitor support and the significantly improved printing tools it has been equipped with.

The company is also providing photography enthusiasts with new RAW technology, giving them the chance to access flexible camera profiles, which will lower unexpected modifications of their work. As company officials said, camera profiles represent the "visual starting point for the raw processing workflow, but image preferences vary for every photographer." For keeping surprises to a minimum, Adobe’s camera profiles "closely emulate the visual looks that photographers are used to seeing from their favorite camera," but also allow users to come up with customized profiles, for satisfying a wide range of tastes.

Camera profiles can be downloaded from the Adobe Labs website; they can be used with both Lightroom 2 and Camera RAW 4.5. The recently added tools are compatible with more than 190 camera models.

Adobe Photoshop Lightroom 2 can be found online at the Adobe Store; for the time being three versions have been made available: English, French and German. The Japanese edition is currently being developed. While those who are getting the software for the very first time will have to pay $299, the ones who are only upgrading will be charged $99.
