Adobe Photoshop Lightroom for Mac and Windows lets professional photographers import, manage, enhance and showcase large numbers of digital photographs. Its foundation is Adobe's own Camera Raw technology, with support provided for a vast array of native raw file formats, as well as JPEG and TIFF. Imported files can be converted to Digital Negative specification (DNG) format or renamed and sorted by folder or date. It also provides presentation capabilities for showcasing images in print or via dynamic slideshows, interactive web galleries and photo-sharing sites.

Adobe claims Lightroom 3, with a focus on performance and image quality, has been redesigned to more efficiently manage photographers' ever-growing image libraries, and improve responsiveness via an improved processing engine. In the Library module, a rebuilt import system is designed to make bringing photos into the application more intuitive. Users can now specify the source and destination of their images, and save common processing, metadata or destination settings as reusable presets. Collections can now be posted on photo-sharing sites, with Flickr users having direct access to their accounts from within Lightroom, which allows them to drag and drop images directly into their Photostreams. Flickr Pro account users can automatically synch their images and view comments made on Flickr directly within the Library. This functionality can be extended to additional sites by adding them as new plugins, once they become available.

In the Develop module, an overhauled processing engine allows users to create the highest quality images. Improved Capture Sharpening and Color Noise Reduction tools provide superior results while still preserving an image’s edge detail and contrast. A new Grain tool adds a film-style grain to images, and two new Vignette modes help photographers get a more natural look. Lightroom 3 beta also offers advanced output options, including the ability to export slideshows as videos with audio and title screens that can be posted to video-sharing sites or optimized for mobile media. New watermarking capabilities enable photographers to embed text or graphic information directly on an image and then adjust the size, position and opacity. In addition, photographers can customize print layouts and save settings for future use, giving them refined control over their images.

Adobe Lightroom 3 beta for Mac and Windows can be freely downloaded on the Adobe Labs site, with the download having an expiry date of April 30, 2010.
