Adobe Photoshop Lightroom software is a digital darkroom and efficient assistant designed for serious amateur and professional photographers. With Lightroom, you can organize, enhance, and showcase your images all from one fast and nimble application that’s available on Macintosh and Windows® platforms.
The Lightroom 3 beta program is available to the public, so that means anyone with an Internet connection can download it and start putting it to the test. You do not need to own (or have tried) a previous version of Lightroom. You can download the beta and use it until the product expires. The current Lightroom 3 public beta 2 will expire on June 30, 2010.
