Adobe’s Julieanne Kost has created three videos which detail 25 new minor refinements in Adobe Photoshop Lightroom 3 that could impact your workflow, these clips are available here. Writing on the Lightroom blog, developer Tom Hogarty said, “We’ve come a long way since our very first public beta on January 9th 2006 at Macworld.(We didn’t even have a crop tool in the first release!) For this latest release we went back to the drawing board and revisited what we believe are the fundamental priorities of our customers: Performance and Image Quality. “Lightroom has been stripped down to the “engine block” in order to rebuild a performance architecture that meets the needs of photographers with growing image collections and increasing megapixels. The raw processing engine has also received an overhaul right down to the fundamental demosaic algorithms that now allows unprecedented sharpening and noise reduction results.” Lightroom users can organize, enhance, and showcase their images all from within a fast application that’s available for Mac and Windows. Some of the new features include:

Brand new performance architecture, building for the future of growing image libraries State-of-the-art noise reduction to help you perfect your high ISO shots Watermarking tool that helps you customize and protect your images with ease Portable sharable slideshows with audio—designed to give you more flexibility and impact on how you choose to share your images, you can now save and export your slideshows as videos and include audio Flexible customizable print package creation so your print package layouts are all your own Film grain simulation tool for enhancing your images to look as gritty as you want New import handling designed to make importing streamlined and easy More flexible online publishing options so you can post your images online to certain online photo sharing sites directly from inside Lightroom 3 beta (may require third-party plug-ins)
