Downloaded the first beta of Adobe's new photography workflow software today. Obviously Adobe are trying to limit the damage of Apple's Aperture software.
Lightroom brings a whole new interface design, different to ayhting I have seen from them in the past and actually feels very influenced by current trends in webdesign. On the feature side of things Lightrooom seems fairly underdeveloped, with great colour tools including an excellent grayscale mixer. There are also nice controls for slide shows. However, I have yet to find a straightening tool or a crop tool, two essentails for me.
One feature that I really like is that when importing photos Lightroom allows you to manage them from their current location or bring them into its own library.
