I would like to recommend Adobe Photoshop Lightroom 2 for everybody who likes to do more with their digital camera pictures.
Text from Adobe's website:
Adobe® Photoshop® Lightroom® 2 software is essential for today's digital photography workflow. Now you can quickly import, process, manage, and showcase your images — from one shot to an entire shoot. With Lightroom 2, you spend less time in front of the computer and more time behind the lens
