Adobe Photoshop Lightroom is now Available. Lightroom is a full featured application that allows photographers the ability to manage, adjust, and presenting large volumes of digital photographs. Lightroom and Apples Aperture are the premier software titles for this right now, they blow any other RAW capture handler out of the water. O'Reilly has some good reviews including some comparisons between the two apps. For now it seems a matter of oppinion, however, strangely enough Lightroom seems to be the more intuative app.
Both of these applications will retail for $300 (Lightroom is $200 until the end of April). If that's a bit rich for your blood, there are other photo management and editing programs for the casual shutterbug. Adobe Photoshop Elements for Windows and Mac, ACDSee Pro and the free Picasa from Google (which is good and couldn't be cheaper) just to name a few. Speaking of free it's getting more and more difficult for these companies to make worthwhile commercial products that can compete with the built in tools like Windows Photo Gallery and iPhoto.
