Adobe Photoshop Lightroom 2 is best categorized as a Digital Processor. That is, from bringing images to your computer, cataloging them for later retrieval (and, if you want, backing them up to insure protection against accidental loss), enhancing and fine tuning your images, all the way to printing and/or digital distribution—one can do it all from Lightroom. However, one of the strongest reasons to use Lightroom is the opportunity for playing with images with no concern about how many versions and variations of the image you create without screwing up your original image. Any alteration you make on an image in Lightroom is only how Lightroom lets you "see" the image. Nothing is changed in the image itself unless you save a copy with those changes. The biggest negative about Lightroom is that the interface constantly changes, depending upon what you've clicked. This makes "hacking" the program a challenge, and working with Lightroom isn't helped by the manual that doesn't properly explain the conditions where you will see what is being explained. Despite the complex learning curve, there is much to like in Lightroom.
