This is easily the best photo editing software out there today for a number of reasons. Yes, it is a bit expensive, but the fact is that any pro or amateur who wants to get the most out of his or her photos will find everything they need in Adobe Lightroom. I have used a lot of the features regularly with my photographs, but there are still dozens of main features that I haven't even tired yet, which should tell you how awesome this product really is.
Ease of use has to be my favorite thing about Lightroom because I like to be able to edit my photos on the fly, which this allows me to do. I know plenty about cameras, but editing software was always tough for me to grasp until I started using Lightroom. Now I can edit my pictures exactly as I need to without having to watch tutorial after tutorial to figure it out.
One of the more underrated features of this software is its organizer, which allows users to quickly rename, export, or even edit individual or batch photos. It's one of those features that they could have left off, but anyone who has used it knows how much more value it adds to the product.
