Well, while I'm on the topic of post processing photos in general, let's take a look at my wish list item #2: Adobe Lightroom 2. :P
Okay, so why Lightroom over Photoshop? To be honest, I have never played around with Lightroom in my life, but with Photoshop, it feels really overwhelming with the many things you can do, actually almost too many. I've never been the one to use Photoshop to its full potential with all the features it has. Typically I just use Levels, cropping, and other pretty basic edits. It's probably because I've never been the creative type when it comes to artsy stuff. :(
Anyways, back to why I want Lightroom, or at least try it out. Supposedly it's designed for photography as well as its easiness in using. Like I said before, I have yet to try it out, so I'm basing my opinion from reviews as well as hearing from photographers about using Lightroom over Photoshop.
