I have used Elements & now use LR/PS. I would definately not buy Elements again as LR/PS is so much better. I was hoping that my wife could make do with Elements, but this seems unlikely unless she sticks with JPG.
Elements, in my mind, really is designed for, and marketed to, a much more... Casual user, shall we say. To my way of thinking, if you've decided to shoot RAW you've not only made the de facto decision to post-process, you've committed to doing so on a much deeper level than what you would do if you were post-processing a JPG image. This is because RAW files require so *much* processing, at least typically speaking. Almost without exception they're going to require adjustments to white balance, contrast, color (both hue and saturation) and sharpening. And while you can do all of that in Elements, it's a bit like rowing a boat with a soup ladle: It'll get you where you wanna go, eventually, but there are such better tools for the job you really have to ask yourself why you're not using one of those better tools. Then you start playing with Photoshop and you discover it's *not* hard to learn and that as a photographer you only need to learn a tiny little fraction of what Photoshop is capable of doing and the next thing you know you're doing exposure blending and HDR and using actions and looking at Wacom tablets... At which point you are, officially, "One of Us".
