Lightroom came from wanting to firstly read the RAW file and then apply overall, parameteric changes to the picture. It is probably a king in being able to draw non proprietary information out of RAW and along the way, tweak the look BEFORE handing over to PS.


It is parameter based not so much pixel by pixel based. The plus has now been enriched with more and more features inclusive of cataloguing. It is not expensive and the Ultimate package comes with some goodies. If you don't want a fat product or an onerous payment per PC (legally), use a competitor like Corel Paintshop Pro - which has a different culture and way of working, in some sense, tutored and simple - but with less engineering refinement. LR can record a "look" based on the parameters and batch apply it to a whole bunch of other photos. PS CS5 can but the price is quite a bit more. PS Elements I think lacks macro recording so you can't record a script and play back the effect on another photo. It allows you to layer and mask the picture like a real painter with a real canvas and real paint could do. It has a huge list of tools and subsequently effects that allow you to adjust the whole picture, specific regions or single dots (I think). It deals with photos at a dot by dot level. You can make an art piece using PS from zero. You do not have to begin the art piece with a photo. PS came from photography but also from the art world. It has very many tools, and the skillset you pick up with that interface brings you to a professional level that can be used to make money or seek employment as a photo manipulator or a graphic artist.

PS is a very rich bitmap and photo editor - it can get at the RAW data if that is what you want by depending on an intermediate module like ACR or LR.
