I am looking for a RAW format image processing and editing tool that has a little more than the standard import and initial processing [i.e., white balance and exposure editing] than what is standard with photoshop 7, in terms of workflow and management. I have been reading up on Adobe photoshop lightroom, but I'm confused about what it is. Is it a plug-in, or a seperate editor that just imports to photoshop? I need some sort of RAW processing and editing above what photoshop 7 already does, but do I need a program like lightroom? Cost is somewhat of an issue for me as I just can't do $700+ to upgrade to CS2 or CS3 from photoshop 7 (which I've had for a while, but not really learned fully). Does photoshop 7 have the kind of RAW functionality I need, built in? Or should I go with lightroom (or some other moderately priced program of the like), if I want to exclusively work with RAW?
I'd appreciate any feedback.
Thanks.
