Ok, I've heard that most people use a program first (like Lightroom) to do some adjustments in RAW before importing their pics to Photoshop. Is THAT correct?? And if so, why?? Does Photoshop not have the basic adjustments like WB or exposure?? Do you NEED another program to make these adjustments? I just recently bought CS4 (and a book to help learn). I'm making the switch over from Aperture. I've never used Lightroom before (and I currently don't own it) but I'm wondering if it is similar to Aperture. I would like to not have to purchase Lightroom right now if you don't think it is necessary. I am willing to invest in it if there is NO comparison to the two programs. Also, could somebody please explain Camera Raw and if this is essentially the same thing?? And, if so, why are people using Lightroom too? Thanks for your help!
