I've been, stupidly, using iPhoto ever since I got my iMac in late 2009. I say stupidly, because I never really knew anything about which formats to save as, how to store my files, etc. iPhoto only would let me export jpegs, while the whole time I was shooting RAW on my camera and importing it as nothing more than a jpeg- what a joke, on my part! Silly me. Well, I've learned what's 'right' now, just this past week, and I'm looking to do a complete system revamp. Went and put all 800 gigs of photos onto a quality external yesterday and now am looking to upgrade to a better photo management program that'll let me tweak more and actually use the files as they meant to be used. From what I've read, LR is great for this type of thing. I just want something that I can import all my photos to straight after a shoot that will archive them and I'll be able to do whatever I want with the files, in whichever way I want. Is LR what I need? Also, how does it work with LR4 do I just use it as beta now and just buy it when it becomes fully 'ready'?
