Stop my head from spinning, what is needed and not needed in photo editing software? I've never edited, though I've poked around CS5(trial), Lightroom(trial). I understand the difference and what either is used for. But I don't know what I need. I've basically always shot jpeg and want to switch to raw. I've read quite a bit and there seems to be a variety of opinions that point all over the place, Aperture Gimp, Paint.net. Please help, thoughts, opinions, advice. I've never edited and don't know the extent of what I need.
