I was listening to Camera Dojo's podcast this morning and they were talking about editing Raw. The guy said he can adjust 2 full F-stops in Raw. 1st question, F-stop has to do with Aperture, right? If so, I thought the benefit to Raw was going +1 or -1 in EXPOSURE. 2nd question, when I import all my files into Lightroom (I shoot Raw+JPEG) does Lightroom automatically work on the raw file? In my case it is .CR2? 3rd question, once it's in lightroom and I notice that the picture is too dark/under exposed, is it just a matter of changing the Exposure to +1, assuming I'm working on the Raw file? 4th question, is that even the right way to think of Raw? That I can simply go in later and change the exposure as though I would had I changed it before I took the picture on the camera? Thanks!
