Hi All, I'm a total noob who is trying to learn all I can before my first SLR arrives in a week or so (the waiting is killing me). I was reading the tutorials and have a question after reading Tiberius47's peice on the different shooting modes. In AE the camera picks the sweet spot for a picture, setting-wise. The tutorial states that you can adjust up and down the scale from there - raise aperature/lower speed/etc or the opposite. All while the camera is adjusting everything to get the best shot at the new settings. In Aperature Priority you pick the ap setting and the camera does the rest. My question is: how are these fundamentally different. Shouldn't I be able to do the same thing in both setting? For example if I want an ap setting of 8 - i could roll through the setting combinations in AE untill i got to the one at f8, or I could got to A and dial straight to f8. Since the camera adjusts all other settings shouldn't I arrive at the same place using either approach, or is there something else that happens that I'm not catching? Thanks for the help!
