I mentioned a while back the opportunity to buy a Minolta 7000 SLR. Well, I took the plunge and got it along with a 50mm, a 28-70mm and a 70-210mm lens. I've started playing around with it... I'm in the process of working my way through a film right now. But this is all very new to me, having only used compacts previously. I've think I've sussed out what each of the lenses is capable of and I've worked out how each of the functions works on the camera but words like "exposure" scare me. I know what it means, I know what "shutter speed" and "aperture" and "depth of field" all mean, but it seems to me that you need to know what a hell of a lot of different numbers do and my eyes start to glaze over when I try to understand it all. When I'm taking a photograph, should I be looking at each of these things, or does it work on a case by case basis, using only one or some of them depending on the shot you're trying to take? And have I just confused each and every one of you because I'm started to get a little bit confused myself?! Any advice for this fish out of water?
