I am new to photography and I'm trying to learn how to use my own settings instead of the pre-set buttons on my Nikon D3000. I am going crazy in the process. No ONE manner of explanation does the trick for me. It takes me reading a bazillion different websites and watching lots of videos to pick up little pieces here and there. The hardest part for me seems to be memorizing how the values affect the photos (numbers going up sometimes do the opposite of what my brain wants to think they will do, ie with the light). Also, while I think I have conquered ISO (keep that one lowest unless absolutely necessary to get more light?), I have no idea how to use the aperture/speed combinations, and the biggest thing I don't get, is how these are affected by my 3 lenses. Mainly the 55-200 and 70-300. If anyone has a tidbit of knowledge to toss in, please do. Every little bit helps, and I never know when that dawning moment will finally hit me. The more simplified, the better, it seems!
