[QUOTE="Bob Blaylock, post: 493736, member: 16749"] Nearly all of my early learning was on completely-manual cameras, which left it completely to me to decide where to focus, and how to set the exposure. I've been somewhat amazed by the apparent intelligence with which my D3200 can now do all that automatically; but ultimately, the one thing it cannot do is read my mind and know for certain what I intend when I take a picture. It makes very good guesses, that are usually correct, but some times, I just have to take over, and control it manually. The wide-area AF mode is an example, of course, of a mode where the camera looks at all the stuff in the scene and tries to decide which item on which you mean to focus. Sometimes, it gets it right, and sometimes, it does not. As you've found, single-point focus gives you more control over the chosen focus point. Some times, even that's not enough, and you just have to go to manual focus (not easy, alas, if you have the stock focus screen in your D3100, which, if it is like the one that case in my D3200, was pretty much useless for manual focusing).
