I'll post this photo of mine as an example. When you're shooting something going away from you that starts up close (a fence, a trail of foot prints, etc) where is the "ideal" focus point? I seem to recall that if you're shooting a landscape for instance that the ideal point to focus on is the point 2/3 of the way to the top of your frame. Does that hold true for everything or is it simply "play it by ear" and go from there? In the case of the photo posted, the focus point is on the far fence post as opposed to up close.
