I knew my f-stop was small enough for maximum DOF and I wanted the bark in focus. Actually, I used autofocus on the tree, then flipped into manual so it wouldn't refocus, then lifted the camera higher and took the shot. I also manual focused on the tree several times. Did both. My second to last photography teacher had a short cut for long distance shots -- focus 1/3 of the way into the scene for it to be in focus from that point on. This was close to that.
