If you draw a triangle look at the distance across the sides near the apex, tip, vs that far from the apex is significant. Far is a lot of distance vs the close up to the apex. Wow, just like the photo... a movement is not much close up, but far is a lot. Angle of movement is the same. This explains why distance is blurred and close does not show movement.
Cool! Didn't think of the angle thing for near/far.
