So I'm kinda not getting the small apature thing. I understand the large ones - it's easy to see. I was doing some reading and read that most landscape pictures are taken with f11/16.... why not 22? The smaller the apature the more dof you have right? So if you're shooting a landscape why wouldn't you pick 22 over 16? I think the point shows when people take those stupid pictures of apples when showing DOF tutorials. Setting this noob straight would be a great help.
