I consider this my entry into the View Camera world
The most effective technique involves viewing and focussing from the side, rather than the top.
Ideally, you'll have the camera on a tripod that raises the camera up to near eye-level. Alternatively, nearby trees, posts or walls can help.
The lens points toward the subject, the base of the camera and the finder each point sideways, and you stand to the finder's side and look horizontally into the finder.
The image is, of course, upside down.
Any time I've tried to do this without a tripod or suitable vertical surface:
1) the results have usually been poorly framed, improperly focussed or blurred by camera movement (or all 3); and
2) I've felt a compulsion to start quoting from Shakespeare (Hamlet: "
Alas, poor Yorick! I knew him, Horatio: a fellow
of infinite jest, of most excellent fancy").
