BRITTMAN, Its not so much that there is more of a site picture than it is a complete difference in your eye'e PERCEPTION of range.
We would do an exercise in a certain shooting school and they went like this.
Take your hunting buddy along with you to a spot that is elevated over say....a little wooded draw. I say wooded, because not only do we generally set up in wooded areas, but the extra "clutter" of the trees will throw your eye off even more.
Forgot to mention----bring along a decent rangefinder.
Pick a random object down there and make a good honest guess about the range, now let your buddy shoot it with the rangefinder. In most cases, you will judge it to be further away than it actually is.(particularly at the 45 degree range)
Exercise was used for teaching perception to the shooter----You won't be blessed with a spotter all the time. Works like a charm.
Just keep doing it till you can accurately guesstimate the range and can hit it with your shot right away.
I'm not disagreeing about form, I am just putting some more info out there.
