Ball, your sarcasm just proved my point. Obviously depth (or, distance) changes the size and relation to everything in the picture. This is what nobody has pointed out, and what I have tried to show you.
1 - You KNOW the height of a man
2 - you KNOW the rough height of a tree, or can guess.
3 - you KNOW that things further away look smaller.
so, using your existing references, you can TELL that in that photo, the person is a HELL of a long way away from the trees, and they are way the freaking hell out there.
Using the SAME system you can try to figure out how far the b24s are from the ground in some of the photos above. Only, with the bombers, you don't always have the spot of ground (the point you are measuring to, directly below the bombers) in the photo, so you can estimate but not be sure. In the top-down angle on the smokestack photo you have a much easier time of it.
A lot of folks see a bomber a fraction of an inch over trees and think "my god that's low!" but don't stop to look at the photo and realize the trees are way the frak off in the distance which means they're much further away. That type of deal.
It's like a logic lesson. Folks can reason for themselves, but sometimes when you point out the process they think "ooooh, I know that" -- they just didn't use the knowledge until it was pointed out.
