I see the shadow photos you sent, thanks for the insights, but here are the problems:
1) first shot is on a HUMP OF LAND- not flat terrain. if the terrain is not flat, the shadows will not be identicle.
2) The shots of pencils/sticks- they are too close together, and they are not equal in Trajectory, one leans one direction, the other leans another direction, they produce different shadows.

The problem with the moon shot is that the groups of rocks producing shadow are all on an even flat terrain, the ground is leve, and in addition the groups of rocks are VERY similar in size, and they are far apart, their shadows should be the same, ir at least indistinguishable to us that there is a differrence.

Exactly

Exactly. But you only know that because I showed you the two other pics. Had I only shown the first pic, you would not have known that the pencils are leaning. The two other pics gives you a 3D vision of the pencils.

So what is my point ? Well, my point is this: When you view a certain pic from the Moon, then its like having a puzzle without ALL the pieces. You are using a 2D pic trying to determine how the shadows are falling in a 3D world.

The problem with the moon shot is that the groups of rocks producing shadow are all on an even flat terrain, the ground is leve, and in addition the groups of rocks are VERY similar in size, and they are far apart, their shadows should be the same, ir at least indistinguishable to us that there is a differrence.

How do you know that the ground is exactly level ? There are very few distinct features on the lunar surface and you have a 2D image showing a 3D world. So ... How do you know that the ground is exactly level ? The strong light from The Sun could have - in lack of a better word - "blurred" minor craters, hills etc., so that we only are seeing the shadows clearly.

THAT actually made some sense. you're right, I am remembering a single picture, from a certain angle. But what about the mountain issue I mentioned origionally? And what about x-box??

Lets move the mountain thing over to this thread: :D
