The soil underneath wasn't visibly disturbed because the engine to lift off and land was weak. 1/6th mavity and the fact that the LEM was very light meant it didn't need a lot of thrust to get off the ground. If you were expecting clouds of dust to billow up, you wouldn't see that because there's no atmosphere. Any dust kicked upwards would follow a perfectly parabolic arc back to the ground.
Regardless of atmosphere, some experts retain that there should still be some indication of dust disturbance from the thrusters.
No soil on the landing feet? That's a new one on me, but why would you expect dust on the landing feet?
This dust would be kicked out onto the landing feet.
No stars: the photos had their exposure set for broad daylight because they were on the daylight side of the moon. The glare from the moon's high-albedo surface would have washed out the comparatively dim stars.
I don't disagree that this could be the case, but some photographers debate this.
Multiple light sources: no. Just no. This one has been covered so many times, but there was only one light source.
Well, actually yes.
I think to say conclusively either way, is foolish. That's my opinion.
