Not to mention that they only had one camera, which was in Armstrong's possession most of the time.

Yes, but that's more an effect than a cause. They indeed had only one EVA camera, but it was assigned to Armstrong for most of the mission because they knew he'd take the best photos. There was another Hasselblad in the LM, but it was the orbital model -- black body and no reseau plate. Roll 37, which has just been added to the ALSJ, was taken from inside the LM with this camera, mostly Aldrin's photography. (He really wasn't that bad, but Armstrong had displayed better intuition and was already experienced in photography.)

Not arguing with you, but when was this? (I don't remember seeing it.)

It's pretty hard to see. I've got stills on my web site http://www.clavius.org/gravleap.html

I didn't look for it until I read Armstrong's debriefing where he says he jumped as far up the LM ladder as he could get. Once you know what to look for in the EVA footage, you can see it.

On Apollo 15 (the first TV of a LM takeoff), he didn't try to anticipate, and the LM soars out of sight almost immediately.

And on Apollo 16 he tried to anticipate, but got the timing a bit wrong. (The tilt and zoom rates were constant.) And on Apollo 17 he got it right, allowing us to follow the LM ascent through several seconds past pitchover.

And incidentally, after pitchover you are looking right up the LM's engine bell and you can see the glow of the engine. It's a little bright dot.

[n]I think it was more that the administration (Kennedy/Johnson) that had appointed Webb was leaving office, and Webb was planning to leave with them.[/b]

That's just as plausibe a reason, especially since the administration was switching from Democrat to Republican.

Webb was responsible for having secured the vast amounts of funding that propelled Apollo through the mid-1960s, and he did so via less than happy means. Historians believe Webb used tactics similar to J. Edgar Hoover (i.e., knowing in whose closets all the Congressional skeletons were hidden) to essentially blackmail Congress into giving him the money. Regardless of how well he'd done his job, I don't think the Nixon administration would have allowed him to retain his post.
