*  Too bad the astronauts didn't know about
* "weight shift" 3D; we could have had some nice stereo pix of Armstong posing
* next to the LEM.

<<But they apparently did. From the same transcript Bob found
(http://ees.lanl.gov/APOLLO/a12.clsout1.html):>>

118:07:57 Conrad: Yeah. Yeah. Yeah. Yeah. (Pause) Want to get a picture
of that?

118:08:03 Bean: Sure do. Let me get it set up. (Pause) Right. (Pause)
5(foot focus) at f:8. (Pause)

     [Bean - "We had a set procedure for taking these samples. And
     usually Pete would point to the rock, put the gnomon near
     it. Sometimes I'd wonder which rock it was, you know, if there was
     a bunch.  And, then, I would take a photo and then step a pace or
     two and take another to get a stereo (pair) and then Pete would
     pick it up. And, meanwhile, I think I'd get out my little sample
     bag and he'd put it in the sample bag. And then we'd stick it in my
     (saddle)bag or his bag. So we had like a little skit and that's
     what I think Pete's talking about now."]

<<and later>>

118:18:41 Conrad: Just a minute. Okay. Now, let me go over here, and
I'll give them a stereo of this baby.

118:18:46 Bean: Okay. 

     [Pete is going to take a second pan and steps to his left to get a
     stereo effect. This second pan includes AS12-46-6845 to 6852. Note
     in 6846 the increased separation of their shadows.]

It's nice that they're indexing this transcript with picture numbers
that can potentially be fed back into altavista, some have links already
set up.

They do say that taking the stereo pictures was kind of a mistake,
because it took time away from rock collecting. They had to take
pictures without benefit of a viewfinder. They practiced taking pictures
that way, of things from different angles and distances, on earth.
