Hi turbonium! Nice to hear from you again. Let's see if we can't give this one more try. Now might be a good time to grab some popcorn. This post is going to get a bit long.
Here's the collage I assembled from the video stills you posted back on
this thread.

We're looking at this portion of the LM as seen in
AS12-46-6728 (caution: link is to 1.2 MB image file). This shot is very similar to the full image MID posted earlier:

The only difference is that the video viewpoint is much closer to the LM, as Al Bean was in the process of removing the camera from the MESA platform at the time. The viewpoint would have been similar to this shot of an LM mockup (but even a bit closer still -- almost directly underneath the plume deflector):

Just look at the strut and plume deflector geometry. Compare the strut positions, the insulation pattern, and the color patterns on the actual Apollo 12 Hasselblad image to the video collage. Can you really not see that the video collage is showing the same object as the two above photos?
The problem is that you're comparing a high-resolution, color-corrected Hasselblad film photo with a low-resolution, highly-compressed Web video originally shot on a color-wheel video camera with less-than-stellar image quality. Take a look at these two images of the STS-26 launch, one from a
still camera and one from a
YouTube video:

Why is the external tank green in the second image? What happened to the orange? Nothing, of course. It's just lousy color balance and poor video quality. You're seeing the same thing on the Apollo 12 video. The gold Mylar is there; it just doesn't appear quite as gold as in the color-corrected Hasselblad photo. I have no trouble at all seeing it.
Hi Pericynthion
I've got my bowl of popcorn, and I'm ready to go!

First, as to the comparison between the high quality image(s) and the video still(s) being a problem - let's compare my video stills to several other Apollo video stills of the LM. You'll find that
all of the other stills
do show gold mylar.
From an Apollo 14 clip, at approx. 1:07...
http://www.hq.nasa.gov/alsj/a14/a14v.1150603Watch the entire clip linked above. The camera swings around (quite quickly at times), and the gold mylar is always seen on the LM as it comes into view several times. Watch any of the other Apollo 14 clips that include the LM - they also show the very bright gold color of the mylar, at all times.
And, if you have the time, watch the clips from Apollo 15, 16, and 17. I've looked through all of them, and every one that shows the LM gold mylar
has GOLD colored mylar. If you find any examples that can even compare to the
non-gold ones I've pointed out in the Apollo 12 clip, then please tell me where they are....because I can't find any, whatsoever.
However, if you
can't find any other non-gold mylar that has other colors present (ie:blue-green, white, flesh tones), then will you concede that your argument about it being caused by the "low-resolution, highly-compressed Web video originally shot on a color-wheel video camera with less-than-stellar image quality", is not valid?

Sorry, but the "test pattern" you see really is just color banding. It's a well-known, common artifact of that type of video camera.
No, color banding is nothing like what we see in the Apollo 12 clip. First, here are two examples where color banding
does occur, in the Apollo 14 clip I linked earlier....

And here is the still I posted from the Apollo 12 clip....

Compare the stills...
- the Apollo 14 color bands are randomly curved, and have no defined "border" around them.
- the Apollo 12 color bands are quite straight, and have a distinct, quite square, black border around them.
But this is the most important difference - watch the actual clips to compare how the Apollo 14 color banding quickly "flashes" in and out (app. at 1:07), while the Apollo 12 color bands do not. That is, as the camera moves downward, the bands
come into view. Watch the Apollo 12 clip from about 2:04 to 2:07.....
http://www.hq.nasa.gov/alsj/a12/a12v.1155619 They are two completely different things. The Apollo 12 color bands are actually concrete, present in the scene itself. They are
not the result of a camera glitch, like those in the Apollo 14 clip.
I'll address the rest of your post later....
Cheers
