Lunar Two Towers

[Sgt.Rocknroll]

I've got a problem. While looking at my archive of previous work I wanted to re-visit an old video from Lunar Orbiter 5. I found I had more than one photo with basically the same name but from different websites. They're basically the same area, with one a little closer to the surface  and one covering a larger area.  The first is from ASU (on the left in the side by side photo) and the second (on the right) is from LPI.USRA.
This is a side by side comparison with the tower in the center of both. Neither photo has been altered.








Need some input here. I know, I know the one with the better resolution should be the one, but they're both good and I don't have time to do both.

Tell me what you guys think. (this should be fun)

I suggest you use the one with more shades of grey, theoretically it shows more detail.

That would be the one from the LPI, it has 238 shades of grey while the other has 233. Not much difference, but may be enough.

[Sgt.Rocknroll]

Thanks ArMap , I was leaning towards that one too.

Wow I see what looks like a fallen billboard and some steps of some kind. I see it after enlarging the second image almost in the middle of the far right. The sign looks like a 2 post square sign knocked on its back. It even seems to have another rectangle at the top if it.

Something like this below.

I would go with the darker image Sarge.

Were those two pics taken at the same time?  The shadowing looks identical.  Maybe the same time of "day?"

[Sgt.Rocknroll]

Not real sure about the time. I have info on one but not the other. Need to do some research.

[Amaterasu]

Just thought it odd that two photos from what sounds to Me to be two different sources (did I get that right?) would have such astounding correlation of shadows.

[ArMaP]

I think that they are just two different digital versions of the same photos taken by Lunar Orbiter.

[Elvis Hendrix]

Yes They are one and the same lunar orbiter photo.
Have at it sarge
This collection in my opinon  show definatave evidence of past or present civilisation on our moon.

Without doubt.

cant wait to see what sarge comes up with.

They look more like consecutive photos.  There is a slight shift from one to the next.

A shift in what?

The image from ASU is one quarter of the full image, the top right corner, to be exact.

The four images from ASU, each in one colour.


The four images from ASU compared with the image from the LPI. Same image, just a slight distortion between the two versions.

[Amaterasu]

Ok, ArMaP.  *I* see what looks like a slight shift in overhead position, giving that "distortion." If the two photos were taken relatively close together (depending on speed of craft) of the same terrain, You could easily "match it up" and call it a "distorted version of the same photo."

If they were two photos taken from slightly different positions then the animation I just posted would gives a 3D view of the scene, which is not the case.

The Lunar Orbiter photos were taken 4 at a time, with a larger photo occupying most of the frame and 3 smaller , higher resolution, photos at the right, as seen here.

[Amaterasu]

Ok, ArMaP.  You're right.  [smile]
