The R12 and R07 images match perfectly the effect of reducing the brightness and enhancing the contrast of the M03 image. I just did it myself in photoshop and obtained a near perfect match by setting the brightness to -70 and the contrast to +80. Try it yourself.
Another way of saying this is that the R12 and R07 images are only picking up the very brightest parts of the image (beyond a certain threshold). They are severely limited strips, therefore, since they leave out the vast majority of image data.
My questions are:
1. Where are the links to these strips online? (Or where were they obtained from?)
2. Are there other strips with a similar brightness/contrast problem?

emanuel,
If you look closely at what we said, you'll see that we never said that you couldn't make M03 match R12 and R07. One can always go in that direction.
Let me give you an analogy.
Imagine one person has an original Mona Lisa.
Then imagine another person with an artwork the same size and shape, materials, paint, era, frame, as the Mona Lisa, but all it is is a collection of dots. The owner of the artwork walks into a famous museum and says, "I'd like to sell my copy of the Mona Lisa for $2,000,000."
The curator looks at him, incredulously, and says, "that's not a Mona Lisa, that's nothing but a collection of spots." To which the owner replies, "oh no, it's exactly like the Mona Lisa, watch."
So he goes and gets the real Mona Lisa, splashes paint thinner on it, brushes it with a wire brush, sand blasts it, and after five such treatments, it's nothing more than a collection of dots. He takes his picture, stands it next to what's left of the Mona Lisa and says:
"See it's the same as the Mona Lisa."

This might be another way to confirm the existence of the Profile Image (artwork) with electronic data, at least in R07 (in R12 the Profile is offset too far to the left I think). Does it? and what does it look like?

MSSS website, Gallery, same coordinates as M0305549 (almost).

How do you search for coordinates on the MSSS website? I don't even know how to navigate to the original Nefertiti strips. I have been using the direct links in the original post above.

Hi Emanuel,
It's easy, go to the MSSS website (same website you used for the other Profile links), find Mars Global Surveyor/Mars Orbital Camera, find MOC Gallery, click on for the letter group you're looking for, find the Mars map grid with "quadrants" (bricks) in it, look for "Phoenicis Lacus." Click on and look around the coordinates listed above (108W 14S I think). It's fairly easy to find, and then you have a tool to find more stuff for your future searches.
Neil
p.s, If you can't find it I'll give you the links tonight.
