<br />Therefore, if the supposition is correct that this is all a matter of variations in brightness and contrast, then R12 should be able to be adjusted to make the part of the Profile still included in it, appear as clearly defined as it does in M03.
But if our working hypothesis is correct, that the data is for some reason is absent from the image, then increasing brightness and contrast will have only a very limited effect. Can Tom or Rich or someone with good photo enhancing software please do that experiment and let us know which is the case.

I believe you have posted adjusted images of R07 two or three times, but not R12, (except in JP's "orientation slide" which is not adjusted). What I requested was to adjust brightness and contrast in R1201454, in a cropped image that will show at least a part of the girl.
If I am wrong, would you please refer me to page and date where you posted it?

I concluded very early that R12 had less to work with than R07, but had the same problems. Same contrast and brightness, but off the screen to the left.

That may be true but looking at it addresses Tom's point about resolution. We need to see it in the contrast and brightness adjusted version to know if the better resolution makes any difference

We already did, and we concluded it was worse. In other words, the contrast and brightness was the same as R07, but the image composition was worse. That's a red herring.

Apparently, the spacecraft managers were economizing on bits for this "public interest" phase.
