<br />it's just a darn shame that there were extra-bright dust storms happening in the same camera sweep as Nefertiti both times the area was photographed, thus eliminating the details inthe area we were all hoping to see.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">I'm not seeing any evidence of degradation. The images have superb detail when the contrast and brightness are adjusted to the range of the human eye. -|Tom|-

Oh my. You are absolutely right, Tom. I didn't know the data was there. This means there are lots more strips to look at. I just have to download them into photoshop first.

<br />The first step in examination of any image or image extract is to adjust the brightness and contrast for the whole image into the range that the human eye is most comfortable with. That is necessary to make the image look the way we would see it if we were there. Without that step, the image contains a great deal of information that our eyes cannot see because the brightness or darkness is out of our visual range.

Tom, I'm sure you're going to be very busy for a few days, but if you're saying you can "adjust" R0701791 to make the scene look like or comparaible to the contrast and brightness of the original M03 or E05 scene around the Profile Image, we'd appreciate if you would do that and post it. That way we know we're talking "apples to apples". I would gladly stand corrected, and learn from the experience. Please take R07 and make it look like M03 or E05 (roughly).

Thanks in advance.

Maybe if you post it right after this one (M0305549), we can see the differences and similarities:

Here's a cropping from R0701791 with nothing done to it, except cropping from the original MSSS strip R0701791.gif. This will make it easier to do the comparison. Please just save this to your harddrive, and adjust it to show the same kind of detail as above in the M0305549 image.

But R07 can never look like M03 because it was taken at an order of magnitude less resolution (12m/pixel) than MGS is capable of. That is getting close to Mars Odyssey resolution. You can't get face details out of such a low resolution image even if magnified and contrast-stretched. See for yourself. -|Tom|-

<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">So the question becomes: Why is the resolution so low?

BTW, the contrast and brightness variation I used in my original post on these strips (copied here) showed that the image could in fact be brought out (see upper right two slides), and was at least as detailed as yours, but more importantly, it also confirmed JP's opinion that:

"Be advised the Profile doesn't really stand out as well in these as compared to M03 and E05."

As you will note from our post above and from the MSSS website data summary accompanying each image, that the other Public Request image containing part of the Profile Image, but offset somewhat to the left is R1201454. The scaled pixel width on that image (call it R12) is 5.97, which is practically the same as M0305549, which is 5.65.

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.
