Hi-res Stereo Views of Cydonia Face -large images!

These are spectacular in 3-D and worth the effort. -|Tom|-

The ESA initially released their first anaglyphs in red/green format:
www.esa.int/esa-mmg/mmg.pl?b=b&type=I&mi...s&single=y&start=302

They dropped this fairly quickly and have gone to red/cyan. The
reason for this I would guess is two-fold, one because red/green is
not a popular filter combination (not many people would have the
glasses which are even harder to obtain in Europe) and because
red/green is not the clearest format with which to view such
detailed images. Clarity and contrast are key. When it comes to
anaglyphs, there are three filter combinations available: red/green,
red/blue, and red cyan. While any of these glasses can be used to
view any of the formats with some success, anaglyphs done in
red/cyan and viewed with red/cyan glasses offer by far the best
results. The difference is in maximum brightness, contrast, and
detail.

There are other things that ESA and NASA always do wrong when it
comes to anaglyph production (which greatly diminishes the viewing
experience), chief among them are improper left eye/right'eye
alignment and improper stereo window placement. To see how bad it
can get there are no better examples than the Mars Express/MOC image
of the face (several big problems with that one), and the extremely
bad recent MRO effort of Victoria Crater:

Here's what it should have looked like (4+ meg png):


BTW, MOC images and MRO images can be sucessfully combined for
pretty good anaglyphs, the MOC providing the parallax and the MRO
the detail, as seen here in this image of some of the ancient delta
meanders north of Holden Crater:


Thanks for responding and providing a link for others, hopefully
they'll appreciate seeing the Face on Mars as if they were actually
there!

We're a bit unlucky as the illimination angles don't match as well I would like but on the plus side we get a little more detail and the anaglyph can be viewed with the face oriented closer to the way we're used to seeing it."

I still think the 3D views provide much more einformation than any 2D view, whatever the lighting or resolution. -|Tom|-

This is a mixed bag, some are HiRise/HiRise anaglyphs, some are HiRise/MOC, there are even a couple of CTX/MOC. Three or four were released as anaglyphs by the HiRise team but have been re-worked for red/cyan and better detail. Here's the link:

These are fascinating images. My first impression is that they strengthen the artificiality hypothesis, and at the same time weaken the idea advanced by some that the face was bifurcated - humanoid on one side, feline or whatever on the other. The simplest explaination seems to be that if the face is artificial, it was originally a symmetrical humanoid face, which has been heavily damaged on its left side by some process.
