Textured Reasoning
image by " rel="nofollow Thilo Schramm, Kiel, Germany
Here is an image that is very different than any we have seen. It is a full Moon view but
haves a strong 3-D effect. All Thilo did was "shift the blue channel some pixels." So this
image is not revealing topography, but still reveals interesting features. Two things are
most notable. First, rays show up like mare ridges because the displaced blue pixels look
like shadows of the brighter red and green ones. Thus, the rays from Copernicus appear
as radiating ridges. Older and fainter ridges must have less blue for they simply look like
faint rays - see north-eastern Imbrium. The second notable feature is the ruggedness of
some maria, especially Tranquillitatis. The offset of the blue pixels would have maximum
3-D effect for lunar materials that reflect more strongly in the blue - that would be titanium.
Comparison with a compositional " rel="nofollow map shows a nearly perfect match of titanium and
rough texture on the Thilo image. In fact, perhaps the reason rays don't appear as ridges
in north east Imbrium is that the lavas there are titanium-poor. This would make sense
because the small projectiles that make rays excavate the material where they hit.
