It does of course.  Any elevation above ground from your standing height (or
lower?) to orbital height (and higher?) can show it.  Look into your own heads
shadow at noon and you'll likely see it's brighter immediately around the shadow
edges, from an airplane shows it very well, and there are numerous Earth photos
which show it too.  This particular image with the sunlight direction off-center
may be a different story though.  Anyway I've never seen that much before, it
implies a lot of roughness, or *small-scale angular faceting, on the surface.  I
want to try that type of highlighting myself now  :-)

*blinn microfacets?
