Nope, if the picture were taken (with a color camera, of course) when the
observing site was in daylight the background would also be blue.  Daylight
imagery of sun-lit satellites is entirely possible -- Ron D. has done it
with a B&W camera, and the picture
was taken in daylight and was originally in color -- I have a copy of the
videotape it was taken from and a description of the Sony CCD camera used.
Believe me for the moment, the background is quite blue and looks
qualitatively similar to the Shenzhou picture being discussed.

None of this is to say that I'm going to defend the "it's a real
ground-based picture" theme to the death -- but it still looks more like
that to me than the other, clearly simulation-generated pictures on Mark's
