Isn't it? I was pleased with this.

You are right, of course, I was taking severe artistic license in this matter!
Of course the glare would make the shadow squares all but invisible - however,
it is likely that they would be partly visible during twighlight, and probably
very obvious at night, when they also occlude parts of the arch. I think the
nature of their world would be more apparent to the natives than Niven thinks...

Yes, this was an attempt to depict glare. What I really need to do is make the
glare larger, the sun's disc smaller, and use some kind of colour bleeding to
produce a more (photo)realistic effect. I think it is time to investigate Sam's
macros... :)

I have seen variable-exposure hdr panoramas on photography sites - perhaps I
should also investigate this... I expect the tools required are expensive :(
