[geocentrism] Re: Comet Wild 2 photos

Hi Paul,
I thought of that but initially I see it as concave then suddenly it reverses. I suppose I could copy the photos and turn them upside-down but not changing left to right! I'll try it standing on my head and see what happens!

I think this may be due to an effect I alluded to long ago in reference to the JAXA photos of the Moon. It's all to do with where your brain tells you the light is coming from. If you rotate the image in 90 deg increments, I predict that one of them will exhibit a convex appearance. If you do the same to a vista of Luna craters, one of the positions will probably appear as convex even though you know it's concave.
