Andy, that's exactly what happened to me! Also, after looking at the animation posted by Lucky, then the craters on the moon looked like craters. I guess the brain is easily fooled by these images.

Thanks.

Thank you, Lucky. The link to the modeling site was helpful. Now when I look at the craters they do look like bowls. I think it''s my eyes!

Craters are an optical illusion?

Feb. 9's picture of the moon craters: To me the craters appear raised, not bowl-shaped. Is this an optical illusion?

This is the first time I've posted, but I have enjoyed this site for quite some time.
