Hills or Craters?

This is a nice picture that was posted by Graeme Hill on the Off Topic Diccussions forum "Posting an image" string.

When I look at this picture, I get the same effect I sometimes have looking at the moon at very high magnification through a scope. The topology looks inverted so the craters look like hills. By looking carefully at the small crater on the left, I am able to flip things in my mind so everything looks normal.

I've never seen this effect in a picture before. Does anyone else see the same thing?

Yes. If I look at long enough, they do look like hills! Look away for a bit then they look like craters again.
