What's going on here?

It's because the light is coming from the bottom right. Most graphics
and images show the light coming in from the top left and your brain
gets used to that and tries to make sense of images in which this is
not the case (like mine here) by reinterpreting the craters as domes.

Ah.... right. I just copied your photo and rotated it through 180 degrees,
and lo and behold, the craters have become properly concave. Thank you! This
has been an ongoing puzzle for me for a while with lunar photos.

(I'm now off to do some experiments, photographing everyday objects with the
light coming from the bottom right...)
