Hi,
Silly question, but I know craters are concave and it takes a while for the brain to transform it from convex to concave, but these craters look convex to me no matter how I look at them.
Is it me or are they really convex, like plateau's?
edit : ok finally got it by staring at the small crater around 9 O'clock and then all of them appear concave, but it reverts back quickly. must be the age catching up!!
