Off topic but it's something that has always bugged me about so many of NASA's images of the lunar surface. The lighting is so often from the bottom right of the image making them look like bumps instead of craters. For example this looks like it's covered in pimples to me rather than small craters: https://phys.org/news/2016-10-reveals-lunar-surface-features-younger.html I always assumed it was because I spent so much time on computers, where all the user-interface buttons are lit from the top-left. When you click a button to make it look like it's being pushed in, the border colours around the button change to make it look the same as if it was lit from the bottom-right instead (plus the text is moved a few pixels to add to the 3D effect). I wonder - does that mean everyone who is used to south-east lighting sees UI buttons as being pushed in by default, and they pop out when you click on them?
