Ye built in feature for many cameras but technically possible with a single shot if the arch is correctly aligned to the correct cardinal direction and some tinkering with exposure of the either moon or arch in Lr or Ps
If you think of it like this, the moon is going to stay the same size no matter how far you walk but the arch is going to shrink if you do. So you have a telephoto lens and take a photo really far from the arch so the moon will look bigger.
to hammer it home, put your thumb over the moon with an outstretched arm. completely covers the moon. now move your arm in a foot or 2 and it gets DRASTICALLY bigger. if you walk the same distance, the moon stays the same size
The moon is very far away. Its size will never change no matter where you are on earth. In relative terms the arch is very close compared to the moon. If you are close to the arch it looks massive, the further you move away from the arch the smaller it gets. It's pretty much the same as any picture you find when you Google "forced perspective photography". In this example the arch/people are the thing that are close to the camera and the moon very far away. To have the same effect, the photographer will have to move away from the arch until it's size matches the moon. (This ofcourse contradicts with the picture but as i said it is porbably cropped in. The perspecive of the arch will change dramatically whilest the moon won't change at all) This is also why I mentioned he would need a telephoto lens because you'd be pretty far away for the arch to get it to the same size. The photographer probably even cropped the image to make everything look even larger than it already is because modern lenses can't even zoom in this much to get the same framing. The original probably has a lot wider field of view.
That is a great explanation, thank you! Man, it must have been quite the cool puzzle to get this shot exactly right. Thanks to you I appreciate the photo even more!
