That was what makes the domes on Mars photo so obviously fake. But any 
photographer will check that because it's one of the things he looks at and 
checks before taking a photo. It just becomes second nature to look at the 
angle of the light source. Check out any good portrait and see where the 
light source is and you will see how much attention a photographer pays to 
.
