Cartographers have always known that the direction of light on a topographical object affects how we see it, whether it is seen as a mountain or a hole in the ground.
Here is a wonderful example of this. These are goose footprints as I photographed them on the Lake Ontario shore the other day.
And here is what they look like turned 180°. Pretty cool, eh?
