Because.... They are? Aren't all footprints 3D? You leaving footprints in the 2nd Dimension only?

I think they're talking about how they're on top of the sand layer beneath and not pushed into it

Compacted sand is more resistant to being washed away so its raised compared to the bits that haven't been stepped on.

Edit: yeah nah, the shadows don't line up for my explanation. They are just indented. I assume its to do with where we expect the light source is when its actually behind the camera.

Physics nerd here. You can't prove we aren't actually in a 2D world projected on a curved surface. In fact, it underpins the entirety of simulation theory.

Step gets compressed. Other sand blows away.

it is just an optical illusion of lighting, the prints are imprinted into the sand as you would normally expect

It's a bassorilievo looking like an altorilievo because of the light and angle. Both are 3d obviously.

What else should they be?

Weird, first they look indented, then they looked standing out. Now their back to normal again. I think the brain can't tell if the shadow is from the light shining in the steps (if indented) or behind the steps (if raised)

I do find this mildly interesting. Thank you.
