(confused )which ones are camels and which ones are shadows?

The National Geographic Magazine took this camels in the desert planform photo by 2005.

There is a wonder top view photo of the tail wagging the dog. In the matter of fact, the black ones are shadows and the white ones are camels. When sun rises to a certain height, the object shadow become proper proportion as the reality .Obviously, light can be art, shadow can be illusion.
