Mother Camel and Baby, Sahara, Chad, 1999

Photo: Camels drinking

A young dromedary camel peeks underneath its mother as she casually drinks in the Guelta Archeï, a steep canyon in the Chadian Sahara. But camels beware. These isolated waters hold a zoological surprise: Algae, fertilized by camel droppings, are eaten by fish that are preyed upon by a group of crocodiles.

(Text adapted from and photo shot on assignment for, but not published in, "Journey to the Heart of the Sahara," March 1999, National Geographic magazine)

Long Exposures

When making long exposures, use a remote release to avoid camera movement. If you don't have a remote release, use the camera's self-timer.
