Our driver, Rostom, had told us to be sure to look at our shadows while on the camels, but at that time I wasn't quite sure why. Then I saw this and understood what he was talking about. In fact, our camel driver later stopped the camels so we could take a picture like this and was waving his arms in the air so he’d show up in the image, too. I actually captured this while we were on the move, so just the driver plodding along (in his bare feet!) and no arms in the air.
