In spite of their size and bulk, elephants can be surprisingly quiet when moving past a campground at night. (You know that they were there by the deposits that you find outside your tent in the morning.) This photo was taken in Lower Zambezi National Park, Zambia, with a Nikon D600 and a Nikkor 80-400 mm VR lens at 230 mm. The exposure was f/9 and 1/500 sec (ISO 800).
