Check out National Geographic’s collection of brilliant photos submitted by photographers all around the world, each with their own unique description. Like this one, aptly named “My Camp”, taken by Tommy Eliassen;
An orionid meteor streaking over the sky, the aurora borealis in the northern horizon and the milky way over my camp at Korgfjellet, Hemnes, Norway on October 20, 2012.
There are three categories listed (Nature, People & Places) with 11 weeks each, with about 8-10 photos per week, so theres a decent collection of quality photos! Downloads available are for your desktop, ipad and mobile.
