As part of the continuing celebration of its 125th anniversary, National Geographic once again features Steve McCurry's famous 'Afghan Girl' photograph on the cover of October's 'The Photography Issue'. Along with the new issue, National Geographic has launched some supporting content associated with the issue, as well as a new blog called Proof, offering 'new avenues for our audience to get a behind-the-scenes look at the National Geographic storytelling process.' 

The cover of the October 2013 issue shows a cropped version of Steve McCurry's famous photograph of a young Afghan girl, Sharbat Gula, which first ran in the June 1985 issue.

Though launched in 1888 as an extension of the National Geographic Society, National Geographic Magazine wasn't initially known for its photography. Starting in 1905, the magazine started adding more photographs, which became a critical part of their storytelling style.

The just-launched blog Proof features interesting studies of ongoing and past projects from photographers and journalists, some of which may not appear in publication, but are interesting in their own right. The goal, according to Keith Jenkins, Director of Photography, being 'to tell meaningful stories in unforgettable ways.'

'The Photography Issue' of National Geographic can be found on newstands now, and a digital version is also available.
