Another photographer to check out is Steve McCurry, perhaps best known for the stunning portrait of an Afghan girl photo (right) taken in 1984 that appeared as a cover shot on National Geographic magazine in June 1985.

It is impossible to pick even a few favourites from the shots in his galleries – check them all out (clicking the photo takes you to the next in the series, and at the end of each gallery back to the index page, so it is very easy to go through all of them). When you’re done with the galleries, check out the journal pages, including the September 11, 2001 entry from New York.
