National Geographic photographers have captured some of the world's most iconic images. For over a century, they've focused their lenses on stunning landscapes, vibrant communities and fascinating individuals.
Now, as the magazine celebrates a special anniversary, it has teamed up with art book publisher
Taschen to release a limited-edition collection of photographs: Around the World in 125 Years
Guest host Gill Deacon speaks with collection editor Reuel Golden
about how they narrowed millions of photographs down to feature 1000, how the view changed when National Geographic started addressing poverty and politics, and which "NatGeo" photo he considers the best taken since 1888.
