Documentary work is sometimes described as a blend of journalism and art. It's certainly a fitting description of photographer Sebastiao Salgado's work. The Brazilian artist has traveled the world taking hauntingly beautiful pictures of the world's poorest people, including those dislocated by need or war. This thoughtful piece explores Salgado's work in the context of a traveling exhibition.

There's nothing fancy here but the piece is done with care and quality. Jenny Brundin interviews Salgado, the exhibit director and several other observers of the photographer's work, and carries the piece with well-written narration. The piece makes sporadic and evocative use of background music.

A fine NPR-style arts feature that would enhance any magazine show.
