Filmmaker and photographer Dr. Jose Salgado has a unique perspective on the stars that line the sky-he’s also an astronomer at the Adler Planetarium. His most recent work is an up close portrait of the Northern Lights. And, now the Lights will be more than just a visual experience. Dr. Salgado has teamed up with the Grant Park Orchestra to bring a live score to the astronomical experience. Dr. Jose Salgado joins us to explain how you shoot-then score-the stars.
