18. John Shearer

Location: Los Angeles, CA

John Shearer is a founder and photographer at Invision by the Associated Press, and whether you know it or not, he's taken some of the most widely seen music photos of all time. One of those images shows Madonna and Britney Spears kissing at the 2003 MTV VMAs, and others capture artists like Rihanna, Prince, and Gwen Stefani in their prime. His work is crisp and vibrant, making his subjects look the best they possibly can while performing their asses off on stage.
