Inspired by friends like Bianca Valenti and other hard charging female surfers, she began going out in the big waves of her backyard—the gnarly waters of Ocean Beach. Equipped with fins, her camera, incredible stamina and plenty of determination, Cunningham has made it her mission to capture what it looks like to push the ocean's limits.
