Hundreds of people attended the funeral Saturday.
Rob Stewart disappeared earlier this week while diving off the coast of Florida.
Various social media posts and an online fundraiser identify Rob Stewart as the filmmaker known for producing the 2006 documentary "Sharkwater.''
Rob Stewart's whole life changed the day he found the "curtain of death." In 1999, Stewart was 22 and enjoying a carefree existence as an underwater photographer and filmmaker. "I was selfish before. I was just travelling, photographing animals, thinking I had the best job in the world," he told us.
