(FORTUNE Small Business) – If you want to take a photo class in another medium, the Jim Church School of Underwater Photography, based in Miami, is the only school that uses live-aboard boats from the Aggressor fleet, specially outfitted for underwater photography. (The boats include rinse tanks for cleaning equipment, as well as onboard computers and software for downloading, editing, and archiving photographs.) The school will even stock equipment and chemicals onboard for film photographers upon request.

Named for former Navy diver Jim Church, who taught and wrote about underwater photography for 30 years before he died in 2002, the school is run by Mike Haber and Mike Mesgleski. The Mikes worked with Church for 15 years and pride themselves on one-to-one teaching skills both above and under the surface. The school runs nine trips a year to the Cayman Islands, Belize, Turks and Caicos Islands, and Galápagos Islands, among other locales ($1,650 to $3,250, excluding airfare; 800-348-2628; aggressor.com). --ELLYN SPRAGINS
