Alex currently shoots with Sony cameras in Nauticam housings. Alex has collaborated with Nauticam since Edward Lai founded the company, and has been involved in the development and testing of many of their innovative optical products, such as the SMC, MFO, WAPC, FCP and EMWL. “Nauticam are deservedly the market leading for professional underwater housings and have revolutionised the capabilities of underwater imaging with their innovative and advanced products. I have never been paid to use any brand of equipment, in a competitive market I simple choose to use the equipment that gives me the unfair advantage in getting the best possible images.”

Alex is an Ambassador for Mares. He is also a Team Diver for Fourth Element. He is also very grateful to Retra, Backscatter, Zen, Marelux, Kraken and RGBlue for support of his underwater photography. Alex was also the inventor of Magic Filters, the filter that revolutionised available light underwater photography with digital cameras.

Alex’s Underwater Photography Workshops have become a must-do in photography circles and he runs them regularly throughout the year, at top diving destinations around the world. He also hosts the Underwater Photography Reboot, the online class teaching underwater photography. And for more informal teaching currently appears as the expert on YouTube’s Underwater Photography Show (over 150 episodes) and previously appeared on (more than 200 episodes) of YouTube’s Wetpixel Live. Both channels offer easy-listening education.

As a marine biologist, Alex received both his undergraduate degree (BSc Hons) and his Ph.D. from Southampton University (both at the National Oceanography Centre) and was awarded in 2002 the Norman Heaps prize from the Challenger Society for Marine Science as one of the UK’s most promising young marine scientists.

Alex Mustard is one of the world’s leading underwater photographers; his images celebrate the extraordinary diversity of marine life in the world’s oceans. His wide-ranging portfolio includes everything from startling macro shots of fluorescent coral species to large-scale scenes of barnacle-encrusted shipwrecks resting on the ocean floor.
