David first met and dived with Amanda on a tiger shark expedition to the Bahamas in 2008.   Although Amanda’s award winning body of work is very impressive, it was her ability to dive with sharks and capture their  elegance, beauty and power that immediately impressed David. 

Amanda began her love for photography over 20 years ago and is rarely seen without a camera in her hands.  Born and raised in Los Angeles, California; she received her Bachelor of Arts in Professional Photography while attending Brooks Institute of Photography with a focus on advertising photography.

Amanda's concern for the environment and passion for the underwater world quickly merged with her photography.  Her desire to help the general public embrace the Earth's beauty manifests itself with every image she produces.  Amanda hopes that bringing awareness of the world surrounding us will inspire individuals to get involved and actively support the conservation and preservation of these fragile resources.  More information about Amanda can be obtained through her A Cotton Photo website or A Cotton Thought blog.


In an effort to meet the demands of all the projects on which we work, we contract with a variety of experienced and professional crew.   All are leaders in their respective fields and continually demonstrate exceptional work skills.

  Austen Atkenson  -  Executive Producer

From a very young age two things stuck with me that I held an unrelenting zeal for, creating art, and the underwater realm.  All it took was a glance at my mother’s own sketchbook, and seeing the great Dr. Eugenie Clark in action in the film National Geographic: The Sharks to get the hook deep into me (which stays still to this day, and only gets deeper with age). 

Pursuing art was easy, I took a class every year in school, doodled whenever, and wherever I could, and obtained a bachelors degree for graphic design. I learned to create in many fashions and spent my time drawing, painting, crafting, designing, and photographing as often as I could. It wasn’t until later in life however, that I was able to pursue SCUBA training. But when I did, I followed that with the same enthusiasm I had art. I’ve now reached heights in my training that few other divers would dream to pursue, and I have no intentions of stopping.

Combining the two, I now have a way to share the things I enjoy most with others through my photography and design work.  I hope to continue to share my adventures for years to come.  Visit her website at:


  Kristi Bernot   -  Graphic Artist  / Underwater Photographer

Will began working and diving with David in 2007 as an underwater photographer on an advertising campaign for Gates Housings.  He is now working with UEV to produce a television series, currently in development, about sharks.

Will is a Quebec native and born adventurer.  Although he is a master at fashion photography, it was his natural ability at technical diving and his gentle way with sharks that caught the attention of his peers and the scuba industry at large.   He has worked on two IMAX features to date, and his photography can be widely seen throughout the diving industry in print and on the web for companies such as Gates Housings, Dive Rite, Whites Manufacturing and Undersea Expeditionary Video Services. For more information on Will Allen or to contact him, go to his web site at:

David and Suzy met serendipitously in 2008 while attending the 2nd Annual Whale Shark Conference in Holbox Mexico.  Almost immediately Suzy began working with UEV as a Producer to develop a television series about shark behavior.

Former Director of SRI UK (until she relocated to South Africa), Suzy, a marine biologist, has worked with sharks in Australia, Djibouti, India, Honduras, South Africa and Tanzania. While working for SRI in Australia, she compiled a video catalogue of whale sharks at Ningaloo Reef spanning 5 years, led field expeditions onboard the Kairos to the northern Mozambique Channel, and contributed images of more than 150 whale sharks to the Ecocean catalogue. A world-class underwater filmmaker, Suzy is currently living and working in the UK.   Most recently she worked as an Associate-Producer and Underwater Videographer on “Sharkman,” a documentary which aired on the Animal Planet in the UK and in the US on Discovery Channel’s Shark Week. 

Los Angeles based Cinematographer David Warshauer spent much of his 20's chasing the world's largest swells.  While swimming in the impact zone of some of the world's deadliest waves in order to capture imagery of surfing, David developed an appreciation for the ocean's awesome power.  Over time his interest shifted to the ocean's vulnerability and the current threats to its delicate ecosystem.  Merging his love of cinematography and the ocean, his passion evolved into documenting the beauty and wonder of life under the surface. 

"When people can identify with marine life and see the ocean in new and interesting ways, they are more inclined to do something in their own lives to help preserve it."
