Keoki & Yuko Stender

Underwater photographer, PADI Instructor, Scuba Repair Technician, Recompression Chamber Operator, and marine educator in Waimanalo, Hawaii. Employed as a Diving Safety Specialist at the University of Hawaii at Manoa. AP Diving Inspiration rebreather diver. I enjoy observing and photographing marine life whether tidepooling, snorkeling, technical diving, or visiting aquariums. I was introduced to the ocean at an early age, trolling and bottom fishing with my father. I learned to surf (kneeboard) at 12 and began building surfboards soon after. To stay busy while the surf was flat, I started free-diving to spear fish and collect shells, and got my NAUI Scuba certification in 1984 (I take only pictures now, not live animals). I attended the Kamehameha Schools, Windward Community College, and the University of Hawai'i at Manoa and earned a certificate from the Marine Option Program (MOP) for work in marine education and biological surveys on Moloka'i, Kaua'i, and at Hanauma Bay. Employment history includes training dolphins, diving, and veterinary lab support for the Navy, Windward Dive Shop, manager of Midway Sport Diving at Midway Atoll NWR, marine educator/dive officer/boat & recompression chamber operator with Rapture Marine Expeditions, survey expeditions of the Northwestern Hawaiian Islands, and educator for the Waikiki Aquarium. Other interests include native Hawaiian plants, wildlife, jazz, and airplanes. Yuko & I attend New Hope Christian Fellowship O`ahu.

Photographic History

My photographic background began in 1990 while teaching fish ID classes for fellow MOP students. The school's slide collection was limited and quality varied so I decided to teach myself how to use a real camera. After wasting lots of film taking horrible little fish photos (the wrong subject for a Nikonos), I spent all my savings for a housed autofocus SLR system. Within a few dives I was completely hooked on underwater photography! I contribute images to the Marine Option Program, Hanauma Bay, and other educational programs, and sell stock images for local hotel publications, calendars, and marine life books including Hawaii's Fishes, Hawaii's Sea Creatures, and Corals of the World. We use Pentax SF-1, PZ-1, Z-1, and MZ-S film SLR's and *ist DL digital SLR's with 15mm fisheye, 24mm, 50mm macro, 90mm macro, 100mm macro, and 90mm + 2x teleconverter, Ikelite housings, and dual Substrobe 50/100's. Fujichrome Velvia 50 was our favorite film and it was processed at home. Slides are scanned with a Canon F4000US film scanner. Yuko uses a Casio Z40 digital point & shoot housed camera & Canon G9 in an Ikelite housing, Substrobe 51, and Epoque 2x macro and Wide Angle lenses. Yuko & I are members of the Underwater Photographic Society of Honolulu.
