All of my underwater pictures are taken with a Nikon F90x SLR camera surrounded by a metall SUBAL housing. Lenses vary from 20mm wide-angle to 105mm macro. tele-lens. To retain the colour it is necessary to use a strong flashgun, even in shallow waters. Older pictures are with different types of Ikelite flashguns, photographs of the past 5 years are done with Nikon 103 or 105 flashes. I use slidefilm only and I prefer to use Fuji Provia (100 ASA) and Fuji Velvia (50 ASA) - especially for close-ups. For shots into the blue I like the Kodak Elite 100. To get them onto the web I use a Canon FS4000 slides-scanner.
