Hi, I'm Alex, I'm a pro u/w photographer and operate Dive4Photos, an underwater photography training facility in Thailand (www.dive4photos.com). I also lead trips and conducting workshops in other destinations. I have been shooting underwater for over 20 years, have been regularly published in u/w photo mags since 2011.
I have been shooting with Nikon cameras since 2006, now using the D850 for most stuff and the D500 for Blackwater, paired with a variety of lenses, Nauticam Water Contact Optics and mainly Retra Flashes, but also Backscatter Miniflash MF-2's where appropriate.
