I went to East Greenland in September and sailed through a number of the Fjord systems. We had amazing water, which is common deep in Fjords. Coming home I realized I next year when we go back I want to work on Over / Under photo's of Icebergs. Living in Seattle I don't really have a great place to practice on something of that scale so I'm hoping to get some advice, especially around lighting.
Gear: D850, 8" Dome Port and a Sigma 14MM F1.8 lens. What I'm struggling to understand is what type of lighting I need. Clearly strobe lighting is required, but being new to this, do I need something with a high guide rating? We shoule have decent ambient lighting and the water tends to be quite clear generally and very calm.
Thanks for the tips. I'm completely new to underwater photography so hoping to get a decent setup and then head into some of the Alpine lakes around me this winter to practice.
