I took these using a Nikon D700 with a Nikon 17-35 f2.8 lens using just the available light. The ISO on the camera was set at 6400.
Hey Paul, SURPRISE!
I was doing some "window shopping" this week just to check prices and see what was available with no intention of buying anything and came across a deal I just couldn't walk away from. The next underwater shots I take will be with the Nikon D700 in it's new Ikelite underwater housing and a Nikon 24mm f2.8 lens. I just couldn't help myself! (I really couldn't)
