I am very much new to underwater photography. Starting with snorkeling. I shot last time with my Canon G5 and it had an underwater setting. I now have a new housing for my Nikon D80 and we are heading by to the Virgin Islands. Any advice on where to begin on setting, manual, automatic, aperture??
I also have been looking for a good case or rolling backpack for the upcoming trip. I have looked at Pelican, Seahorse and Lowepro. What advice good and bad to some of you have? I would love something that could be carry on after reading some of the stories about going through some airports.
