Hi,
I will be going to the Galapagos in a bit more than two months. This promises to be a very exciting trip, and photography should play a big part in it. However, the trip is going to involve a lot of water: it is based off a catamaran and almost all the transportation is done on kayaks (to be more specific, inflatable sit-on-top vessels), though there probably will be a zodiac for support as well. And of course, it being the galapagos, a lot of snorkeling.
My current equipment is not tropicalized (main camera is a Nikon D90, I will also take my Nikon FA if I manage to revive it, or buy a second hand FM if I can't, and I'll probably take the large format for some landscapes) and I very much doubt it will appreciate being that close to that much water.
So, my questions are: which solutions do you recommend using? Are there waterproof bags that you could vouch for, to the point that a drop in the sea would not damage the content? Should I forget entirely about bringing the DSLR on board and only take a P&S? What about ambient humidity, then? If it can kill 5D MkII in Antarctica, it probably can kill a D90 on a tropical island.
And are there any cheap solutions for low-depth underwater shooting? I have nowhere near enough money to invest in a good SLR casing, but are there maybe dedicated P&S that actually work for that kind of things? Or miraculous film-based solutions?
I have never shot that close to water (my thing is mountains), so any help would be very welcome here!
Thanks.
