I am about to go on a vacation of a life time. I will be flying to Tahiti where I will spend two days driving around the island taking pictures. Then I will be flying on a small plane stopping in a couple of islands in the Tuamotu’s ending up in Mangarava where I will be getting on a large sailing yacht that has competed in the round the world yacht races. We will take this boat to Pitcairn island where I will be diving on the HMS Bounty of the Mutiny on the Bounty story and staying with the descendants of the mutineers. When I get back to Tahiti I will be taken up in a small plane by the people I will be staying with to take pictures of Tahiti and the surrounding islands. In writing this I still cannot believe it is me going on this trip. I am not a professional photographer but I like to take pictures and I have what I think pretty nice gear. Since I will most likely have only one chance to get the perfect shot I would like to ask the opinion of someone who has shot in the situations I am about to describe and what I should do. The equipment I will be taking will be
Nikon D3, Lens I will take are Nikon 14-24, 24-70, 70-200 II, 50mm 1.8 and if I can fit it in the bag 105mm 2.8 for taking pictures of people. A Cullmann Magnesit 525C Tripod. Is there anything I can do without? Or is there a better lens I could take?
I have purchased a Nikon AW-100 for taking pictures underwater of the Bounty. The Bounty is in shallow water so the depth limitations of the camera will not be an issue. I will also use this camera for a quick point and shoot.
I have also purchased two Go-Pro cameras and the 3D (just for fun) housing for it. Does anyone have any experience using the Go-Pro in 3D? Is it worth taking? Or should I concentrate on using the GoPro’s by themselves.
Since there is no light pollution my plan is to spend the night on top of Pitcairn island and take pictures of the island by the light of the stars and of the stars themselves. The moon will be ¾ full when I arrive to almost nothing when I leave. What lens and settings should I use to take these pictures at night?
My weakness is taking pictures of people, of the lenses I am taking what is the best lens to use? In my research I think the answer will be the 105mm. If I cannot take it what is the second best and any tips on camera settings will be greatly appreciated.
Last question, what lens should I take on the open plane that my friends will use to fly me around Tahiti? Because it is an open small plane I don’t think I will be able to change lenses.
I would really appreciate any advice

Is there a general rule on Depth of Field? The attached photos were taken with my Canon SX20 and set on auto. I didn't know there was manual buttom on the camera until I went to a outdoor photography class. Wow! I sure learn alot from that class. So I went out and purchassed a Canon T2i. Went from 12 megapixel to 18 magapixel, F/8 to F/25 plus alot of other choices. My question is what F stop do you set when shoting landscrape? Thats why I attrached the photos that I did. Thank you for any ideas. Oldhilker
