cjames:ssra30, saw that you are in Lembeh in 3 days, where are you staying?
I'll be on a liveaboard, the Panunee.
I am not familiar with your camera but if it has shutter priority mode or aparture priority mode then I would use either.Kompressor:I have been setting it in auto-mode.
Generally I prefer aparture priority mode so I can control depth of field better and just check the shutterspeed that the camera choose to make sure that is not too slow.
If it is too slow, just keep going up on wider aparture (smaller F number) until the shutterspeed is adequate.
