You might make sure it is well protected if you go out in a boat, it can get a little wet. We/ve never had to take any other precautions (like, regarding humidity) other than just assuring it doesn't get physically doused. Also, remember to take the camera and film in a carryon, not the checked luggage. If you have been following the board for any length of time, you should have noticed references to zip-loc bags. Bring some, they come in quite handy for all sorts of things.
