Hi I just got word that most likely I will be going on a Fly fishing trip in the spring to film some pros (my step brother and his friend). The video that comes out of it will be entered into a fly-fishing film circuit. My question is what kind of extra gear would I need to spend a week or so in the wilderness. I have a dvx 100b. My concerns are moisture, power, cold, protection of my equipment, etc. Any other advice or people's experience shooting in that environment would be great. Thanks.
