I am with a group called Serve On since Last January, if you want to know what we do, please check out the link. https://www.serveon.org.uk/ I take photos of their training excercise's and have just began training myself. In June I hope to go to Snowdonia and up the mountain photographing the training exercise. What I want to know is several things like: What's the best way of protecting the camera from the elements? I've heard the weather can change in minutes. What are the best settings, eg: iso, speed, white balance? Do I take the battery out at night when not in use? Where is the best place to get a genuine Nikon battery? Is 18-105 lens good to use up a mountain? Having never climbed a mountain. or EVEN been to Wales before, I'm not sure what to expect. I'm a bit worried I've bitten off more then I can chew, I'm not a pro so I hope they don't expect too much of me.
