Just got my D3100. Haven't had much time to play with it and I'm planning to take it on a two week trip. What I would like is having it set up for anything that comes my way; that is if its possible. I do know based on searches that there are particular situations that would require different settings, but I was just wondering what I should change in the settings that would allow me to “get the shot” in most circumstances. I'm completely new to using a DSLR so not sure if there's a general setting that I can have it on to just take out the camera on the spur of the moment and take a shot. Any help or advice would be helpful either with the settings or what mode to use as well. I have 18-55mm and 55-200mm lenses. Which would be better to keep on the camera? Also what's the difference between these lenses? I mostly will be taking photos of my family and occasional scenery pictures.
