Welcome to the boards!
Feel free to use your camera anywhere - except the more obvious places (i.e. thrill rides, unless you really have a grip...but not roller coasters...). Things like Alien Encounter are hard to film because you are restrained. However, attractions like Splash Mountains CAN be filmed, just make sure to cover your camera from during the falls!
As for the animatronic shows, i.e. Carousel of Progress, Country Bear Jamboree, Enchanted Tiki Room UNM, Food Rocks, Timekeeper, the Cast Members request that you use no external lighting. This is distracting to other guests.
A random CM may ask you to put your camera away (possibly on a confusion of policy), but that probably won't happen as long as there are no distracting feautres on your camera.
Welcome, again, and have fun filming!

Many times, when policy says it's 'okay' to film, a CM may just say, there is no filming to you personally. Many people, if that is the case, hide their camera until the show starts. Or, if you have a better conscience, ask another Cast Member. (I.e. some knowledgable CMs allow filming with no lighting in the CoP. Others may say 'no filming at all' just because of those few distractions.)
Hope this helps!
