Let's try reviving this thread one more time. I like it too much just to let it go.
Easy: Eiffel Tower
Hard: Eiffel Tower at night
Expert: Eiffel Tower at night during Halloween Haunt
Just a suggestion that might help keep this going: try going a little bit easier on the categories. Think about what you would take a picture of when you're at the park. A kiddie ride might seem like an easy thing to take a picture of, but if you had a camera with you at the park, when would you really stop to take ride pictures in Planet Snoopy? Does anyone (except maybe BB1 ) take pictures of the slides in the water park?
At least in my opinion, the 'easy' picture should be something fairly obvious or broad. The 'easy' one should be the one that any Joe Schmoe with a camera could feel comfortable jumping in with, because, well... It's supposed to be easy. I don't mean to call out specific people's ideas, but on their first visit to the park with a camera, how many people think to take a picture of the cannons on White Water Canyon or Diamondback's test seat? (Again, they're absolutely great ideas--I'm just suggesting that they might be more appropriate as 'hard' or 'expert' pictures.) Some really great examples from the thread: closed WindSeeker, Delirium, a picture in the park on a sunny day, etc.
The 'hard' picture should up the ante a bit--but within reason. Make those pictures the type that someone who's taken several pictures at the park would take. Bring on the pictures of squid hats, Vortex mid-inversion, Alive Dinosaurs, obscure park signage/wind vanes, sculpted topiaries, etc. Don't go super over-the-top; that's what the 'expert' picture is for. This is where you ask for the not-so-obvious details of the park, like the bear on the way to Soak City, the Emporium, Backlot Stunt Coaster's 'splashdown', or SBNOSOB. For me, this is the easiest level at which I'll request Haunt photos, because apparently people just don't take many pictures during Haunt.
The 'expert' picture is where you let your imagination fly. Make this your 'Don Helbig doing a handstand atop a blue ice cream cake' suggestion, assuming Don's ever been caught doing such a thing. This is where you ask for things that people wouldn't normally take photos of at all. It's also where you ask for pictures from special events, because not everyone's going to have been there. Ask for Soak City slides and pictures on the fences, Racer stopped on the lift hill, Planet Snoopy rides, Flight of Fear with the emergency lights on, or behind-the-scenes Beast photos.
Again, these are only suggestions. I'm not trying to play moderator or change the rules; I'd just like to see this thread keep going because I love seeing people's photos!
