All photoshoots at NDK are organized by attendees; we the staff play no part in the selection or organization of any photoshoots. Most photoshoots are organized on the forum; when you're ready to organize a photoshoot, create a new thread in the
Cosplay board.
Common places for photoshoots include the grassy area in front of the hotel, on the side of the hotel near the bar, and in the lobby near the Trading Post (the Starbucks/gift shop). Generally, any out-of-the-way place is fine, so long as you don't interfere with the traffic in the hallways. (Panel rooms aren't OK, however, since we almost always have something going on in every room.)
