Progressing through the buildings generally involves the mainstay of finding a key of some type, but the game does mix things up by including a few simple puzzles and presenting seals that may be removed by photographing certain locations with your camera. If your twin is with you, she'll also sometimes aid you by stopping in front of important rooms or giving you a verbal clue to indicate that something worth noting is nearby. The village's dark history is gradually revealed, both through grainy black and white film sequences and through the abundance of documents you'll find scattered as you proceed. There's also at least one genuinely "friendly" ghost in the game who believes you are someone he already knows, so he'll often give you hints for your objectives--if he's available. You gradually get a complete picture of the town's denizens through numerous diaries, memos, and notebooks as well as by grabbing choice photos--when the opportunities arise--by using the game's core feature: the camera obscura.
You find the camera soon after arriving in town, and the device serves a wide range of functions. It can be used to defeat hostile spirits, reveal clues, unseal doors held closed with spirit power, and catch hidden ghosts. It can even just take snapshots, if you'd like. You need film to take pictures, and, unlike in the first Fatal Frame, this iteration of the camera thankfully comes preloaded with a mysteriously inexhaustible supply of low-grade film. This allows you to hoard the more powerful film you obtain for combat, while letting you snap pictures of clues and the like to your heart's content. Otherwise, the camera handles just as it did in the previous game. So pressing the circle button causes you to enter first-person mode, and lining up things in the capture circle allows you to photograph hints, or it allows you to damage spirits. The capture circle glows green for hints and hidden spirits, and it glows red or orange when you've got a lock on hostile spirits. You can upgrade the abilities of the camera via lenses and other special items you acquire during gameplay. You'll spend something called "spirit points" to do this, which you'll earn through special photos and through battle.
