This feature is similar to the one in Fatal Frame 1. Simply finish the game once on any difficulty level. Save your End Game data, load it, and start a new game from the Bonus Features menu. At the beginning of the game, after Mio finds Mayu again, but before you head down to the village, you will already have the Camera Obscura in your inventory. The camera will still have all the attributes and bonus features you added to it from the last game, including the Shot Point bonuses you accumulated before you finished the game. Also, having your camera at the start of the game will allow you to capture the two ghosts you missed at the start of the first game, for the Spirit List.
