In order to take photographs, you first need to repair Beluga's camera, which Sammy broke. You can find camera parts (there are ten of them) by solving puzzles. Once you have them all, you have to fit them into the camera shell, which appears as a minigame in Professor Layton's trunk. Once you have repaired it, the game instructs you on how to take photos. In certain scenes, there will be a camera icon beneath the Professor's trunk. Click on that, and you will take a photo. These photos each have three minor differences from the original scene. If you visit the camera in the Professor's trunk, you will see a photo album that contains that pictures you have already taken. The original place will be on the top screen, while the photograph will be on the bottom. You will have to pinpoint the three differences. Once you do, you can revisit the place. Two of the places that had differences in the photo will hold hint coins, while the third will have a hidden puzzle for you to solve.
