Rotom Pokédex/Functions/Poké Finder

The Poké Finder (Japanese: ポケファインダー Poké Finder) function allows players to take pictures of Pokémon in locations where the icon on the player's bottom screen turns into that of a camera. It can be activated by pressing the R button or tapping the camera icon in those select locations. Pictures are then evaluated with a "Thumbs-Up" score. Pokémon found through the Poké Finder will be registered as seen in the Pokédex.
