A new feature in Ultra Sun & Ultra Moon, the Alola Photo Club lets you show off your Pokemon to the world and cherish your most precious memories as you journey throughout the region.
You get access to the Alola Photo Club before you leave Melemele Island from Hau’oli City; in fact, you are more or less forced to go into the building and take a photo to learn what it’s all about. Afterwards, there is another facility in Konikoni City and you can go to either at any time to take a photo of your Pokemon.
For the most part, if you want photos you will have to go into the facilities to start a photo shoot, but every time your Pokemon evolve, you will be able to do an impromptu photo shoot if you accept Rotom Pokedex’s request.
Taking photos with your Pokemon builds up their affection levels towards you similar to playing with them in Pokemon Refresh. Addtionally, if you took a photo because Rotom asked, after you are done you can play in the Roto Loto!
