One of the many sidequests you'll take on in is the Alo-Happy Photo Rally. Given to Majima by the employees of the Alo-Happy tour company, who are trying to compensate for a failing promotional program, this sidequest involves taking pictures of a series of locations around the map.
These may range from iconic tourist destinations to one-of-a-kind moments, and are spread throughout Honolulu, Rich Island, and Madlantis.
This sidequest begins in Chapter Two, when Majima must stop by Alo-Happy Tours on his way to a main quest objective. From then on, you may occasionally see a camera icon pop up as you're wandering around town, signifying that you can earn a photo rally stamp there.
You can also check your progress and get hints on your remaining photos by checking the Photo Rally app in Majima's smartphone, accessed via the pause menu.
In case you need a little more help, though, here's where to find all the Photo Rally spots throughout 's Honolulu map. This joyous little sculpture is located right next to Tony's Lemonade Stand, which featured prominently in an substory.
