After you finish The Perfect Landscape, talk to Vyv again, and he will tell you that he has a new job for you.
This time, the journalist needs shots of Angelgard, which is an island close to Galdin Quay.
Objective: Head to Galdin Quay
After you start the quest, which is very easy to complete, head back to Regalia, and fast travel to Galdin Quay in southern Leide.
Objective: Take an Attractive Photo of Angelgard
When you arrive at Galdin Quay, cross the dock that connects the parking spot and the diner.
Go around the restaurant, and head downstairs to Dino’s location (A Gentlemen’s Agreement story quest).
Close to Dino the jeweler, you should see an icon that marks one of the locations from where you can take a picture.
Again, it is important to take the photo during the day. At night, Prompto will refuse taking the picture.
While facing the water, take a pic with the large island on the horizon. It should be similar to the one above.
Objective: Report Back to Vyv
Head back to your car, and drive back to Lestallum.
Show Vyv the photo with Umbral Isle of Angelgard, and in exchange for your service you will receive 7,500 Gil.
Aftermath of the Astral War side quest is also unlocked when you finish An Eye for Islands.
