Warning: You can't complete this quest or any of Vyv's quests during the night time because the lighting is too poor to take a picture. Be sure to rest somewhere before heading out to take the Photograph.
You'll receive this quest after completing The Perfect Landscape from Vyv. For this quest what you'll need to do is head over to Galdin Quay and to the same side of the town that Dino is on. There will be a little photo quest marker on the ground that you can stand in and take the photo you need.
Once you've obtained the photo, a tip is to open your menu up and go to Map, from here you can quickly fast travel to your vehicle then fast travel back to Lestallum where Vyv is. Completion of this quest will open up the next one in the chain, Aftermath of the Astral War.
