This can easily be earned in the first few minutes of Chapter 1. Simply make sure you enable Photo Mode (it is disabled by default) in the options menu. It is the last option at the bottom in the Gameplay settings.
Then, after the initial cutscene (Photo mode is disabled during cutscenes), when the pirates are about to attack, just press down on the D-Pad (
), and you will enter Photo Mode and the trophy will pop. You don't have to do it then, and it will work the same at any point in your play-through. You do not need to actually take a photo to unlock it.
Thank you for positive votes! Please comment if I've made a mistake or you have anything to add. Stay tuned, as I'll be adding many more for Uncharted: The Nathan Drake Collection as I play and unlock them. Feel free to add me on PSN! Happy Hunting :)
