Capture 50 Photographs for your Journal.
As you play through the game, periodically a camera icon will appear in the top-left of the screen - when this happens whip your camera out (Up on the d-pad on a controller) and take a picture. After 50 it'll pop.
This isn't hard, but is worth taking all opportunities for as you play through - to minimise mop-up after completing the story.
