This one is a little tricky, because the sketch in her journal makes it seem like it's a statue/trophy in Dana's room, which is farther down the hall. This is actually found in Victoria's room, directly across the hall from Max (where you start the game). A blue action figure is on top of a shelf to the left of the laptop, on the far side of the room. A white poster is on the wall behind it.
In order to enter Victoria's room, you need to talk to Dana (in her room down the hall, on the left), or Taylor (in the showers from the side hall on the left) to learn that Victoria is sneaking out.
Shine the light on the statue to make it glow and create a shadow on the poster for a few seconds, and the option to take a picture will then appear.
Any of the "optional photo" trophies can be easily obtained after finishing the episode by using chapter select and playing again in photo mode.
