This is a difficult trophy to get, but it is possible. To get it, play mission 10 on single player.Once you are in the mission, clear the conference room and take out the target, but be sure to take the bronze statue on the crate on the left of the room before leaving.
Go through the first checkpoint and continue on to the second. Pass through it but then double back down the steps and follow the sign down to the right staircase. At the bottom of the stairs enter the far door, put the statue in the hole in the wall and it will open. Head inside but don't kill anyone. Move to the center of the dance floor and follow the on screen prompt. You will then earn the trophy.
At the start of a leve, press the following buttons to change the screen filter effect:
Up, Up, Down, Down, Left, Right, Left, Right, X, Circle
Note that there are 5 different filters, so keep repeating this code until you've seen them all.
