Note: This is only available for returning players that upgrade from the Xbox 360 or PS3 version of Grand Theft Auto 5 to the PS4, Xbox One, or PC version of the game. Successfully complete the main storyline. Then while playing as Michael, find the four murder mystery clues written on various walls in Los Santos. You will hear a sound after each clue is viewed. Take the submarine out into the ocean off the west coast, and then swim down to the bottom with the scuba gear to find a drowned woman chained to concrete on the seabed, near a sunken ship. Next, go to Richard's Majestic film studio after 9 p.m., and step into the yellow mission circle. While in the office, look at the letter on the desk. It will lead you to the mineshaft. Use a gun with a flashlight to navigate your way to the bottom of the mine to find Issac's corpse, which will be added to your contacts. Select that contact to apply a black and white noire filter to the graphics. This filter is also a reference to L.A. Noire by Rockstar.
