This mission is given to you by Lester, who can be found as the "L" mark on your radar. Get in the car with Lester and head for the jewelry store. Walk around to the back where the actual store is located and head inside. Enter the camera mode for your glasses to take a photo of three things here, the security cameras, the vents and the keypad for the alarm.
You can find security cameras all over near the ceiling, so take a photo of just one. For the vents, there are two behind the sales lady (who you will talk to for a distraction). They are located at the top of either of the pillars, and they might be slightly hard to see. As for the keypad for the alarm, it's on the wall next to the door to the left where you entered.
Once you get all three photos, exit the place and go back to the car. Go around the block and look for a way to get onto the roof. You find a place under construction, so go inside and find the ladder that will get you onto the roof. Climb the nearby section of the building, then make your way across to the marker to the highest point. Take a picture of the vent system, which is surrounded by barbed wire, then make your way back to the car. Drive back to the factory with Lester and it's time for a choice.
|The Heists in this game usually have two different paths, with different missions leading up to the finale, or the actual heist. For the jewelry store one above, you have the option to go Loud or to go Smart. Whichever option you choose, you will have to pick a crew. The better the stats of the people you choose, the bigger a cut they will want, so choose accordingly.|
