1. You need to be standing around your vehicle in third person mode. 2. Select sticky bomb from your inventory and then press and hold the button that you’d normally use to throw it (being RT for Xbox, R2 for Playstation). 3. While still holding the relevant button, open up the Snapmatic. 4. This is what allows you to take the picture in third person. From here you need to move the camera angle to how you want it. 5. When you’re reading, release the throw button and your player should crouch down around the vehicle and plant the bomb. 6. While they are doing this, you need to take the picture and voila, you should have a third person, non-selfie, Snapmatic!
