How do you use the Metal Gear Online camera ?

Question

The one in the L2 Button inventory.

Answer 1

you equip the digital camera (item) then you can take picture in first person view by clicking r1 I believe.

If you want to take picture in third person view, you have to change mode (the option is available when you selecting the camera while the L2 inventory still up) you have to use a second controller and click r3 I believe.

If you only have one controller you can simply switch your controller port to slot 2.
