That was a challenge on the harder difficulty, those ghosts can really swarm you with projectiles and it is a challenge to keep avoiding while waiting for the recharge. Though really interesting idea of using the camera to change time periods, finding the ghosts through the hub location was a great idea.
It did take a little while to work out camera angles for the journal, though it really kept me focussed on the environment as I looked out for where the pictures could be. Some camera angles were a challenge to line up, but it was a fun experience.
