It's time for some reconnaissance. Start by making your way towards the lone target, which is the conveyor. Stand on top of the nearby post next to the giant ice statue, then zoom in enough and take the picture. The Temporal Sprocket is in the feet of a pterodactyl flying around, so it might take a bit to get a good picture. The Gravity item is in the hands of some penguin, so make sure you get to as high as ground as possible to get a good shot.
After you take pictures of the three items, Bentley wants you to investigate the arena. There's a rope that leads up to the spot where you need to be, so go there and you'll spot someone that doesn't belong in this time period. Take a picture of him and that will end the mission.
