This is mostly about knowing where the snipers can appear.
The final yard starts out with three snipers. Halfway down the stairs, 4 will spawn on the left, and 2 ahead on the far tower; the 4 that spawn on the left will be randomly divided between the high up top room, and the ground room near the large metal crates. Once all have been eliminated, 1 more will spawn on the roof ahead. The last batch of snipers spawn on the roof again once up on the first crane.
Only approach the lazer in the final area when ready; enemies will start endlessly spawning upon getting near it and the objective for photographing it appears.

Nice. I didn't know the camera could point out where enemies are.
