Inmates sleep on the steps of a ladder inside the Quezon City jail at night in Manila in this picture taken on July 21, 2016.

Jonny Joo, 23, visits derelict malls, stations, towers and other places because they remind him of Silent Hill – a psychological horror video game which was made into a film. “When I first started exploring places, so many would remind me of the game. It was a world I was kind of obsessed with because of how dark and eerie it looked”, Joo said. His book, titled “Empty Spaces”, will feature 116 images and is being released this week.
