Inside an abandoned film school in Ohio. (Johnny Joo)

Photographer and urban explorer Johnny Joo says he has always enjoyed uncovering and shedding light on hidden places. In his most recent exploration, Joo discovered an abandoned film school in his home state of Ohio.

“This particular location was found out of a random drive into town, where I thought it was just a regular, ordinary school, but found myself to be completely wrong, in the best way possible,” Joo told weather.com.

Inside the building, the walls were crumbling and decaying."In places where temperatures can go below freezing during the winter months, the freeze-thaw cycles can take a toll on abandoned buildings," said weather.com meteorologist Nick Wiltgen.

When Joo walked into the school he saw a theater with a sign that read ‘”Welcome to your set from the art dept. Good luck and enjoy yourself!’ “ He figured he was in a set that was used for a theater class.

As he went farther into the school, he started seeing boxes with familiar branding: Kodak, Olympus, and Fuji. It was when he noticed old lighting and camera equipment that he started to realize he was in an old film school.

“With the discovery of each new room, my exploration had only escalated in excitement, building rapidly with each room as I crossed from one end of the hallway to the other,” Joo said in a statement.

The Cleveland-based photographer said he snapped photos of every inch of the abandoned building, making sorting through the photos a challenge.

Joo became hooked on photographing abandoned structures in high school after he made his mother pull her car over when he spotted a crumbling barn in Kirtland, Ohio.

“The way the roof was collapsing in on the foundation was amazing and I loved the way decay and overgrowth could take over a place, making it almost abstract and surreal in its own post-apocalyptic and artistic form,” he said. “I love figuring out the history behind all of these places, it interests me so much to see past lives.”
