"[I felt] that society didn't need me, and it would move along just fine without me," he told Business Insider.
However, Yamada is an eternal optimist, and he decided to turn the downtime into something productive. "I decided to make sure one positive thing happened in the midst of that uncertainty, and that was to learn photography seriously," he said.
Greatly inspired by Brandon Stanton, the photographer behind Humans of New York, Yamada knew that he wanted to document people. He decided to add his own magical take: including levitating objects in the shot.
Photographing both his subjects and their prized posessions, Yamada has now documented a handful of Chicago's own successful entrepreneurs for a project he calls "The Uplifted".
As for his process creating a final, finished image, he said, "I usually capture a subject and objects separately and combine the two later in Photoshop."
Ahead, 13 Chicagoans and their stories, as told by Yamada.
