Chicago photographer Mark Hersch has so far restored about 300 vintage images of his city, helping to recreate an understanding of how things worked 100 years ago.
His trick is to take a new image in the exact same spot and blend old and new to create a three-dimensional look at the past.
A lot hasn't changed ... I sort of had that eureka moment, you know, [that] 110 years ago a photographer stood on this very spot, you know, a little box on a tripod, a blanket his head, and he took that shot — POOF! — and then I go out and take the shot, and I just think there's something magical about that.
And there is!
