Fleeting Youth, Frame by Frame

I stayed on the platform as the subway doors closed, because through the train windows, I saw a glimpse of melancholy—and I had to capture it.
Human youth is so fleeting. Sometimes it’s like a passing train: one moment, a bright-faced girl fills a window; five brief minutes later, it’s a weary elder in her place.
The art of photography is seizing that vanishing moment of youth—before it slips away.
