Brassaï had Paris. Weegee had New York.

Mark Cohen, well, he has Wilkes-Barre.

He has lived in the down-on-its-luck small city in northeast Pennsylvania for 69 years - his entire life. He started taking pictures of car wrecks for t he local newspaper while he was in high school and ran a photo studio from his house for more than 35 years. In between the weddings, portraits and commercial assignments - on which he raised a family - he shot quirky street images for his own pleasure.

The photos were relentlessly sad, often disturbing. He was not interested in documenting, but in making images that were “a psychological imprint” of what he was looking at. Holding a little Vivitar flash in one hand and his Leica in the other, he waded right into his photographs, running up to people and photographing them from a few feet away.

It's an approach that's been repl icated by other street photographers, but under much different circumstances.

“I'm photographing in the backyards and alleys of Wilkes-Barre and nearby coal towns,” he said. “On Fifth Avenue in New York, there's a lot of people there. If you go into a back alley in Elmira, it's not the same thing - and it's very suspicious to set off a flash.”

His habit of approaching unsuspecting subjects has led to altercations, including a few that turned physical. More than once, while making a detail of someone's clothing with his 28 mm lens, he has been called a pervert.

Though he photographed almost exclusively in Wilkes-Barre and two neighboring counties, he often took a bus to New York to see exhibits and take classes. In 1973, John Szarkowski gave him a one-man show at the MoMA and included him in the 1978 group show, “Mirrors and Windows: American Photography Since 1960.” His photo (slide 2) appeared on the cover of The New York Times Sunday Magazine on July 23, 1978, in an article by Hilton Kramer called “The New American Photography.”

In the fairy-tale version of his life, he might have gone on to move into a SoHo loft, hobnob with artists and become a luminary in the photography world while continuing to produce innovative work.

That's not what happened.

He had to support a family, and there was not much of a market - or money - for street photography. He recalls exhibits where his prints sold for $75, next to photos by Harry Callahan selling for $150.

So he stayed where he was and produced his personal work between weddings and portraits. Wilkes-Barre may not have been the best place to be an art photographer, but it turned out to be a pretty good place to develop his personal work.

There are many street photographers in big-city galleries showing images from Manhattan or Paris. But Mr. Cohen has Wilkes-Barre all to himself. Though he insists that his photos are not documentary, the Rust Belt city and two nearby counties have been a perfect canvas for his upsetting imagery.

“You can make these pictures anywhere,” he said. “You could make them in Cincinnati or in Elmira, they don't have to be made in Wilkes-Barre.”

And while Mr. Cohen is not a household name in photography, he has a small, devoted following. His book, “Grim Street,” published in 2005 by powerHouse Books, has become a cult classic among street photographers. In the last decade his prints started selling - for much more than $75 - in galleries in New York and Los Angeles.

He has closed his commercial business and is c oncentrating on his personal work. He lives in a 4,000-square-foot house and now feels that staying put allowed him to produce better work.

“If I came to New York City and started horsing around and getting in long aesthetic discussions with professors of art, or hanging out with artists at the Cedar Bar? It would have been incredibly distracting.”

Images from Mark Cohen's “Grim Street” series will be on display at the Third Floor Gallery in Cardiff, Wales, beginning Dec. 8 through Jan. 27.
