Residents secretly photographed in a luxury building in Tribeca are up in arms over a photographer who took pictures of them without their knowledge. Artist Arne Svenson fully admits to secretly photographing his neighbors and displaying them for sale but claims it is part of his art.

The secretley-taken candid photographs of the residents are being sold at a new photo exhibit in a Chelsea art gallery. The photographer, who lived in the building across the street, says he hasn't done anything wrong. He says that because the photos don't show full faces, his subjects remain anonymous-even if they didn't know they were being photographed. They show the residents at the tony building doing a wide range of personal activities-cleaning, watching TV, napping, and carrying their sleeping children to bed.

The shots now on sale for up to $7,500 each at the Julie Saul Gallery in The Neighbors," an exhibition that opened Saturday.

The are of residents of the exclusive 475 Greenwich St apartment block in Tribeca. From his second-floor apartment across the street at 125 Watt St., Svesnon secretly photographed his neighbors-and they're fuming

Residents who live in the Greenwich Street building, where penthouses fetch up to $6 million, are considering legal action.

One resident with children in the buildings who appeared in a Svenson photograph said, "This is about kids. If he's waiting there for hours with his camera, who knows what kind of footage he has. I can recognize items from my daughter's bedroom."

Another parent, Clifford Finn, told press, "A grown man should not be able to photograph kids in their rooms with a telephoto lens. You can argue artistic license all you want, but that's really the issue here. I'm sorry, but I'm really bothered by this."

Those with children, particularly, are considering legal action, but Swenson says is brashly unapologetic.

The artist's statement accompanying the exhibit reads,

"For my subjects, there is no question of privacy.  They are performing behind a transparent scrim on a stage of their own creation with the curtain raised high. The neighbors don't know they are being photographed; I carefully shoot from the shadows of my home into theirs.

Experts in privacy law said the residents will have more luck in a civil case rather than a misdemeanor criminal proceeding, because their faces aren't fully visible.

Experts in privacy law have advised that residents would likely have a better outcome in a civil case over a misdemeanor criminal proceeding because their faces aren't fully visible.
