Don Jolly profiles Shannon Taggart , photographer of séances, spirits, and ectoplasm. What is beyond the veil—and what ISO does it look best at?

Picture a photograph of a man with two faces — one grimacing in pain, one open-mouthed in ecstasy. They float in a field of darkness, lit red, connected only by a pale-pink thread of motion-blur. Is this an image of a man jerking his neck wildly, taken with a long exposure? Or is it the image of a physical medium, a person sensitive the invisible world of spirits, channeling an intelligence from beyond the grave?

The answer is yes — to both interpretations. And the photographer behind the enigma is an attractive, auburn haired New Yorker named Shannon Taggart. She's worked for glossy publications like Time, Discover and Newsweek — but for the last ten years, her passion has been photographing American and European Spiritualists, the strange remnants of the 19th century religious movement which brought the world dim-lit seance rooms, ghostly rappings and — most relevant to the present project — spirit photography.

Taggart's particular approach to spirit photography uses what are usually deemed photographic "accidents" to produce striking, supernatural images. Taggart is not a "believer," in the traditional sense, nor does she seem to debunk her subject. Rather, she presents a world where belief and unbelief are radically mediated by technology — and raises the possibility that in the age of omnipresent electronic image what is "true" may be a much harder debate than the skeptics suppose.

One of her recent subjects is an ectoplasmic medium named Gordon Garforth.

Garforth is a spiritualist. His religion, a product of the American nineteenth-century, holds that death is not the end of consciousness. For him, there is an eternal world of "spirit," and certain gifted individuals, mediums, are capable of conveying messages and energy from the other side. For some can even manifest various physical substances and effects, broadly identified as "ectoplasm." When he enters a trance, Garforth told Taggart, "You'll see masks spilled over my face. You'll see my hands change." It was just how the spirits worked for him.

Taggart was skeptical. "I'm thinking, 'Okay. Well that could mean many things," she said. "I didn't go into his séance expecting anything. I got to sit in the front row, about six feet away from him."

She kept a camera on her lap.

"He was seated in front of a low red light," she said. The room was dark, otherwise. After twenty minutes, the medium's wife announced that spirits were going to begin working with his hands. Taggart remembered the next moment very clearly: "He just brought out his hand. What I saw, with my eyes, was this regular hand just very gently and instantly — skip gigantic."

"I screamed out loud," she continued. "Which is very impolite in a séance situation."

Taggart's photographs have appeared in outlets such as Readers Digest, Discover Magazine and the New York Times. She's captured dance auditions and artists' portraits. Her approach is often unusual, and frequently relies on long exposure times, producing hallucinatory doublings, strange auras and smears of motion as her subjects move. When she photographed Garforth, the long exposure was mostly done to compensate for a lack of light. The resulting images are jittery and blurred — Garforth moved around. They also show the medium holding up a single, grotesquely inflated hand.

"I had that experience of seeing that hand get large," she explained. "I don't know how it happened. Whether it's a hand actually getting large in front of my face and I was creating a photograph that documented it, or whether it's that I was tricked somehow or I had a hypnotic experience and then my camera, through its dysfunction, mimicked that experience… I mean, all of those are interesting perspectives. I love that they're all there." She's been catching similarly ambiguous situations for over a decade.

Taggart grew up in Buffalo, New York. From an early age she was attracted to the nearby town of Lily Dale — a spiritualist community which has, since 1879, played host to many of the movement's most prominent thinkers and mediums. "I was raised Catholic," she continued. "A lot of Catholics actually go to Lily Dale for readings, because Catholic belief doesn't dismiss what is happening in spiritualism, necessarily."

Taggart's cousin once attended a "message service" in Lily Dale, a public assembly where mediums provide scattered communications to a curious crowd. "You don't know even which medium is going to be there that day," Taggart said. "Whoever it is stands in front and they pick people out with their finger. Then they give a short message from someone who's died." Taggart's cousin was picked out. The medium told her a secret, something nobody outside the family could have possibly known. At this point in the story she wrinkled her nose. "I don't know if I want to put all the details about this in the article – if you don't mind," she said. "You could say it's a secret."

"Of course," I agreed.

Driven by this strange incident, Taggart had a formal meeting with Lily Dale's Board of Directors in 2001, asking to make the town the subject of a long photographic project. "I don't know why, but they just welcomed me with open arms," she said. Her work in Lily Dale is still ongoing, and many of her images of the place are available on her website shannontaggart.com. From there she branched out into similar projects covering Vodou rituals in Brooklyn and working with mediums like Garforth. She's even taken a paranormal investigation course at Arthur Findlay College in England, "the world's foremost college for the advancement of spiritualism and psychic services" — at least according to its website. Still, Taggart doesn't consider herself a "believer" — or an "unbeliever," for that matter. When it comes to spirits and blurry photographs, the discourse often revolved around proof. Both spiritualists and skeptics want for documentary photographers.

Taggart, however, refuses such classification. "Purely as an artist, going through all the development courses with the spiritualists opened me up immensely," she said. "I could not wrap my brain around how you could be a sane person and talk to dead people." At the same time, however, she didn't enter this new world with an intent to debunk. "I didn't not believe," she said. Whether her images are of ghosts or frauds or camera errors doesn't matter much to Taggart — what counts isn't the exterior world they capture, but the interior world they provoke.

"When I first got interested in photography, it was through the work of Diane Arbus," Taggart said, referencing the famous photographer of twins, giants and dwarfs. "The first time I saw a Diane Arbus image, I was 16 years old and seeing her work, I was like, 'Oh, I get – you can put your thoughts into a picture.' I felt like I was seeing into her mind in some way, through her images."

It's this occult perspective she tries to capture in her images of spirit visitation. "It's impossible to photograph this stuff conventionally because the interior element is so huge," she said. "It's unphotographable." Nonetheless, lengthening exposures and allowing other products of "accident and error," into the work allowed Taggart to photograph it. "I'm not really looking for proof," she said. "I'm looking to go deep into the experience." Think of Garforth and the big hand — whatever explanation you prefer, Taggart's images capture her experience precisely. I found them deeply unnerving.

This artistic approach makes Taggart an enigma to skeptics and spiritualists alike. According to her, trusting photography to either prove or disprove the existence of spirits — or anything else, for that matter —is wrongheaded. "Photography is much too complicated of a medium," she said. "It's a trickster medium. It can be two things at once. That's what I love about it." For her, deliberate distortions "give your mind, or the photographic mechanism, something to play with." They invite interpretation.

At the beginning of her work in Lily Dale, Taggart photographed a woman named Dorothy. "A lovely lady, working in the museum," she recalled. "She was so helpful to me and showed me all around the museum. She was the first person who told me about spirit photography," the tradition of spirit photographs dating to the earliest days of the medium. "So," Taggart continued. "I took some pictures of her. One inside the museum and one when she was outside."

"There was a huge purple orb right on her right shoulder, in both pictures," she said. "Just for kicks I brought the picture back to Dorothy. She held it in her hand and said, 'Oh, that's Bob.'"

"Bob?" I asked.

"Bob was her deceased husband," Taggart explained. "A week later, I was walking around the town and she drove by me and I heard her telling people, 'that's the girl who photographed Bob in the museum.'" Taggart smiled. "I love seeing that as the point where my camera started showing me things – handing me a language to refer to the immaterial." For Taggart, the images were flawed and forgettable. For Dorothy, however, they had become thick with meaning. A purple splotch had soaked up all her memory and faith and knowledge of the world to come. Who am I, Taggart thought, to get in the way of that?

Shortly afterward, she recalled photographing another medium who, like Garforth, operates under a dim red light, necessitating a long exposure. In the séance, "everyone was saying, 'Oh, I see a woman who looks just like you right next to you, I think it's your grandmother.' And then other people were saying, 'She looks like you, but it's not you,'" and so on. Taggart didn't see anything.

Later, developing images from the session, a perfect duplicate of the medium's face appeared, connected by a thin, night-highway line of red to the original. Taggart recalls her excitement at the find. "Isn't that funny? Isn't that weird? Isn't that coincidental?" she asked. It was a distortion produced by motion and the long exposure, sure — but it was something else, too. Since then, Shannon has maintained her photographs' two faces in parallel. Artistically speaking, it's paid dividends. Some of her most arresting images will see print this month in the first Morbid Anatomy Anthology . Her lectures on the topic are in high demand.

"It must be hard to find other interesting subjects," I observed. "After all that. What could be as ambiguous as life, death and haunting?"

Taggart thought for a moment. "Well," she said, "I've been working on a book about Michael Jackson."
