Amagansett - Having taken pictures for over 40 years, photographer Diane Tuft published her first book "Unseen" this month, which she was on hand to sign at Sylvester & Co. At Home in Amagansett this weekend. While "Unseen" might seem a strange, almost paradoxical appraoch to title a book of photography, the names comes not from what the photos are of themselves, but rather the manner in which they were taken.

"The book is called "Unseen" because it's all landscape photography that is based on light that you cannot see," Tuft said at the signing. "Outside of the light waves we can normally see there are light waves that are longer infrared light waves and there are shorter ultraviolet waves. All of the black and white photos in the book are done with infrared film and all of the color photographs are done in locations were there is a lot of ultraviolet light."

By visiting places like the Great Salt Lake, a place where there is a higher level of ultraviolet light because it sits at 8,000 feet above sea level and taking pictures that capture this frequency of light wave, Tuft is able to create an interesting, almost abstract effect. "The intensity of the color is much greater than what we can actually see because the ultraviolet light is reflected in the camera," she said.

"Salt Lake 1" is one of the images Tuft took at the Great Salt Lake, an area with a high level of ultraviolet light, normally invisible to the naked eye.

On the other end of the spectrum, literally, the images she took using infrared film, are likewise able to capture colors and reflections that are otherwise invisible to the naked eye. "The infrared film captures those wavelengths that are actually reflecting the heat that is on the landscape so if something is a little closer to the sun it might be a little lighter and something a little darker would be further from the sun, which makes the shadows very dark and something that is a highlight becomes very bright. Also, because infrared waves go through certain objects like water and hit another object and reflect back, it creates a very surrealistic approach to photography."

Tuft explained that this concept of photography stems from her background in two somewhat different, yet occasionally overlapping fields, coupled with a natural intrigue about the world around her. "I have a science background and also an art background so I'm just always very curious and it just came from experimenting with the photographs I've been taking," she related. "I'm very excited about this book."
