Photography is a time machine - it makes recordings of light at a moment frozen in time and space. Looking at a photograph transports you back to a place where you see a resemblance of what the photographer saw when the picture was made.
The photographs in Spectral Visions are recorded in infrared light, a part of the light spectrum not visible to humans. Just like visible-light photographs, these images are recordings of a frozen moment. But unlike normal photography, the representations here were unseen when the images were made; they are only visible as photographs.
