Cyanotype is an alternative photographic technique, first developed and widely used in the mid-19th Century. With their unusual Prussian blue tonal range, cyanotypes cannot be created by using a darkroom and enlarger, but must be contact printed in ultraviolet light. Ultimately, the process lost popularity due to the blue-only color of the emulsion. Today, the cyanotype is one of the many alternative process photographic techniques available to experimental art photographers.

For these prints, the artist hand-mixes the iron salt cyanotype sensitizer and brushes it onto an ultra-thin, 100% rag translucent paper. She layers the coated rag paper with an enlarged paper negative and presses them into a spring-loaded printing frame. The size of the resulting image is limited to the size of the negative, although an enlarged, inter-negative can be used to a limited degree. Outside in the vague and variable Vermont sunshine, the prints take 30 minutes to 4 hours to develop.

The cyanotype chemicals are the same chemicals originally used to copy architectural plans before copiers were available, thus the name "blueprints."
