Sunprinting was originally developed as a teaching tool by educators at the Lawrence Hall of Science on the UC Berkeley campus. It is based on the cyanotype process, which has been used by artists since its development in the 19th century.
Objects that eclipse the sun's light will show up in white, with the rest of the paper turning a vibrant Prussian Blue. Gradients between these two ends are easy to achieve. Make prints of physical objects or transfer digital images via transparency sheet.
This is a great way to get kids interested in the science behind photography. You may also like to try the Sunprint Super kit, which is similar to this kit. The Super kit has larger sheets (20x30cm vs 10x10cm) and have 3 additional sheets.
How you can make your own Sunprints
- You will need : Sunprint kit, cardboard, a tub full of water, fun and interesting objects to print
- Arrange your objects on a piece of Sunprint paper (blue side up) out of the reach of the sun, with cardboard on the bottom. Note, even ambient light in the shade, or in a room with a big window will cause slow exposure of the paper.
- Place the acrylic pressing sheet on top to flatten and hold your items to the Sunprint paper.
- Take your Sunprint outside and lay it in direct sunlight for 1-5 minutes, depending on the sunlight. Do not overexpose.
- Rinse your Sunprint in water. Watch the white turn into blue and the blue turn into white.
- Lay your Sunprint flat on an absorbent surface and allow it to dry.
Did you know Sunprint paper can be used as a scientific tool? It can be used as a measuring tool for any other UV light source, or as a photographic medium to use in scientific experiements.
