Cyanotype paper allows you to reproduce notes or diagrams in blue print. It has been in use since 1842 when Herschel developed it. It uses the action of light to create the silhouette effect. This process has been in use over years before the discovery of color photography. It does not require the use of camera to produce images and the resulting images are always blue.
It is a fun filled process creating images through a manual and natural process. This makes it interesting and rewarding considering that you will not require any machine. Caution must however be exercised to prevent blurring the images or distorting them. The surface is coated using a special chemical substance before exposure to UV light.
You have the option of using either the object or its negative in order to generate the image. The solution applied requires washing to reveal the image. Using the same negative or image means that you will achieve uniformity. It is this technology that was used before photography became common and was used in mass production.
The choice of water color papers to use should be informed by their features. The outcome can be jeopardized by coated papers that react with the coating chemical. Uncoated and non acidic papers are preferred. Natural textile is another alternative instead of using synthetic material. The natural selection produces incredible results.
The process of mixing and coating involves substances with toxic elements. This therefore demands the use of protective cloths like masks, gloves and goggles. They protect your skin from damage by the chemicals you are handling. The market has provided premixed solutions which favor small scale uses. Mixing the ingredients on your own makes the process easier and economical for large scale operators.
The two chemicals mixed in the process are ammonium citrate and potassium ferricyanide. Instructions should be followed if desired results are to be obtained. They are mixed in equal quantities and used almost immediately. The solution does not have a long effective shelf life. Keeping it for a while will affect its effectiveness.
The process only works when the surface is exposed to UV light. This gives you perfect working conditions at night without worrying about protective lighting. The paper is coated and dried in a very dark place to make it more sensitive to the light.
You have the option of using the image or its negative to generate the image. The actual object becomes challenging at times considering the expected sizes of some of them. This makes the option of a negative more viable because it is easy to fit any image on a piece of paper. You are required to rinse the paper to get rid of the chemical and allow iodizing to be completed.
Images produced with the cyanotype paper are thoroughly cleaned of the chemical before drying. Ensure that the cleaning process does not make the images fade away. It should be done in moderation to avoid damaging the images. The final product is hung in the sun to dry or placed on a flat surface. It is the natural light that will trace your image on the surface.
