The Cyanotype Process
Cyanotype is a photographic imaging process that uses UV light to contrast negative and positive space. When the cyanotype is exposed to light, any space hit by the light is turned blue, while the positive space is turned to white.To make our drawings appear on the cyanotype paper, we place the tracing paper with our drawing on top of the cyanotype and leave it exposed to the sun.

Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention if irritation occurs. Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops. Cold water may be used. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention. Ingestion: Do NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. If large quantities of this material are swallowed, call a physician immediately. Loosen tight clothing such as a collar, tie, belt or waistband. |

Reflection Questions

1. The cyanotype emulsion when applied to the paper was a greenish yellow
2.When it was placed in sunlight, the emulsion turned blue because the iron reacts with the ferryicyanide to turn the paper blue. 3. When the glass and objects were removed, the space where my drawing was, was lighter than the other areas. 4. The exposed areas of the print were dark blue while the unexposed areas turned completely white. I think that when placed in water it made the blue darker and the light areas white because it washes away The water-soluble iron(III) salts are, while the non-water-soluble Prussian blue remains in the paper. 5. The process was very cool and fascinating and I would like to do it again maybe with a more complex object or drawing. |
