Alternative Process: Cyanotype

Final Cyanotype Plan:

Materials List:

  • 25 grams Ferric ammonium citrate
  • 10 grams Potassium ferricyanide
  • 3 Glass containers 
  • Graduated cylinder for measuring
  • Plastic spoons
  • Gloves
  • Scale (for measuring chemicals)
  • Paint brush
  • (Mostly) Cotton paper or fabric to print on
  • Glass to cover cyanotype  



Cyanotypes are done by the following process :

  1. Create a negative image of a  photograph and print it out on a transparent paper.
  2. Mix the chemical solution to be brushed onto the cotton paper. The chemicals are mixed together in equal parts.
    1. 25 grams Ferric ammonium citrate (green) and 100 ml. water
    2. 10 grams Potassium ferricyanide and 100 ml. water.
  3. In a really dimly lit or dark room, brush the chemical solution onto the paper with a brush and leave it in total darkness to dry.
  4. Place the negative on top of the paper and place a piece of glass over that to hold it together.
  5. Expose the cyanotype to light (either the sun or a UV light) 
  6. After it has been exposed, rinse the print in cold water until the water runs clear.


I will print two images onto pieces of fabric using this process. One will be larger and the other small. I will then wait until the fabric dries and stretch and staple the first image over a wooden frame that I have. The other image will be stretched over the smaller piece of wood. Then, I will attach the smaller canvas onto the top of the larger image.
