Cyanotype Directions

Detailed Steps:1. Prepare the Chemicals:Mix equal parts of the two cyanotype solutions (ferric ammonium citrate and potassium ferricyanide) in a dark area. Only mix what you need immediately, as the solution is light-sensitive.

 

2. Coat the Paper or Fabric:Apply the mixed solution evenly to your chosen material using a brush, sponge, or coating rod. Ensure the coating is thin and even.

 

3. Dry in the Dark:Allow the coated material to dry completely in a dark, dry space. This prevents premature exposure to light.

 

4. Arrange and Expose:Place your negative (or objects for a photogram) on the coated material. Secure it with glass or a contact print frame. Expose it to strong UV light (sunlight or a UV lamp).

 

5. Expose Time:Exposure times vary depending on light strength and your desired effect, but a good starting point is 3-30 minutes in direct sunlight. The paper will turn from a light green/yellow to a darker green when exposed.

 

6. Rinse and Develop:Rinse the exposed print in cold water until the yellow stain (unexposed chemicals) is washed away. You can add a little hydrogen peroxide to the water to deepen the blue color.

 

7. Dry and Enjoy:Allow the print to dry completely, and your cyanotype is ready. Tips for Success:Work in a darkroom or dim light: Protect the chemicals and coated materials from light until they are fully exposed. Use fresh chemicals: Ensure the chemicals are not expired for best results. Experiment with exposure times: Different light conditions require different exposure times.

 

Consider toning or bleaching: Experiment with toning (e.g., tea) or bleaching (e.g., baking soda) to alter the print's color. Clean up thoroughly: Rinse all equipment and surfaces to prevent chemical residue.
