Cyanotype experimentation with final piece

The cyanotype is a process making a photograph with a blue, died effect which can be printed on fabric, paper, wood etc. This process is made up of two simple solutions.
  • Potassium ferricyanide and Ferric ammonium citrate (green) are mixed with water separately.
  • The two solutions are then blended together in equal parts.
  • Paper, card, textiles or any other naturally absorbent material is coated with the solution and dried in the dark.
  • Using Photoshop edit the image to negative if you want it positive, vise versa and then print. The cyanotype is printed using UV light, such as the sun, a light box or a UV lamp.
  • After exposure of 15/20 minutes the material is processed by simply rinsing it in water. A white print emerges on a blue background.
  • The final print is dried and ready!
The process didn't work very well as shown here:

     
     
    It firstly started off unsuccesfully as I hadn't contrasted the inverted picture enough, so I went back again and changed the levels on Photoshop so it would become successful. I over exposed it too much outside which meant it was unsuccessful again so I went into the dark room to do some photograms to make sure my inverted picture was fine. Here it is:
     

     
     
    Learning from this I can see that I need to make the dark parts of the image even darker and brighten some parts using Levels again on Photoshop.
