Cyanotype Project

​What is a Cyanotype?
It is a photographic procedure discovered in 1842 by Sir John Herschel, an English Scientist and astronomer.  This process produces a cyan-blue print or sun printing, It is known as a photographic blueprint.
The process requires two chemicals: ammonium iron (III) citrate & potassium.

Steps: The Cyanotype Project 

For my light-based media class, we are experimenting with Cyanotypes to capture an image using natural light.......this is my experimental results

Step 1:

Placing objects on the Cyanotype paper....which I  then left exposed to natural sunlight.

Paper should be exposed to light for a minimum of 15 mins-30mins. The more it is exposed to a source of natural light the better! 


Step 2:
After waiting at least 30 minutes I removed the objects......and their shadows remained on the page.


Step 3:
After washing the paper with water in the sink,  I got this result.

Result:
The Silhouettes of the objects are shown on the chemically treated paper.

Note: I used pre-treated papers made specifically for cyanotypes.
