My college keeps hosting workshops for the students and this was one of the very interesting ones, the Cyanotype workshop. Even though I was not part of this workshop, I just loved the outcome. This composition of the results by each student stands distinct and attractive.
This college caught my interest and made me go back to YouTube and find out more about it. I was curious, how do they do it?
So basically, it's a chemical that will be spread on the paper or whatever bade you want to use, and then you put on it whatever you want to make like flowers, images, or any particular thing, then expose it to the sunlight for a while. What happens is, that the exposed chemically treated area will turn blue while the covered remains white based on the transparency and intensity of the light. Once the sun exposure is done remove everything from the top of it and rinse it with water to stop the process. As soon as you remove the top layer you will see the imprints of it on the base in different shades of blue to white. and after a waterwash, it gets more prominent. Dry it again and here you go, It's already with the outcome similar to these.
