Cyanotype Process

We tried to types of cyanotype processing. One was using bought cyanotype paper and the other was painting the emulsion on yourself, both worked, however painting on the emulsion yourself took longer, but the result was worth it.

When using the cyanotype paper you either used your transparency prepared earlier or found objects, absolutely anything could be used. I used doilies and flowers. Once you have placed your objects where you want them to be you cover it with black plastic and head outside into the sun, it's ideal if it's a sunny day with high UV, because the UV rays is what develops the cyanotype.

If you are painting on the emulsion yourself, you had to use a glass rod and carefully drag the rod down the page, after having applied the liquid cyanotype chemical infront/underneath the rod with a small dropper. After the chemical has been layered up and enough has been applied to the paper the glass rod is washed and dried thoroughly and the paper is to be dried on the back side of it, with a hairdryer. 

The process of painting on the cyanotype chemical can turn out with a few smears and drops, however this looks more authentic and is part of the process.
