Today, I tried my first cyanotype print! Interesting!
Cyanotype is a photographic printing process that gives a cyan-blue print. The process was popular in engineering circles well into the 20th century. The simple and low-cost process enabled them to produce large-scale copies of their work, referred to as blueprints. Two chemicals are used in the process:
* Ammonium iron(III) citrate
* Potassium ferricyanide.
I have to do the printing process on a dark room because it exposure to ultraviolet light (such as that in sunlight). I mixed the two chemicals carefully, painted it on a watercolor paper. After the paper is dry, I put some stencil on the top of the paper. Then, bring it outside under sun light. After 1 to 2 hours, I bring them back and wash away the chemicals. Wait until them dry and finish! The whole process spent me about 7 hours, I did the two on the left. As you see, they are fail work compare to my friend's... wish I will make it better when I have more time.

Photography as art is a very serious job. You did good job!!! I like you works.
Thank you, I agree that photograph takes more serious, When people take photos, they need to think more about things like the light and angle.
A loooong time ago when I studied photography, I spent quite some time working with cyanotype. Love it!
