Cyanotype is an ancient printing technique widely used in the production technical drawings (blueprint) crafts, and artworks. It is also known as the sun print and was the first practical non-silver photographic process to emerge after the invention of photography. The cyanotype process is safe, which is one of its major advantages. The developing agent used in cyanotype is water, and the photosensitive agent consists of only two components: ammonium iron citrate and potassium ferricyanide. During the production process, these two liquids are mixed together in a 1:1 ratio to form a photosensitive coating that can be applied over a large area. Next, a negative film or real object is placed on the paper coated with the photosensitive solution and processed under exposure to ultraviolet light. Finally, the unexposed parts without the photosynthesis reaction are rinsed off, revealing an image with a photographic quality.
By participating in the "Photography and Cyanotype" course, students will have the opportunity to explore various visual expression methods and showcase their unique creativity and ideas through photography and cyanotype. This course will provide valuable hands-on experience for students, regardless of their interest in photography or cyanotype. Through practice, students will gradually enhance their photography, graphic design and cyanotype skills, as well as their understanding and ability to express themselves in artistic creation.
