Cyanotype is one of the earliest forms of photographic process, distinctive for its Prussian blue monochrome prints. It dates back to the mid-1800s and was later used as a simple and low-cost way for engineers to create copies of their drawing plans, hence the origin of the term ‘blueprint’. The process involves making contact prints with light-sensitive paper, either using photographic negatives, or photograms of objects and other materials. The process is easy to learn, ideal for experimentation, and can be done at home using daylight. Find out more about the workshop here.
