Cyanotype is one of the oldest nonsilver monochromatic processes. It is based on the sensitivity of iron salts and gives images of a characteristic blue.<\/span><\/p>\n

Historical period of production and use<\/span><\/p>\n

Invented in 1842 by John Frederick Herschel, an English scientist, the cyanotype was a late success: its deep, intense blue and painterly rendering did not seduce photographers of the time who sought a more realistic rendering. Its use is therefore essentially documentary, reserved for the reproduction of notes, architectural plans or industrial drawings. Mention must be made of two photographers who were particularly seduced by its properties in the 1840s-18401850: the English botanist Anna Atkins for her plant stills and the French artist Henri Le Secq for his work on Parisian Gothic monuments and still lifes. The process did not become popular until the late 19th century. It was appreciated by painters, Paul Burty Haviland in the lead, who showed keen interest in its aesthetic qualities.Today,cyanotype is used by many contemporary artists such as Nancy Wilson Pajic, who contributed to its revival.<\/span><\/p>\n

Manufacture<\/span><\/p>\n

Based on the sensitivity of iron salts to light, its implementation is relatively simple, fast and inexpensive. The paper is sensitized with a solution of ammonium iron citrate and potassium ferricyanide and should dry in the dark. The printing then takes place by contact with light The time of exposure to natural light can last up to fifteen minutes depending on the brightness, producing a change in the composition of the iron salts. The paper is then rinsed with water to dissolve unexposed iron salts and then dried. It is during this operation that the characteristic Prussian blue color characteristic of the process is formed.<\/span><\/p>\n

Botanical cyanotype<\/span><\/p>\n

This process is fascinating because it appeals to creativity, invites experimentation and allows us to be attentive to the small details of nature throughout the seasons. Since I do cyanotypes, I am always looking for something to collect, and my walks in Sardinia, turn into a treasure hunt. My collection of tree leaves and feathers has grown! I also like the fact that the process is created with sunlight, I find it adds a bit of magic and invites even more connection with nature.<\/span><\/p>\n
