When was the cyanotype process first used?

When was the cyanotype process first used?

1842
John Hershel’s cyanotype print ‘Lady with Harp’. The cyanotype process, also known as the blueprint process, was first introduced by John Herschel (1792 – 1871) in 1842. Sir John was an astronomer, trying to find a way of copying his notes. Herschel managed to fix pictures using hyposulphite of soda as early as 1839.

What was cyanotype printing first used for?

In 1842 Sir John Herschel came up with the process of cyanotyping as a cost effective means of reproducing notes and diagrams. A friend and colleague of his, Anna Atkins, later used the technique to produce the worlds first photographically illustrated book, Photographs of British Algae: Cyanotype Impressions.

What was the cyanotype printing process?

Cyanotype is a photographic printing process that produces a cyan-blue print. Engineers used the process well into the 20th century as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ferric ammonium citrate and potassium ferricyanide.

Who brought cyanotype printing to photography?

Sir John Herschel
Cyanotype (sa-YAN-no-type) is a photographic printing process invented in 1842 by Sir John Herschel—three years after the birth of photography. Its telltale characteristic is the heavenly blue color—a result of a chemical reaction when cyanotype is exposed to ultraviolet light.

What was Anna Atkins known for?

English botanical artist, collector and photographer Anna Atkins was the first person to illustrate a book with photographic images. Her nineteenth-century cyanotypes used light exposure and a simple chemical process to create impressively detailed blueprints of botanical specimens.

What type of print was derived from cyanotype?

The cyanotype is a photographic printing process that produces blue prints using coated paper and light. The process was discovered by the scientist and astronomer Sir John Herschel in 1842.

Are Cyanotypes still used today?

Cyanotypes are still used today as an alternative printing medium; however, during the 20th century, as photography and technology advanced, the technique became somewhat obsolete. It reverted to primarily being used for replicating architectural diagrams and design notes—aka blueprints.

Is cyanotype considered photography?

The cyanotype is a photographic printing process that produces blue prints using coated paper and light.

How do you make gum bichromate prints?

Equal parts of the gum and dichromate solution are mixed together with a small amount of watercolor pigment. Once mixed they should be applied to the paper within an hour. A little goes a long way. Add Pigment to the Emulsion: The pigment can be any color of watercolor paint that you choose.

How old are Cyanotypes?

170 year old
Cyanotype is a 170 year old photographic printing process that produces prints in a distinctive dark greenish-blue. The word cyan comes from the Greek, meaning “dark blue substance.” The process was invented by Sir John Herschel, a brilliant astronomer and scientist, in 1842.

When was the cyanotype first used?

The cyanotype process was seldom used until the 1880s, when it became a cheap proofing process for collodion, dry gelatin plates, and gelatin roll film before the final printing, which used more expensive silver- or platinum-based photographic processes.

What kind of paper should I use for my cyanotype print?

In general, if your negative will give a good print using grade 0 paper, it will give an excellent cyanotype print. Almost any porous surface can be used. If you are using paper we suggest that you use a sized but unsensitized or uncoated paper, such as watercolor paper, which we carry at Freestyle.

How do I Clean my cyanotype print?

Once the print has enough exposure, simply put it in a tray and rinse under running water for 10-12 minutes. Any unexposed chemicals will wash away, revealing a print of deep blue. The blue shadows will darken as the print dries, as will the highlights. Set your print aside to dry on a drying rack or clothes line, and your cyanotype is complete!

What is the difference between a negative and a cyanotype?

Cyanotypes are “contact prints,” meaning your print will be the same size as the negative you use. If you don’t shoot large format film (4×5, 8×10), then you will have to print a suitable negative onto transparency film ( find at Adorama) using an inkjet printer.
