	AlternativePhotography.com : the new cyanotype process
		The cyanotype process, also known as the blue print process was invented by Sir John Herschel in 1842 and is still performed today by many darkroom enthusiasts.
		The 'traditional' cyanotype recipe, invented by Sir John Herschel in 1842, has the merits of being cheap, easy, and substantially non-toxic.
		Cyanotypes so toned are able to withstand quite an alkaline environment without any image loss; this could prove useful if a buffered board was used to display the print and could even allow the subsequent use of other toning agents with an alkali content.

	Cyanotype
		Early on, the brown form of ferric ammonium citrate was used, but today the green form is used exclusively as it is more sensitive and produces a longer tonal scale.
		Most of the ferric non-silver processes, other than cyanotype, have fallen out of use, but I provide them here in case anyone should wish to experiment with them.
		Cyanotypes must have an acidic environment, or they will fade, so they are generally mounted on non-buffered mount board.

	Cyanotype - color it blue. (19th century photographic process offers creative photographic printing alternatives) - ...
		Cyanotype was a common experimental photographic process through the 1850's, and for a period there were even commercial iron papers.
		By the mid 1870's, however, the silver process we know today had matured to the point where Cyanotype was no longer used for photographic objectives, but it remained a viable process for reproducing technical drawings until the diazo process became available in the 1950's.
		Cyanotype is a slow contact printing process, and as such, requires negatives the size of the final print.

	Linda Treash Photography - Cyanotypes
		Cyanotype is an alternative photographic technique, first developed and widely used in the mid-19th Century.
		With their unusual Prussian blue tonal range, cyanotypes cannot be created by using a darkroom and enlarger, but must be contact printed in ultraviolet light.
		Today, the cyanotype is one of the many alternative process photographic techniques available to experimental art photographers.

	Cyanotype Rex - f295: The Art of Lensless Imaging
		Cyanotype is created by mixing ferric ammonium citrate and potassium ferricyanide solutions, and coating paper (or fabric) with the result.
		I expect those who rediscovered this form of cyanotype are trying to preserve their ability to collect money for workshops, at least for a while.
		Of course, using the same chemicals in similar quantity means Cyanotype Rex prints can be made for pennies per sheet, not counting the paper cost; if you buy the two basic chemicals in bulk and have access to a suitable sized paper at reasonable cost, it might well cost less than even discount enlarging paper.

	Photogram Images in the 1800s - Hippolyte Bayard, Schultze, Talbot, Anna Atkins, Sir John Herschel, Anne Dixon, Wilhelm ...
		Herschel was to use the photomechanical aspect of the cyanotype method to make copies of his notes, purely a practical use, however, his photograms of natural objects reflect the positioning of natural objects to form an artistic image.
		The cyanotype became an important and popular method for producing images during the 19th and 20th centuries because of the ease of coating the paper with photosensitive solution and because the image can be developed using water.
		The cyanotype process is a negative-acting process producing white lines on a blue background, Because of it's main application in the engineering and architectural fields it is commonly referred to as the blue-print process.

		Cyanotype was used by Anna Atkins to produce her study of British algae and botanical specimens, producing the first photographically illustrated book.
		The two cyanotype solutions, one of ferric ammonium citrate and the other of potassium ferricyanide, are mixed in equal proportions immediately before applying the emulsion to a paper or fabric receptor.
		The solution may be applied with a sponge, brush or glass coating rod, or in the case of fabric, the receptor may be fully immersed in the cyanotype solution.

	The Cyanotype Process
		The cyanotype process was one of the first non-silver technologies used to create photographic images.
		Originated in the 1840's, it was not utilized in mainstream photography and was adopted as a copying technique, becoming known by the term "blueprint", with its blue background reproductions of large architectural and mechanical drawings.
		Cyanotype is a negative process - areas where light does not hit sensitized material will remain white.

	AlternativePhotography.com : the cyanotype process
		The dried material can also be kept for longer periods of time, but some oxidation may occur and the final print will be dark blue on lighter blue, rather than blue on white (if white material is used).
		Cyanotypes are sensitive to alkine conditions, so buffered papers should be avoided.
		Cyanotypes or blueprinting is a very simple process.

	Freestyle Photographic Supplies - Teacher's Lounge
		The Cyanotype, which is also known as ferroprussiate or blueprint was invented by Sir John Herschel in 1842, when he discovered that ferric (iron) salts could be reduced to a ferrous state by light and then combined with other salts to create a blue-and-white image.
		A cyanotype with a blue image on a white background is obtained using a negative transparency.
		The cyanotype emulsion is sensitive to ultraviolet light.

		Cyanotype is an old monochrome photographic printing process that gives a cyan-blue print.
		Though Herschel is perhaps the inventor of the cyanotype process, it was Anna Atkins, a British scientist, who brought the process into the realm of photography.
		Another unusual characteristic of the cyanotype is its regenerative behaviour: prints that have faded due to prolonged exposure to light can often be significantly restored to their original tone by simply temporarily storing them in a dark environment.

	A. D. White Photographs, The Cyanotype
		Sir John Herschel invented the cyanotype process in 1842, rather early in the history of photography.
		Cyanotype prints have no emulsion; the light-sensitive iron salts have been infused into the paper fibers, unlike either albumen or gelatin silver prints.
		Cyanotypes were far simpler and les expensive to produce, which made them a favorite method for turn-of-the-century amateurs who wanted to make proofs of their negatives.

	The Cyanotype
		The Cyanotype, or blue print process, was invented by Sir John Herschel in 1842, thus making it one of the very earliest photographic processes.
		The best known early proponent of cyanotypes was Anna Atkins who did a series of leaf prints and also published books utilizing the process.
		Another example of its utility can be seen in the cyanotypes of the building of the Boston Elevated Railway Line, some of which are featured in New This Month.

	Mike Ware - The New Cyanotype Process
		If the growing number of cyanotypes now to be seen on gallery walls and in published commercial work (4) is anything to go by, the process is also providing a significant number of contemporary photographic artists with an expressive medium in its own right, in spite of (or maybe because of) its rather strident colour.
		Disadvantages (4) and (5) are due to the fact, already stated, that the cyanotype process produces the so-called "soluble" form of Prussian Blue.
		Whether the light source is the sun or a UV lamp, exposure is much shorter than that needed for the traditional Cyanotype recipes - this new sensitizer requires about two to four minutes exposure under an average light source.

	Blueprint to Cyanotype - An Interview with Malin Fabbri
		In 2000 I received an e-mail from Malin Hylen, who was writing a paper on the 19th Century cyanotype printing process as a thesis for her MA Degree in Design Studies from Central St. Martin's School of Design in London, England.
		In the end I didn't use cyanotypes in the magazine, but the coincidence led to a Master's thesis in "alternative photography." I started a website, "Cyanotypes.com," which evolved into "AlternativePhotography.com", and that's where we are today - the site is packed with practical information and over 200 artists have galleries on the site.
		Besides the many wonderful examples of cyanotype pirnts from photographers in many parts of the world, the book also offers information on the history of the cyanotype as well as step-by-step instruction on how to mix chemicals, coat paper and print cyanotypes along “how-to” photographs.

	Cyanotype Project
		In this process, a suitable (both chemically and physically) sheet of paper is made sensitive to high energy ultra violet (UV) light by coating it with a solution of ferric ammonium citrate and potassium ferricyanide.
		The image intensifies upon drying as ferrous ferrocyanide is slowly oxidized to a deep blue color that results from a mixture of ferric ferrocyanide and ferric ferricyanide.
		An ideal paper for cyanotype printing should be somewhat hydrophobic, so that it does not fall apart during the rinsing process, but it should not be too hydrophobic, since very hydrophobic paper will not absorb the coating.

		As they report, the fundamental chemistry in the cyanotype process begins when exposure of ferric ammonium citrate to UV light causes the photoreduction of Fe(III) to Fe(II); the citrate counterion furnishes the electrons for the reduction.
		The chemical reactions taking place in the cyanotype process are not well understood, beginning with the uncertain structure for ferric ammonium citrate.
		From this I speculate that the photoactive compound in the cyanotype process is a dinuclear complex of the same sort responsible for the solution photochemistry.
