The cyanotype paper is light sensitive, so only take it out when you are ready to start using it, and protect the remaining sheets from light. When exposing your composition to light, watch the paper slowly change from blue to almost white. This should take around 3-5 minutes in full sun but longer if it is cloudy.
How do you prepare cyanotype paper?

How does cyanotype paper work?
Cyanotype is a magical form of photography, or light printing, whereby a light-sensitive chemical wash is applied to paper, and objects or a photo negative are placed on the paper which is then exposed to sunlight.
How long do you expose a cyanotype?
On average exposure time is about 10-20 minutes. Expose your print until the highlight values seem darker than you prefer. The highlights will come back in the wash.
Does cyanotype have to be dry?
Cyanotypes must be over-exposed to create a permanent image An exposed image that appears faded and “washed out” will darken to a deep blue color after wet processing. Judging the proper time to remove the print from the light is the most crucial part of the Cyanotype process.
How do you know when a cyanotype is done?
Exposing the Cyanotype When your coated and sensitized paper or fabric is completely dry, place your negative in contact with the coated emulsion and double check to see that it will read correctly when it is completed.
Can you use normal paper for cyanotype?
Light or thin papers disintegrate during the washing stage, so regular bond paper, for example, doesn’t work. The lowest weight I’ve used for cyanotype is 90 gsm (grams per square meter, which is a universal standard for paper weight). You can undoubtedly use tissue-thin papers like Japanese washi and parchment.
What paper can you use for cyanotype?
Papers to use for cyanotypes Light blue platine mud. Winsor and Newton cartridge paper. Dark blue platine mud. Winsor and Newton cartridge paper. Canson Montval. Daler Rowney cartridge paper (2 days later) Winsor and Newton Cartridge paper. Canson Montval Watercolour paper.
How do you fix cyanotype?
The cyanotype paper must be totally dry before you use it, or else it will develop as it is exposed. There is no “fixer” as such; the blue is ferric ferrocyanide, which is permanently bound to the paper. Wash properly and let dry, and it will pretty well be blue forever.
Is cyanotype a photograph?
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.
Do cyanotypes work when its cloudy?
You don’t need a hot sunny day to make cyanotypes. Even on a cloudy day there will be enough UV for an exposure.
Can you do cyanotype indoors?
You will also need a UV light source for exposing cyanotypes indoors. You can use the sun as your UV light source, but in my experience, it’s challenging to have a consistent process using sunlight because it depends on the time of day and extent of cloud cover.
Are cyanotypes always blue?
An unadulterated cyanotype will always be blue. However, there are many methods for toning finished cyanotype prints to other colors using household materials like tea, coffee and soap. Cyanotypes can be toned to a variety of browns, blacks, yellows and more.
How long should you wash cyanotype?
Wash for at least 5 minutes, changing the water periodically, until the water runs clear. Do not use soap. With wetting, the print will change from a bronze to blue color. To instantly process prints to the final deep blue color, submerge washed prints in a dilute solution of hydrogen peroxide, then rinse.
How long does cyanotype paper take to dry?
Let the paper dry flat for at least 1 hour, preferably 2 in a dark room. No lights. After the paper is bone dry (don’t touch the emulsion!) put it in a light safe bag overnight.
Why is my cyanotype green?
The first coat will have gone green (the bits where there has been no second coat applied) because during the exposure it will collect a lot more light than the bits that were double-coated. Green is a good indicator for proper exposure.
Can you cyanotype on wood?
The only problem you may have is that the wood has some iron parts which will interact directly with the cyanotype mixture. the faster the complete process takes place, the less problem with iron parts you will have. example of liquid light emulsion on wood.
What is a wet cyanotype?
The process starts out the same as normal cyanotype: coating the paper with cyanotype solution in a darkroom environment (or at least a room with heavy curtains/blinds pulled shut). After the cyanotype paper has dried, the fun begins.
Can you cyanotype a shirt?
For cyanotypes, you don’t need a room that is completely light safe – just mostly. Cover up anything you don’t want to turn blue. You can do everything by Christmas tree lights without exposing your cyanotypes. Prepare a place to hang the wet shirts so they can dry overnight without touching anything.
What materials do you need for cyanotype?
Materials Cyanotype kit (Potassium ferricyanide + Ferric ammonium citrate) Large disposable cup or plastic bowl. 1 yard of 100% cotton fabric. Leafs, plants, or other flat objects. Rubber gloves. Hydrogen peroxide (optional).
How do you make a paper SunPrint?
Collect a selection of leaves and flowers. Arrange your plants on the construction paper according to your artistic tastes. Use thin strips of tape to secure your plants on the paper. Tape your paper onto a window, with the plants facing outwards. Leave the paper in the Sun for a few hours.
How did Anna Atkins make Cyanotypes?
Sir John Herschel, a friend of Atkins and Children, invented the cyanotype photographic process in 1842. Within a year, Atkins applied the process to algae (specifically, seaweed) by making cyanotype photograms that were contact printed “by placing the unmounted dried-algae original directly on the cyanotype paper”.
