How To Create Cyanotypes – A Step By Step Guide
How To Create Cyanotypes
Cyanotypes are one of the oldest photographic techniques used today. Introduced by Sir John Hershel in 1842 and unlike photographs which are set in silver, Cyanotypes are using a solution of iron compound. When created Cyanotypes had the advantage of less bleed on the paper a lower exposure time although the chemical mix was more complicated. The Cyanotype process is a simple one and when the Cyanotype chemical is exposed to UV light it will darken.
Cyanotype mixture is mixed in the following way:
- Potassium ferricyanide and Ferric ammonium citrate get mixed separately with water.
- The two solutions are then mixed together in equal parts and this makes the final Cyanotype solution.
Some other equipment you will need::
- Measuring jug
- Glass containers
- Face mask
- Paper or similar to cover working surfaces
- A cloth
- UV Light source
- Fresh water from a tap preferably
Once the Cyanotype mixture has been created, the process to make an image is very simple:Box large
•Put on your apron and any other personal protective equipment (PPE)
- Firstly in a darkened area coat a piece of paper, cloth, card or any other material that absorbs fluids.
- Next place a negative or object onto your treated material and expose to any UV light source – The most common is the sun.
- Once the desired image has been created rinse the material under water which stops the UV process
- Finally allow to dry and you will have the desired image.
That’s it you are done, enjoy your blue cyanotype image and check out the rest of my blog for more alternative photography technques.Box large
