Cyanotypes and Salt Printing Workshop

On Thursday 5th June 2014, to conclude my second year at university, I took part in a Cyanotypes and Salt Printing Workshop. Throughout the day, we were taught the method of each of these processes and were able to experiment with creating our own prints. Below you will find hand-out sheets that we were given for each process, along with some extra notes that I made, the scans of my experimental pieces, and some photos from the day:

CYANOTYPES:

Cyanotype Hand Out

  • Most accessible and least expensive – only two materials
  • Good to teach to children as it is very safe
  • Can do it on other materials – for example, cotton
  • Has been suggested that we can use bicarbonate of soda in order to intensify the colour of the cyanotype
  • Alexander Hamilton “Four Flowers – his cyanotypes have a deep blue (almost black) in the centre of the image that works its way out to being a typical cyanotype blue around the edges; suggested that he used Hydrogen Peroxide in the rinse bath to make the more intense colours; bleach can work too but need to be careful about stains

Scan

This Cyanotype is sightly over-exposed due to the loss of detail in the flowers petals.

Scan 4

Although correctly exposed, the paper that I used for this cyanotype has created a grainy effect.

 

SALT PRINTING:

Salt Printing Hand Out

  • Very labour intensive
  • Silver nitrate is very expensive
  • The salt in the mixture must not have any additives

Scan 2

This salt print is very under-exposed due to the lacking of both colour and detail.

Scan 3

This salt print seems only slightly under-exposed.

Scan 1

This salt print is only slightly over-exposed, and due to the difference in exposure of the two negatives, their exposure varies.
