My first alternative photogaphy love is cyanotype. So to expand my practice I decided to attempt to tone a set I did of the bluebells from my garden. Was all pretty low tech, using tea, coffee and vinger. Love the results – but they did not tone as much as I would have liked – I used very cheap water colour paper which was not very robust. Will try again with more substantial paper.
The first attempt was just bleaching (50ml in 1L of water) the image.

I then used a strong solution of tea – 5 tea bags in 1L of water. I left the image in the tea for about 30 min.

I kept with the beveridge theme – had a go with coffee (5 large spoons in 1L water)

I then used sodium carbonate ( a pinch in 1L of water)

I then doubled up, bleach then coffee.

I then tried to use coffee and vinger – moving between each bath after a few seconds – it was supposed to be for 10min – but the paper (cheap!!) fell apart after about 5min.

The most success and my favorite images are when I soaked the paper in tea overnight. Love the depth of colour.
