As beautiful as Cyanotypes are, the blue tone tends to overpower the image a little too much sometimes. Mr. Arpan Mukherjee’s workshop turned out to be just the thing I was looking for.
As a part of the extensive work he has done with Alternative methods of photography, his works with Cyanotype particularly caught my attention. He mentioned about using a natural seed called Haritaki for toning the images and giving it a beautiful coffee warm tone.
Following is the procedure we used for the toning:
We soaked the Haritaki seeds overnight and boiled them for 15 minutes.
A dry Cyanotype print was bleached first in the mixture of Potassium carbonate.
You can see the colour instantly changing and turning into a pleasing pale yellow.
Then the print is placed into a solution of Haritaki diluted in water.
After a while you see the color changing and turning into a warm brown.
The print later needs to be thoroughly washed and dried.
Following are the before and after images.
