Back in June, I took a Soil Chromatography workshop hosted by the Land Art Collective and lead by Hannah Fletcher. Soil chromatography is a photographic process. Finely ground soil is absorbed by filter paper that has been prepared with a weak silver nitrate solution, and thanks to capillary action and exposure to light , a ‘picture’ of that soil appears.
Have been experimenting with printing cyanotype on stones. Two coats of cyanotype solution and a 13 minute exposure using a digital negative seems to be working well.
I have been experimenting with eco printing the last few weeks. In eco printing , plants are placed between sheets of watercolor paper, stacked and bound in layers and then simmered in hot water to extract the pigments and produce a print made with the plant dyes. Not all leaves produce good prints and I have had good success with oak, willow and rose leaves.
