Poplar Leaves Cyanotype Print

Cyanotype is an early photographic printing process that produces a cyan-blue print (it's where the term 'blueprint' comes from).

The process uses two chemicals: ammonium iron(III) citrate and potassium ferricyanide, applied (in my case painted) onto paper, dried (in the dark) and then exposed to sunlight with the object placed directly onto the coated paper.

In this case fallen leaves from a Poplar tree were placed onto Khadi 100% cotton rag handmade acid free paper and exposed to the sun, washed and dried.

Every cyanotype is unique.

Paper size is approx 21 x 21cm
