What the Light Remembers
The Sun as Engraver
Ferric ammonium citrate and potassium ferricyanide, brushed onto rag paper, need only daylight to begin their slow, irreversible work.
No Negative, No Edition
Every cyanotype is a one-to-one contact print. There is no intermediate plate, no mechanical reproduction between the specimen and the page.
Silhouettes Truer Than Ink
A pressed fern laid against sensitised paper records what no draughtsman’s hand can capture: every frond, every spore, the soft uncertainty at the leaf’s edge.
Prussian Blue Outlasts Us
Plates produced in 1843 remain as deep and legible as the afternoon they were rinsed in running water. Iron salts fixed by light do not fade.
