Folio ILight

Everything the light touched turned blue. Everything that stood in its way, we kept.

Kyanos takes its name from κυανός, the Greek for a deep blue. We are a sun-printing studio above the harbour on Hydra, making cyanotypes the way they were first made in 1842 — iron salts, cotton paper, a quarter of an hour of Aegean sun — and we keep every plate we have ever exposed.

There is no lens and no retouching. A leaf lies on the paper, the sun does the rest, and water decides what stays.

  1. 1842

    Sir John Herschel finds that iron salts, left in sunlight, turn a lasting Prussian blue.

  2. 1843

    Anna Atkins lays seaweed on sensitised paper and makes the first book illustrated with photographs.

  3. 2014

    Kyanos opens a room above the harbour and pegs its first plate to the line.

Folio IIProcess

Five steps, one sun.

I · Coat Pl. 1205 — on the table now
  1. Coat

    Ferric ammonium citrate and potassium ferricyanide, mixed one to one under a dim bulb and brushed onto cotton rag in two crossing coats. The sheet dries in the dark.

    25 % + 10 % · two coats · 30 min in the dark

  2. Compose

    Specimens are laid face down and pressed under glass. Whatever is opaque will print white; whatever lets light through prints a shade in between.

    4 mm float glass · a contact print, no lens

  3. Expose

    Out into the sun. The yellow-green coat greys toward slate, then bronze at the edges. We read the colour, not the clock.

    8–20 min · UV index 7 or more

  4. Wash

    Running water carries off the iron that never saw light, and bare paper appears wherever the sun was blocked. A drop of hydrogen peroxide calls the blue up early.

    5 min running water · 3 % H₂O₂

  5. Dry

    The print hangs on the line for a day while the blue oxidises to its full depth. Nothing is retouched and nothing is thrown away.

    24 h on the line · then filed in the herbarium
