Procédé Transposition
Each Maison Picturale print is a material reinterpretation of the image. Three readings of the same work — the original, its closest transposition, and a creative transposition into another procédé.
Deep Prussian blue on 640 gsm cotton paper. Process invented in 1842 by Sir John Herschel.
MP procédé — reformulated non-toxic chemistry, signed by Tristan Sidem.
View the procédéHistory of the process
Cyanotype is one of the oldest photographic processes still practised today. It was invented in 1842 by Sir John Herschel, a British astronomer and chemist, while searching for a way to reproduce his scientific notes. The process relies on the photosensitivity of iron salts which, when exposed to ultraviolet light, produce an intense pigment — Prussian blue.
It was Anna Atkins, a botanist and friend of Herschel, who elevated the cyanotype to an art form. Between 1843 and 1853, she produced "Photographs of British Algae: Cyanotype Impressions", widely considered the first book illustrated with photographs. Her botanical plates — seaweed placed directly on sensitised paper — are now held in the world's greatest institutions: the New York Public Library, the Victoria & Albert Museum, and the Getty Museum.
Our approach
Every cyanotype print made by Maison Picturale is a unique piece, produced entirely by hand in our Parisian workshop.
The paper used is a 100% cotton satin watercolour stock at 640 g/m², chosen for its ability to absorb the emulsion deep into its fibres — the Prussian blue does not sit on the surface but dyes the very fibre of the paper. This ensures exceptional longevity and a tactile quality reminiscent of engraving.

Indicative pricing — the exact rate depends on the chosen procédé, support and finish.
Contemporary print after a work in the public domain (CPI L.123-1, 70 years post-mortem). Hand-crafted reinterpretation by Maison Picturale's master printers — this is not an original vintage by the master. The mention 'after [Master]' is systematic on the print and on the certificate of authenticity.
