Maison Picturale reinterpretation in carbon transfer
About this work
Panoramic view of the industrial complex of the Gouhenans salt works in Haute-Saône, where Louis-Alphonse Poitevin (1819-1882) served as engineering director from 1851 to 1855 — the very period during which he developed the colloid sensitisation experiments that led, in 1855, to his three foundational patents on gum bichromate, the carbon process and photolithography. Trained at the École Centrale des Arts et Manufactures in Paris (class of 1843), Poitevin pursued in parallel an industrial career (salt works of Dieuze, Montmorot, Gouhenans; glassworks of Ahun-les-Mines and Folembray) and a photographic research practice that earned him the Duc de Luynes Prize of the Société française de photographie in 1862 and made him Chevalier de la Légion d'honneur on 24 January 1863. This wide view, held today at the Bibliothèque nationale de France (Gallica), is one of two surviving photographic plates by Poitevin documenting Gouhenans (alongside the courtyard view) — a self-portrait of the chemist's industrial environment at the exact threshold of his three inventions, and a rare specimen of 1850s industrial topography seen through the eyes of its director-engineer. The plate also belongs to the larger corpus of test prints Poitevin produced to characterise his procédés, photographing the locations and monuments he had access to during his industrial assignments and travels. At Maison Picturale, a panoramic industrial view of this nature can be reinterpreted as a contemporary carbon transfer print in the Noir Musée range (deep pigmented gelatin blacks) or as an Aquaprint gum bichromate using the non-toxic Vision Picturale reformulation — a direct homage to the inventor of the very process.

Procédé Transposition
Print like Alphonse Poitevin today — without the toxics.
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.
Multi-tone carbon transfer — the most permanent material in all of photography. Contemporary reinvention of the 1855 Poitevin procédé.
MP procédé — reformulated non-toxic chemistry, signed by Tristan Sidem and Raphaël Lebas de Lacour.

History of the process
The carbon process was invented in 1864 by Joseph Wilson Swan, the British chemist and inventor also known for his work on the incandescent lamp. He presented it to the Royal Photographic Society in London that same year, patented as the Carbon Process. The principle: a pigmented gelatin hardened by UV exposure through a negative, then transferred onto a final paper.
Carbon very quickly became the reference process for serious photographic publishers. The Lumière brothers' heliographic works in Lyon, the Autotype Company in London and the Braun firm in Dornach made it their industrial process for reproducing artworks for museums. Late nineteenth-century carbon prints held at the Musée d'Orsay, at George Eastman House in Rochester and at the Metropolitan Museum of Art still show their maximum density intact today.
Our approach
A Maison Picturale carbon print is a unique piece made by hand by the master printers of the studio at 1 passage Dagorno, Tristan Sidem and Raphaël Lebas de Lacour. Each carbon print takes several days of work: preparing the pigmented gelatin, UV exposure, transfer onto the final paper, controlled drying. It is a strictly museum-grade process, intended for serious collectors and institutions.
Our 640 gsm 100% cotton satin watercolour paper suits carbon particularly well: its weight supports the transfer of pigmented gelatin without distortion, and its satin surface fully reveals the slight low relief that signs the process in raking light. This conservation paper, free of optical brighteners, guarantees the work's permanence across centuries.

The Carbon transfer process is not yet offered at the studio: this print is made in Sanguine Aquaprint, the non-toxic watercolour gum.
Firm prices: they follow from the procédé and the paper format, as on our Process pages. 100% cotton paper, 640 gsm, deckled edges. Which formats are offered depends on the resolution of the reference file we hold for this work.
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.
