Maison Picturale reinterpretation in platinum-palladium
About this work
Among the earliest photographs of Chenonceau, made during the Mission Héliographique of 1851 — the first state-commissioned photographic survey in history. Jean-Baptiste Gustave Le Gray (1820-1884), trained under the painter Paul Delaroche and inventor that very year of the dry waxed-paper negative — a faster, sharper, more travelable alternative to Talbot's calotype — was one of five photographers (with Hippolyte Bayard, Édouard Baldus, Henri Le Secq and Auguste Mestral) sent by the Commission des Monuments Historiques to document medieval and Renaissance heritage threatened by neglect or restoration. Chenonceau, with its sixteenth-century arches astride the Cher, sat at the centre of Le Gray's Loire campaign. The waxed-paper negative, exposed in long, patient sessions, produced the gentle tonal envelope and translucent shadows visible in this plate (held at the Bibliothèque nationale de France and at the Médiathèque du Patrimoine, the official Mission archive). Le Gray would go on to become photographer to Napoleon III, to run a teaching school for amateurs — Maxime Du Camp, Léon de Laborde, the Marquis de Bréval — and to make the celebrated combined-negative marines of 1856-1858 (The Great Wave at Sète, The Brig), before financial collapse forced him into Egyptian exile in 1860; he died at Cairo in 1884. Maison Picturale process transposition: the original salted paper print from a waxed-paper negative belongs to the historical paper-paper chain. The contemporary non-toxic equivalent in the MP catalogue is the Vandyke print on 640 g/m² cotton paper — a reformulated salted-paper-family iron-silver process that reproduces the warm matte tonality of the Mission Héliographique tradition.

Procédé Transposition
Print like Gustave Le Gray 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.
Noble metals — platinum and palladium — on 640 gsm cotton paper. The longest tonal range in all analog photography.
MP procédé — reformulated non-toxic chemistry, signed by Tristan Sidem and Raphaël Lebas de Lacour.
View the procédéHistory of the process
The platinotype was invented in 1873 by the British engineer William Willis, who patented the process that same year under the name Platinotype Process. In 1879 Willis founded the Platinotype Company, which sold platinum-sensitised papers across Europe for several decades. Palladium was introduced in the early twentieth century as an economical variant, giving nothing away on tonal quality.
Platinum-palladium quickly became the process of choice for the masters of fine-art photography. Alfred Stieglitz, Edward Weston, Alvin Langdon Coburn and Frederick H. Evans made it their signature process, and their original prints held at the Royal Photographic Society in London, at George Eastman House in Rochester and at the Metropolitan Museum of Art in New York still testify to platinum's tonal perfection. Stieglitz wrote that platinum offered a wider scale of greys than any other process.
Our approach
Every platinum-palladium print made at the studio at 1 passage Dagorno is a unique piece in a very limited edition, intended for serious collectors and institutions. The cost of platinum and palladium salts — noble metals whose prices follow the financial markets — makes this our premium process. Each print is prepared, sensitised and developed by hand by our master printers.
Our 640 gsm 100% cotton satin watercolour paper suits platinum-palladium particularly well: its pure cotton fibre, free of optical brighteners and alkaline additives, lets the metal salts embed deep in the paper, and its satin surface fully reveals the process's unique warm tonality and exceptional tonal scale.
Inside our studio

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.
