Maison Picturale reinterpretation in gum bichromate

About this work

Portrait of Magdeleine Guipet, a Parisian figure photographed by Demachy in the early 1900s. The print is held at the Bibliothèque nationale de France and circulates digitally through Gallica, France's photographic memory institution where Demachy deposited a substantial portion of his print archive. The image belongs to the bourgeois portrait practice that occupied Demachy alongside his more public allegorical works: a banker's son and member of the Alphonse Daudet literary circle, he photographed the Parisian society of the Belle Époque the way a portraitist of the third Republic would have painted it — pigmentary atmosphere over likeness, identity dissolved into pictorialist matter. By c. 1905 Demachy was at the height of his European influence, co-founder with Maurice Bucquet of the Photo-Club de Paris (first Salon de Paris 1894), member of the British Linked Ring (1895), and finalising with Constant Puyo the writing of Procédés d'art en photographie (1906), the manual codifying gum, oil and bromoil. The choice of an identified Parisian sitter — Magdeleine Guipet — places the work in the tradition of the named bourgeois portrait inherited from Carolus-Duran and Sargent, a portraiture of social acknowledgement that Demachy translated into photographic pigment. Technically the print is a gum bichromate: gum arabic sensitised with potassium bichromate, charged with watercolour pigment, exposed under the negative and brushed selectively under tepid water — Magdeleine's features emerge from the pigment as if the photograph were a charcoal drawing. At Maison Picturale, this kind of Belle Époque portrait is re-transposed in non-toxic gum bichromate following the chemistry reformulated by Vision Picturale, on 640 g/m² cotton paper — the painterly likeness of the master preserved without the bichromate hazard.

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.

Multi-layer gum bichromate. Each pigment laid separately — VP reformulated recipe, no chromium VI.

MP procédé — reformulated non-toxic chemistry, signed by Tristan Sidem.

History of the process

Watercolour gum (gumprint, gum bichromate print) is one of the most versatile and oldest photographic processes. Its principle was discovered by Mungo Ponton in 1839, who observed that paper soaked in potassium bichromate hardened under light. It was Alphonse Poitevin who, in 1855, had the idea of mixing watercolour pigment with sensitised gum arabic: by exposing this layer under a negative, the exposed areas harden and retain the pigment while unexposed areas dissolve during washing.

The gumprint enjoyed its golden age between 1890 and 1920, within the Pictorialist movement. Photographers such as Robert Demachy, Edward Steichen, and Gertrude Käsebier used it to create images halfway between photography and painting, asserting photography as a fine art in its own right. Each colour layer is applied, sensitised, and exposed individually — a four-colour print therefore requires a minimum of four passes.

Our approach

The gumprint made by Maison Picturale is an entirely handmade print where each colour layer is a unique pictorial gesture.

We work on 100% cotton satin watercolour paper at 640 g/m², capable of withstanding multiple watercolour passes without warping. In four-colour mode, each print requires four successive layers — cyan, magenta, yellow, and black — each individually sensitised, exposed, and developed. The result is an image with vibrant colours and a grain impossible to achieve with digital printing.

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.
