Maison Picturale reinterpretation in gum bichromate
About this work
Figure study published as plate 6 of Camera Work n° 16 (October 1906), reproduced as photogravure from an original gum bichromate print. The composition tightens on the model, treated in broad pigmentary planes — emblematic of Demachy's mature phase where photography deliberately approaches charcoal drawing. The Camera Work n° 16 issue was a dedicated Demachy portfolio, the most extensive American platform the French pictorialist would obtain; one year later, in 1907, his public quarrel with Alfred Stieglitz would end the trans-Atlantic alliance, Stieglitz turning against the gum process he had earlier championed in favour of Paul Strand's straight photography. By 1906 Demachy was at the summit 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 since 1895, banker's son with no profession to exercise, lettered amateur close to the Alphonse Daudet literary circle, and co-author with Constant Puyo of Procédés d'art en photographie (1906) — the manual codifying gum, oil and bromoil for the French pictorialist generation. The plate's title — simply 'Study' — is itself a programmatic refusal of narrative: the photograph is presented as a painter's exercise. Technically the print is a multi-coat gum bichromate: gum arabic sensitised with potassium bichromate, charged with watercolour pigment, exposed under the negative and brushed selectively under tepid water — body and ground sculpted as pigmentary matter rather than recorded as silver-tone detail. At Maison Picturale, this kind of study is re-transposed in non-toxic gum bichromate following the chemistry reformulated by Vision Picturale, on 640 g/m² cotton paper — the sculpted matter preserved without the historic potassium bichromate.

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.
View the procédéHistory 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.

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.
