Maison Picturale reinterpretation in gum bichromate
About this work
Mediterranean street view of Menton (anglicised 'Mentone') on the French Riviera, published in Camera Notes vol. 3 n° 3 — Alfred Stieglitz's pre-Camera Work journal of the Photo-Secession. The work testifies to Demachy's travel practice in the south of France, an extension of the bourgeois itinerary of a Parisian banker who turned his vacations into pictorialist material. Geographically, Menton sat at the edge of Italy and was, around 1900, one of the Riviera resorts most associated with British wintering and Belle Époque tourism — a context Demachy treats not as travel reportage but as a tonal exercise: light architecture, calligraphic shadows, the picturesque dissolved into pigment. By 1900 Demachy, co-founder with Maurice Bucquet of the Photo-Club de Paris (first Salon de Paris 1894) and member of the British Linked Ring since 1895, had positioned French pictorialism as a peer of British and American photo-secessionism. The Camera Notes appearance is itself significant: it places Demachy directly in the orbit of Stieglitz seven years before their 1907 public quarrel, when the American would turn against the gum process as overworked and pictorially mannered. 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 — the Mediterranean street is sculpted as pigmentary planes rather than recorded as architectural detail. At Maison Picturale, this kind of Mediterranean townscape is re-transposed in non-toxic gum bichromate following the chemistry reformulated by Vision Picturale, on 640 g/m² cotton paper, preserving the master's pictorial vocabulary while removing 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.
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.
