Maison Picturale reinterpretation in gum bichromate
About this work
Early allegorical portrait of a young woman as 'Primavera' (Spring) — one of Demachy's foundational pictorialist works, dated either 1896 (Wikimedia filename) or 1899 from a citation in Robert de La Sizeranne's La Photographie est-elle un art ?; we use the broader c. 1896-1899 range pending a catalogue raisonné resolution. The work belongs to the first French pictorialist generation, the years immediately following the founding of the Photo-Club de Paris by Demachy and Maurice Bucquet, whose first Salon de Paris opened in 1894 as the European counterweight to the British Linked Ring (into which Demachy was elected in 1895). Iconographically Primavera echoes the Quattrocento allegory of Botticelli — a learned reference natural for a banker's son who frequented the Alphonse Daudet literary circle and considered photography a department of pictorial art rather than a recording instrument. The La Sizeranne mention is itself a marker: La Photographie est-elle un art ?, published in 1899, was the foundational French apology for pictorialism, and Demachy's image circulated as visual evidence for the thesis. Technically the print is a gum bichromate: gum arabic sensitised with potassium bichromate, charged with watercolour pigment, exposed under the negative and brushed back manually — the halo of light around the figure is sculpted into the matter rather than captured by the optic. The work belongs to private collections; reproductions circulate through period publications including La Sizeranne. At Maison Picturale, this allegorical typology is re-transposed in non-toxic gum bichromate following the chemistry reformulated by Vision Picturale, on 640 g/m² cotton paper — the painterly aura of the master preserved without the bichromate sensitiser.

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.
