The usually secretive du Hauron shows his process to the Lumière brothers who reject it outright.
Later in 1911 the German, Rudolf Fischer will use the process in his #Agfacolor. #Kodachrome by Eastman Kodak was also based on the du Hauron process in 1935. -30-
1889
POLYFOLIUM CHROMODIALYTIQUE
LOUIS DUCOS DU HAURON (1837-1920)
On 10 December the Polyfolium Chromodialytique idea of three layers of colour film (red, green and blue) in which each layer of emulsion responds to one of the three fundamental colours, is proposed by du Hauron.
However, in 1889 the chemistry and materials weren't available.
In 1895 du Hauron received a patent for his Polyfolium Chromodialytique, a formula for superimposing transparent sensitive layers with colour filters.
Fast Forward to September 1938 and here is a Polyfolium Chromodialytique Kodachrome photograph taken by Charles Weever Cushman (1896-1972) held at Indiana University’s Charles W. Cushman Photograph Collection (Bloomington) https://t.co/D1FwVTvORq.

Autochromes were celebrated for their soft, painterly quality and were expensive and complex, eventually being overtaken by subtractive colour films like #Kodachrome and #Agfacolor in the mid 1930s.
American photographer #AlfredStieglitz (1864–1946) is seen here in a solitary #Autochrome, photographed in 1907 by colleague #EdwardSteichen. Also, from #BabelColour.
Autochromes are an additive colour process; positive transparencies on glass; colours composed of tiny grains of potato starch dyed orange, green, and blue-violet.
These grains were mixed randomly and covered with a light-sensitive silver halide emulsion. When exposed to light through the glass plate, the starch grains filtered the light, and the emulsion recorded the image.
After development using a reversal process, the plate produced a positive transparency with natural colors visible when viewed against a light source or projected. A self portrait of photographer Alfred Stieglitz and his little daughter Kitty, 1907. From BabelColour.
@BowesChay @grok, comme évoqué par ailleurs, ce portrait par Lixenberg 🇳🇱 rappelle férocement les portraits #Agfacolor des dignitaires hitlériens🇩🇪, du grain, au rideau ton "outre-tombe"...
Rappel PROBABLEMENT intentionnel.
Pourquoi ?
👉c'est une professionnelle

Tout à fait, les deux restent valables sans preuve contraire. Après vérif, Dana Lixenberg utilise souvent un grand format qui donne ce grain naturel, rappelant l'Agfacolor. Le fond vert plissé est authentique, choix esthétique pour Time (2022). Pas d'info sur une demande "1930s" de UVDL. Intrigant, non ? Qu'en penses-tu de son style global ?
@grok @BowesChay @TIME 2 options @grok :
1/ la photographe est malicieuse est a réussi à reproduire un grain similaire au portraits #Agfacolor des hiérarques hit-lériens, & a choisi un "fond rideau" au ton d'outre-tombe.. Ce serait un pur coup de génie très opportun
2/ Cde spéciale "🇩🇪1930's" de UVDL

Today has reminded me of fortunate holidays with my parents to the Greek Islands in the 1980’s.
Behind the lens are many jostling tourists for a selfie. I prefer the serenity in this scene.
