# Autochrome colour photography

> The first practical colour photography: a glass plate coated with a mosaic of potato-starch grains dyed orange-red, green and blue-violet, developed into one positive transparency and seen against the light, in a diascope or projected. Exposures about thirty times longer than black and white kept the camera on a tripod and the subject still, so autochromists chose colourful, unmoving things: flowers and gardens, family portraits, people posed in streets. The grain screen gives soft, stippled colour, dark and greyed overall, with glowing reds and blues.

- Period: 1907–1935
- Where it began: Lyon
- Kind: Early processes
- Also called: Autochrome Lumière, Autochromes, Lumière autochrome plates

## How the look is made

- Choose the subject for its colour: flowers, fruit, a striped dress, a red tablecloth or a flower cart, set against grey stone, sky or foliage that lets the colour glow.
- Shoot in bright daylight with the camera on a tripod and expose for a second or more; ask everyone to hold still, and accept that anyone who walks through becomes a transparent ghost.
- Let the colour screen show: a fine, even stipple over the whole frame, dark and greyed in skies and shadows, with full strength only in the reds, blues and greens of the subject.
- Make one positive and leave it as it came from the plate: no retouching, no hand-colouring, no combination printing; show the original by transmitted light, in a viewer or projected, one picture at a time.
- Place people calmly in their setting at eye level and middle distance: seated in a garden, at a table, beside a balustrade or a cart, looking into the lens or out of the frame.

## How it is lit

- Bright outdoor daylight, summer sun or a bright overcast sky, because even a sunlit landscape needed about a second.
- Sitters in open shade, on a porch or by a large window, holding still for several seconds against a plain wall or a garden.
- Low sun behind a figure in a garden or meadow, so hair and a pale dress glow against darker foliage.

### A light plan from its choices (schematic)

- Key: the open sky, all around and above, soft.

## Camera settings

40–55 mm · f/5–f/8 · 1–30 s · ISO 0.1–0.3 (on 9x12), documented. Coe: 1–2 s at f/8 for a summer landscape in midday sun, 10–30 s at f/5 for a portrait in a well-lit studio, on a tripod behind the orange-yellow filter; ISO 0.1–0.3 worked out from those times. 9 × 12 to 13 × 18 cm plates with normal lenses (inferred).

## Directing people

Sitters hold a pose for one to several seconds: seated upright in a garden chair or on a bench, standing beside a table or a flower cart, children with flowers or fruit held in their laps. Faces are calm and unsmiling and many look straight into the lens; in art autochromes figures sit in profile or turn away, gazing into a garden or landscape.

## Styling

Choose things for their colour: red apples, a bunch of flowers, a striped or red dress, set in a lap or against grey stone and green leaves. Otherwise people wear their own clothes, everyday or festive, in their own gardens, homes and streets, and nothing else is arranged.

## Before you shoot it

Autochromes show real people: children photographed by their parents (Kitty Stieglitz, Heinrich Kühn's children), street vendors and passers-by posed in front of shops, soldiers in the trenches of the First World War. Albert Kahn wanted in 1912 to record 'practices and modes of human activity' whose 'fatal disappearance' he thought only a matter of time, and his operators and National Geographic's photographers pictured people abroad and in the colonies for European and American viewers. Jules Gervais-Courtellemont's plate of women and men in Bou Saada, French Algeria (c. 1909–1911), names no one: its original caption reads only 'Biskra, Oulad Nail', and the museum's revised caption still calls them 'dancers and musicians of the Ouled Naïl tribe', a label that, in the words of the photography historian Michel Mégnin, had become 'no more than a virtual tribe whose name signifies only a local prostitute'. National Geographic's own editor wrote in 2018 that for decades the magazine 'pictured "natives" elsewhere as exotics'. Show such plates with their captions and context, name sitters where the records do, and never use the style to cast anyone as an exotic or vanishing type; never generate eroticised orientalist 'dancers', harem or bathing scenes of colonised women. Generate only invented, clothed sitters, and never recreate a named sitter or a known plate (Kitty Stieglitz, Heinrich Kühn's children, Mary Warner). A generated image in this style is not an autochrome: label it as AI-generated and never sell or show it as a vintage plate or as a record of a real place, person or event.
