Autochrome Lumière

The Autochrome Lumière process was invented by the Lumière brothers, Louis and Auguste, in 1903.

The key innovation of the Autochrome Lumière process was the use of a mosaic screen, which consisted of a grid of tiny starch grains dyed with red, green, and blue dyes.

Light passed through the mosaic screen and was recorded on a panchromatic emulsion, which was sensitive to all colors of light.

The Autochrome Lumière process had several advantages over previous color photography processes. It produced color images that were more accurate, it was relatively easy to use, and it was inexpensive.

The Autochrome Lumière process had several disadvantages. It was time-consuming to produce Autochrome Lumière images, they were not very durable, and they were not very sharp.

The Autochrome Lumière process was first commercially available in 1907.

The Autochrome Lumière process was discontinued in 1935.

Edward Steichen was an early adopter of the Autochrome Lumière process and used it to create some of the most iconic color photographs of the early 20th century.

The first color photograph taken with the Autochrome Lumière process was called 'The Rose' and was taken by Louis Lumière in 1903.

The Autochrome Lumière process could reproduce three colors: red, green, and blue.

The resolution of an Autochrome Lumière image was approximately 1.5 megapixels.

The typical exposure time for an Autochrome Lumière photograph was approximately 1/10th of a second.

The typical size of an Autochrome Lumière transparency was 4x5 inches.

The typical cost of an Autochrome Lumière transparency was approximately $10.

Approximately 10 million Autochrome Lumière transparencies were produced in total.
