"In the late 1920s and early 1930s, photographer
Clifton R. Adams was
commissioned by the
National Geographic to document life in England. Adams’
beautiful autochromes—a process of producing color images by using potato
starch—present images that capture the last of an England that was slowly
heading towards modernity.
Adams, who died in 1934, was instructed to record its farms, towns and cities,
and its residents at work and play. The color images were produced using the
Autochrome Lumière, which was the most advanced color photographic process of
the day. The plates were covered in microscopic potato starch grains colored
red, green, and blue-violet, with about four million per square inch.
The gaps between the grains filled with lampblack, and the coated layer allowed
the exposure to capture a color image. The light passed through the color
filters when an image was taken, with the plate then processed to produce
positive transparency."
