Early 1900s color photos look like literal dreams

Born into a wealthy family, John Cimon Warburg's chronic asthma made it difficult for him to work a full-time job. Instead, he chose to devote his time and money entirely to the study and practice of photography.

He was particularly interested in working with Autochrome, one of the earliest color photography processes.

Patented by the Lumière brothers in 1903, Autochrome produced a color transparency using a layer of potato starch grains dyed red, green and blue, along with a complex development process.

Autochromes required longer exposure times than traditional black-and-white photos, resulting in images with a hazy, blurred atmosphere filled with pointillist dots of color.
