History
Francis Galton’s composite portraits and the politics of classification
Galton used layered portraits to visualize supposed human “types”; the practice exposes the danger of treating images as scientific proof.
Francis Galton’s composite portraits were made by superimposing exposures of different people. His aim was to make an average image for a category, but his categories reflected eugenic assumptions rather than neutral biological facts. The work is an important history of photography and a warning about visual authority.
A technique used to classify people
The Met dates Galton’s Composite Portraits of Criminal Types to 1877 and describes his method as a way to visualize different human types. He began with portraits of convicts, hoping to associate facial features with criminality, then made composites of other groups.
Galton’s theory was tied to eugenics, a discredited project of managing human heredity. A composite image may look objective because it is mechanically made, but the decision about whose faces to combine—and what category they represent—is ideological.

What the process can and cannot show
Overlaying faces can produce an image that smooths individual differences into a visual average. It can illustrate a printing technique, but it cannot establish that a social identity has a single measurable appearance.
The Met’s record includes the group labels Galton chose, allowing viewers to analyze the historical framing instead of mistaking it for contemporary science. The archive is valuable partly because it makes the assumptions visible.

A caution for portrait culture
Identity photography often promises reliable recognition. Galton’s composites show how easily the idea of an objective face can be used to support unjust classification when the method begins with a biased question.
The contrast with a self-directed booth portrait highlights who creates a category, who is photographed and how an image is used.
