The 1840s–1890s transformation of scientific representation — when the arrival of the camera reorganized the epistemological landscape within a generation, and the paradigmatic historical analog for the AI transition.
The photograph arrived in European scientific practice in the 1840s with an argument that addressed the specific anxiety accumulating within the sciences: the distorting influence of human subjectivity on the production of knowledge. Where the illustrator interpreted, the camera recorded. Where the illustrator selected, the camera captured. The photograph appeared to eliminate the problematic element — human judgment — by producing images through a causal chain that ran from object through lens to plate without passing through a consciousness. Within a generation, mechanical objectivity had displaced truth-to-nature as the dominant epistemic regime, and scientific communities across disciplines had restructured their practices around the new technology's confidence artifacts.

The transition is worth studying in detail because its structural features recur, with variations, in every subsequent knowledge-technology transition — including the AI transition now underway. The pattern has five elements that Daston's research documents with precision. A threshold crossing occurred when the technology's
