History
What was Niépce’s heliograph?
Niépce used a light-sensitive plate and long exposure to make an early surviving photograph from a camera view.
The V&A describes Joseph Nicéphore Niépce’s heliograph experiments with bitumen-coated plates and identifies View from the Window at Le Gras, made around 1826 or 1827, as the earliest known surviving photograph made in a camera.
The subject is a view from a window, not a portrait
The subject is a view from a window, not a portrait. The process required light to change a coated surface and a chemical treatment to preserve the result, linking optical projection to a lasting image.

It made the sitter, not a landscape
The photobooth later reversed the emphasis: it made the sitter, not a landscape, the standard subject and built a fast service around the exposure. Niépce’s work is an important photographic precursor, but it was not an automatic portrait machine.

Sources distinguish an early surviving camera image from a print
Treat “earliest” claims carefully: sources distinguish an early surviving camera image from a print reproduction made from an engraving. The distinction is useful because both may be heliographs but record different things. Niépce’s importance lies in linking a camera projection to a surface that could retain an image after exposure.
