It is a camera with no lenses, it was documented in book in the 18th century. The first creator was Joseph Niepce and he did that from the stair's window.

Explanation:

A pinhole camera is a camera with no lenses, a simple camera and it has an aperture that is very small. Those cameras are easy to make and those cameras are considering a light-proof box and in that box, we can find a small hole, circle on the one side. Some of them are having ground glass or a plastic screen and it can allow users to set up the point of view that they want before taking the picture and inserting the film. We know that these cameras existed because of the ''pin-hole'' term and it is found in 1764s James Ferguson's book ''Lectures on select subjects in mechanics, hydrostatics, pneumatics, and optics''. The books are showing and documenting that those cameras were existing before the 19th century.Joseph Nicéphore Niépce created the first photograph, it was taken from his window in France and the first photo was taken in 1826. He was doing it by a camera obscura and he was focusing it ono the plate and the whole process was lasting 8 hours long. He did also developed heliography.
