Description:
Lambert performed his first photometic experiments April 1755. Augustus to November 1757 Lambert extensively read on optics (Euler, Kästner) and started writing the Photometria. He continued the writing November 1759 to March 1760, having seen a copy of Bouguer's work on the measure of light in Holland (Mai 1758).
The work proposes to develop a measure and measuring methods for the intensity of light.
