I'd sure love to try to re-enact the process of the Bélinographe (1913) but I have no idea what exactly an "electric eye" is in 2022: "the transmitter traverses the original image point by point. At each point a measurement of light intensity[clarification needed] is made with an electric eye. The measurement is conveyed to the receiver. There, a variable intensity light source reproduces the light measured by the electric eye, while carrying out same displacements exactly. By doing this, it exposes the photographic paper and makes it possible to obtain a copy of the original image." #othernetworks
