The head rest was a unique device that was used in the first photographers’ studios, when the exposure time to take portraits was very long. It was used to hold the head of the photographed person from behind, motionless, while the camera shutter was open and the person portrayed had to stay in front of the camera without moving. The exposure time of a daguerreotype plate to light was initially between fifteen and thirty minutes, but after a few years it was reduced to less than one minute.
