The Kodak n°1 box camera, the first easy-to-use camera, is introduced with the slogan, "You press the button, we do the rest." Louis Le Prince makes Roundhay Garden Scene. It is believed to be the first-ever motion picture on film.
The lens was focused either by sliding or with a rack and pinion mechanism.

The plate was then carried to the camera in a light-tight plate holder. Withdrawing a protective dark slide or opening a pair of doors in the holder exposed the sensitized surface within the dark camera and removing a cap from the camera lens began the exposure, creating an invisible latent image on the plate. Depending on the sensitization ...
[35] [37] [38] [39] The Duplex's name was a reference to the SLR's one lens performing both viewing and imaging duties, in contrast to the two separate viewing and imaging lenses of the twin lens cameras (first production 1882 [Marion Academy; UK]; not necessarily twin-lens reflex [TLR] camera, invented 1880 [one-of-a-kind Whipple-Beck camera ...
