Were there cameras in 1915?
Of course, all of the present types except digital, not yet
invented. this included: Polaroid, Instamatic (l963-85), 35MM
single lens reflex, 35mm rangefinder, Press and View bellow cameras
(such as Speed Graphic and Linhof) miniature or subminiature
cameras such as the Minox, and of course the now somewhat moribund
narrow-gauge(8mm, super-8 and l6mm) home movie cameras! There were
also stereo or 3D cameras of different types, this type now
(metzs-a metz) out of style.
