Predictions from 1921
Henry D Hubbard
Secretary, US National Bureau of Standards
Dare we expect a camera with automatic focusing, automatic aperture adjustment, a camera recording in full color, with bi-visual stereoscopic effect, developing the picture instantly, telegraphing the pictures, exactly as recorded automatically to be filed, and with mechanism for instantly locating any film without index, and exhibiting it immediately, a camera with self-sensitizing plates on which no separate pictures but a continuously changing picture is formed and erased after being telegraphed to the storage room.
