Focal-plane Shutter - History and Technical Development

History and Technical Development

The earliest daguerreotype (invented 1839) photographic cameras did not have shutters, because the lack of sensitivity of the process and the small apertures of available lenses meant that exposure times were measured in many minutes. A photographer could easily control exposure time by removing and returning the camera lens' lens cap or plug.

However, as one increased sensitivity process replaced another and larger apertures lenses became available during the 1800s, exposure times shortened to seconds and then to fractions of seconds. Exposure timing control mechanisms became a necessary accessory and then a standard camera feature.

Famous quotes containing the words history and, history, technical and/or development:

    All history and art are against us, but we still expect happiness in love.
    Mason Cooley (b. 1927)

    In front of these sinister facts, the first lesson of history is the good of evil. Good is a good doctor, but Bad is sometimes a better.
    Ralph Waldo Emerson (1803–1882)

    When you see something that is technically sweet, you go ahead and do it and you argue about what to do about it only after you have had your technical success. That is the way it was with the atomic bomb.
    J. Robert Oppenheimer (1904–1967)

    The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.
    Jean Baker Miller (20th century)
