    What entities in a single stationary image of the negative of a B&W
    film are measured in Hz?

    What will the image look like if I change the frequencies of those
    entities to 0.1 Hz?

  2. It's our resident moron again. Your IQ is equaly to the frequency of
    0.1 Hz........

    The wavelength/bandwidth of any transmitted light can be measured in Hz.
    It won't be visible.
    (A bit like your intelligence)

    None. Hertz is the reciprocal of the period with respect to time. A
    B&W image does not change.

    Hz is commonly used to measure cycles-per-constant-time [usually in
    seconds] but could also be used to measure cycles-per-constant-
    distance [as in the cycles-per-meter in spatial frequency]. Right?

    If an single stationary image is low-pass-filtered it will look
    duller. If it is high-pass-filtered it will look sharper. This is an
    example of frequency-processing in which the Hz is *not* "the
    reciprocal of the period with respect to time".

    In this case Hz measures the reciprocal of the period with respect to
    distance. Right?

    No offense but forget about the wavelength or color of the light. The
    light is white. Irrelevant.

    Why not? If the image is big enough, won't it be able to contain a 0.1
    Hz spatial video signal?

    The light *may* be white, and it's the only thing NOT irrelevant to your
    stupid question since it does have a frequency bandwidth.

    Radiation frequencies of 0.1Hz are not visible to the eye.
    Which *IS* irrelevant to your original question, even IF it were possible.

    So how much did you earn from that reply? :)

    As said before frequencies of EM radiation are totally unrelated to
    this topic.

    LIGHT waves are the only "frequencies" relevant to a "negative of a B&W

    Nope. Spatial frequency is far more relevant.

  15. Yes, let us know how to earn that money, because I want to buy that
    same stuff GreenXenon is smoking. It seems to be a wicked drug :)

    You want to BUY it?
    I'd have thought you'd want to stay well away from anything that could
    destroy your brain that much!

    Mr.T, May 9, 2009
  17. Hey, I know you!

    Didn't know you were into photography as well!
