    Hi:

    What entities -- excluding wavelength of light -- 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 downshift the frequencies of those
    entities to 0.1 Hz?

    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 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?

    What other than spatial frequency would be measured in Hz in my above
    scenario?


    Thanks

  2. I would like to know what you smoked when you made up this question as
    it seems quite potent hallucinating stuff. Can I buy it online?

    Thanks!
