  1. #1

    Default X-ray camera

    i have saw this add on hardwarezone, if your camera has a night shot just add a ir filter then it will become a xray camera.

    The usual IR photography is based on near-IR energy, it's not quite the same as the night vision type IR devices, or the Sony see-through cameras. They work on a different spectrum.

    Why does owning a Sony cam and IR filter make it illegal?

    No guide to which Sony models work.

    BTW. Where can you buy 1000 nm rated IR filters for $20 or $30? Those are probably the lower rating ones. Those high pass filter are very expensive. A Hoya one can cost you about $300.

    Technically, Xray and IR are on opposite sides of the visible spectrum. So the Sony camera with the IR filter is not an X-ray camera.

    The Sony camera has a night shot mode that is sensitive to IR. Our body emits IR that penetrates some types of clothing. Using a IR filter to filter out the visible spectum the camera then has the capability to see through clothings.

    I think owning the equipment may not be illegal, since it was sold commercially, but using the equipment to take see-through photos without the subject's prior consent should be illegal.
    As complexity rises, precise statements lose meaning and meaningful statements lose precision.

    Thanks for the layman explanation on how this see-thru feature works.

    Your last paragraph should be addressed to ckiang though.
