    Does anyone here know how to convert a lux number to an f stop and
    shutter speed for a given film speed? Is there a handy chart on the net
    that I can't find? I have this security camera that has a .1 lux rating
    and I would just like to know what exposure that relates to.

    My understanding of Lux as a measurement was/is 1 lux = 1 candle at 1 foot.

    I.E. in a darkened room a lit standard household candle lit will emit 1
    "lux" at 1 foot distance from the candle.

    so therefore in the case of security camera it is capable of seeing a tiny
    amount of light at night, or needs very little light to illumate the subject
    for it to see it.

    Of course the above might be wrong.

    That's pretty close. According to my book of conversions, 1 lux is 1
    lumen/sq. meter, or .0929 footcandle. Whatever, it close enough, and I
    doubt that any of will use it very much. :)
