    That, or a luminance meter such as is used in film or TV stage
    lighting. They're usually used in an 'incidence' mode, measuring light
    falling on the object, not reflected from.

    They give an 'absolute' light reading. Then you have to calculate the
    various parts of the exposure equation.

    The term to look up is "Footcandles".
