    I have read on the ICC website that color management has not taken hold
    in digital yet

    but to characterize a digital camera you need white point (illuminant) data

    right now the choices are to make an assumption of white point from
    scene data, or use the RAW image, both might be "good enough"
    approaches, both might need editing

    but if you had a inexpensive spectroradiometer onsite, you could
    combine that spectral data with the contrast of the sensor and the
    spectral distribution of the sensor filtration and make a profile
    mechanistically

    if your color management system allowed for that approach, and the
    spectroradiometer fit the price point of your market

    probably doesn't have to be perfect spectroradiometry in some
    applications since illuminance standards have some assumptions

    and you don't need the data if you know the spectral data of your
    lighting in this approach

    same kind of thing if you want to unbuild a negative back to the scene
    rather than intend it to printing densities for an optical print, lots
    of medium data needed for the first approach, and that data would
    probably reduce editing in print intentions too
