Reference Input Medium Metric, RIMM, ERIMM

    from what I read ProPhoto RGB is the defacto RIMM now

    but this is a case I side with a film metric, negatives have long
    dynamic ranges to accommodate exposure latitude

    chromes depend on good exposure meters and lighting meters to get the scene

    I don't think digital cameras have the exposure latitude of negatives yet

    ROMM is better than RIMM for relative colorimetry (appearance) in most
    professional use cases because it has the practicality of proofing
    approvals,, soft or hard, being built into the workflow

    maybe use cases will evolve around RIMM and ERIMM

    film has a narrower dynamic range.
    in other words, narrower.
    they have for years.

    guess I was wrong, a digital camera RIMM/ERIMM would be a better choice
    overall, if the customer wasn't provided a choice for his use case

    well cell phone sensors don't
    everytime I get a picture taken my dark hair is clipped

    cellphone sensors are tiny so they have less dynamic range, not because
    they're digital, but because they're tiny.

    which do you think would give a better print, a 35mm film camera or a
    minox subminature camera? same thing with digital.

    compare like with like, which would be 35mm film with a full frame

    however, even a crop sensor will beat film and many compacts.

    with film the size of the camera only affects the image structure
    (grain, sharpness), not the color which contains dynamic range

    this applies to digital too, I suspect a CIE filtration will eventually
    prevail over the Bayer type filtrations, it is an evolution toward color
    and not hybrid film modeling and the limitations thereof, film is
    modeled in hybrid analog and hybrid digital systems, even if that
    entails just measurement of density or spectral considerations, there
    has to be a recognition of such equipment even in strictly sensitized
    materials like photographic film and paper

    I had a good boss at Kodak R&D who told me the system of film/paper, etc
    doesn't work, I interpret this as meaning that there will be a
    prevalence of "good enough" color some places as opposed to rigamoral,
    and the prevalence of editing and "more attractive color",, both have to
    start with the intent of accurate appearance or color, just to make
    sense of what you are doing if you want a central system approach with
    some defined open systems and standards

    obviously he means blocked shadows.

    the same thing in application, just different words

    even considering push and pull chemical processing for under and over
    exposures respectfully?
