    The Histogram probably shows the consequences of some "auto" black and white point adjustments made by C1.

    Exposure Evaluation presents the image as exposed, with only white balance and base characteristics applied.
    Histogram presents the image as currently adjusted and ready for export.

    They might be nearly identical (if you haven't changed any default adjustments) or radically different (e.g. if you've applied strong adjustments like curves, exposure, recovery etc).

    Another minor difference is that Exposure Evaluation information is available via applescript which we demonstrate in our automated filter-by-over-or-under-exposure tool in our applescript kit for C1.

    You might enjoy visiting NYC and attending one of our C1 Masters classes; it covers workflows that leverage both histogram and exposure evaluation, along with many many other topics you didn't even know that you didn't know .

    Exposure Evaluation mean Belichtungsbeurteilung?

    Histogram from back or in COP?

    I have not changed any default adjustments.
