    Hi Andrey,

    I'm slowly dipping into the film world so I definitely find this interesting. Am I right in thinking that you are trying to match images taken on a stills camera in RAW (which camera?), to footage taken on a film camera (which one?)

    Film camera's tend to have much more dynamic range and RAW footage is very flat, so even if you apply a LUT that is provided, your still image would look completely different, as RAW files on still camera's are relatively crunched already.

    IMHO best way would be to try to match it using capture one (levels, curves, colour wheels). I tend to lift shadows by +20 on levels to give a more cinematic look (among other things), but each case is different.

    Ok, to be more specific I am trying to match video shot on Red Epic dragon and then graded in Media Composer to a specific film look, to a shots on Nikon camera. Artist that is creating graded footage, is willing to give LUTs, but again playing with C1 setting on every shot is very long process. Right now I just you Photoshop and Apply 3D LUT that he provided to me and boom. Fast and easy. Also there are a lot of film simulation and effects simulation LUTs so it is a great feature to have in C1, to further integrate with other workflows.

    The thing I don't understand is how a LUT can make a Nikon RAW file look anywhere near similar to Epic RAW? The two RAW files, in their neutral state, should be completely different (epic being super flat?). So in my head if you were to apply a LUT that was made for Epic onto a Nikon file, wouldn't it be over contrasty?

    Correct me if I'm wrong!

    Yes, if they are set up different. But in our case both Nikon and set flat. But what I need more from LUT is color grading which is made by film editor, which effects whole film frame, i.e adding specific film look. Just not manually redo this look in C1 but instead import LUT generated by composing application is much simpler.

    Have you spent any time investigating the possibility of converting a LUT to an ICC profile? I haven't tested any of the options out there, but given that ICC is the standard in still photography (and also what Capture One runs with) I'm betting this will be your best option.

    A quick spin on google brought a these guys up (but there's plenty more):

    Thank you.
    I've haven`t though of idea converting to ICC. But can I actually apply ICC profile?

    Yes. Capture One works quite well with ICC profiles, as do many other image editing programs.

    In fact, a common approach is to create a number of adjustments in Capture one and then save those as an ICC preset (for things like camera calibration profiles) to re-use in the future.

    This sounds to me like it'll be your best bet.

    Yeh, make perfect sense. Thank you again.
