Colour Tint when Using B&W

Miles2
When I click on 'Enable Black & White" on one of the three machines on which I have C1, I get something like a sepia tone which I don't seem to be able to correct in C1 and have to desaturate in Photoshop. Is there something I am missing in one of the settings ? I don't have any presets or styles applied. The other 2 machines are fine.

It's probably something really simple but it's been bugging me for ages.

Any suggestions welcome. Thanks.

    I suggest you take a look at the second tab in the B&W tool, Split Tones and set all sliders to zero.

    Paul,

    That was about the first thing I did but it doesn't eliminate this colour cast.

    MIles,
    Is it possible to supply files in your thread?
    Is it possible that what your seeing is a result of a Monitor Calibration?

    The Black and White tool, unless set otherwise, neutralizes RGB so there is no color.

    Drew,

    I don't think it is monitor calibration that is at fault. I have dual NEC Spectraview 27" monitors which are quite carefully calibrated. Secondly, when I export the TIFF file from C1 and then de-saturate it in Photoshop it's clearly B&W on screen and in print.

    I won't have access to this particular machine for a couple of weeks but on my other main system to which I have transferred my last session C1 session the images are correctly shown as de-saturated.

    I am not sure what you'd like me to post in terms of files. I can post the TIF file processed on the problem machine and the TIF file of the same image correctly processed on my other main machine, A hint as to how to attach files would be appreciated.

    Whilst I believe that my B&W Tool settings are right is there anywhere else where a setting could cause this to happen.

    Many thanks
    Miles.

    Miles,
    You can reset your workspace to defaults, or reset the tool itself. I would suggest you pack the File as an EIP and then send it to us through a support case but as the issue only seems related to that single computer, I think the issue is related to a peripheral setting and not Capture One.

    Drew,

    I've now got access again to the affected machine.

    I've replaced all the workspaces from the PC which is working correctly. I'm still getting the sepia-ish tone when I enable B&W in the B&W tool. All colours are set to zero and all split tones are set to zero on the Split Tones tab.

    However when I take saturation to -100 in the exposure tab I am getting a correct B&W image. That seems to confirm that it is not a monitor calibration issue and that it is a C1 issue (or so it seems to me).

    If I do a complete re-install from scratch what do I need to make sure I remove from my system so as to make a completely fresh start (Mac OS) ?

    MIles,
    Please create a support case and we'll have a closer look.
