    Sinar eMotion75 owners please help

    Hi all

    Someone offered me a Sinar eMotion75 digital back. Upon inspection I noticed something strange with the color balance.

    The color balance is set to daylight in the menu on the digital back (there is no auto color balance). The pictures I have taken seem to show up with wrong color balance on the back's LCD screen. I copied the raw files (.IA files) from the CF card to my computer and tried to use Iridient Developer and RawTherapee open them.

    In Iridient Developer:


    In RawTherapee:



    All using default values. Notice the greenish color in RawTherapee. Tint value in Iridient Developer seems strangely high. Once I drag it to 0, it turns as green as in RawTherapee. And there are pictures came out with same green color shift in Iridient Developer too. like this




    Sinar CaptureFlow doesn't seem to support opening raw files (I'm looking at using the back in the field so tethering isn't an option anyway). Neither Lightroom nor Capture One supports the raw format, so Iridient Developer and RawTherapee are the only options.

    Raw files can be downloaded here:

    https://www.dropbox.com/s/lv22navabr...EF3AE2.IA?dl=0

    And I can't get the color balance right for this one
    https://www.dropbox.com/s/qc3723puv2...EF4A66.IA?dl=0



    Any thoughts? I'm not familiar with backs of this age. Is it normal? I'm worried that, though fixable to certain degree in post processing, the green channel on the back may have problems, and could result in clipping or lose of dynamic range in certain scenarios.




    Also does the back support LiveView via the LCD (not tethered)? Can't seem to make it work.

    I used to own one of these backs and it should work with CaptureFlow.

    No live view on back, only tethered.

    Can't comment on the green cast, but it should look fine in CaptureFlow once white balanced.

    PS Also, I'm sure I used to process these files in Lightroom, but maybe they are not supported anymore. But as they are DNGs, they should be.

    Thanks Ben. Yes, CaptureFlow saves in DNG format which can be imported in Lightroom. Though I'm hoping to remove CaptureFlow from the workflow.
