I found on the github page that there is a patch that added code to the cameras.xml file to add support for the Z 9 and it worked for the person that posted and possibly for someone else (I can't really tell from their post) but it did not work for me. Is this a possible workaround or is this patch supposed to work?
Code:
<Camera make="NIKON CORPORATION" model="NIKON Z 9" mode="14bit-compressed">
<ID make="Nikon" model="Z 9">Nikon Z 9</ID>
<CFA width="2" height="2">
<Color x="0" y="0">RED</Color>
<Color x="1" y="0">GREEN</Color>
<Color x="0" y="1">GREEN</Color>
<Color x="1" y="1">BLUE</Color>
</CFA>
<Crop x="0" y="0" width="0" height="0"/>
<Sensor black="1008" white="15892"/>
<ColorMatrices>
<ColorMatrix planes="3">
<ColorMatrixRow plane="0">13389 -6049 -1441</ColorMatrixRow>
<ColorMatrixRow plane="1">-4544 12757 1969</ColorMatrixRow>
<ColorMatrixRow plane="2">229 498 7390</ColorMatrixRow>
</ColorMatrix>
</ColorMatrices>
</Camera>
Still, when I try to open my Z9 image to compare it to my D850 image, it won't open. I am using the FTZ II adapter but that shouldn't affect the file, right?
