Lightroom/Camera Raw: I can no longer create a profile for an IR camera with the new profile SDK.

I have a camera converted to super color IR by Life Pixel. The method Life Pixel recommends to create a white balance profile is to export a raw file created with the IR camera as DNG. Next, run the DNG Profile Editor, open the file, click the Color Matrices tab, move the temperature slider all the way to the left, then export the profile for use in LR and ACR. This is necessary because the DNG Profile Editor lets you select a much lower color temperature than the Temperature sliders in LR/ACR.

The DNG Profile Editor has been abandoned by Adobe. It runs on Windows but does not scale on high resolution monitors. I read online that it does not run at all on Mac High Sierra or later.

The new Adobe Profile SDK, which is Adobe's replacement for the DNG Profile Editor, let's us create profiles in ACR. Unfortunately that does not work for those of us with IR cameras because the Temperature slider in ACR does not have the range of the Temperature slider in DNG Profile Editor as stated above.

Yes, the new profiles are XML and can be edited with a text editor but the temperature in DNG Profile Editor has a range of +-100 while the temperature sliders in ACR/LR are in degrees Kelvin. The problem is that the number stored in the new XML profile file appears to have a range of +-100 which as no relation to the color temperature in Kelvin or to the +-100 scale in DNG Profile Editor. So, I can edit the profile but I have no way to know what value to assign to the temperature.

So, what's an IR camera owner to do? If anyone has a solution that works with the new profile format I would love to try it. Thanks.

A couple of items for you:

The DNG Profile Tool is still the preferred tool for this type of work.  The SDK isn't really meant to be a replacement for the DNG Profile Creator.  That said, the tool is under continued development.

It currently works on all versions of Windows 10, though the experience is suboptimal from a display resolution perspective.
It should work on Mac through version 10.14.  I've verified it works through 10.14.6 on my machine. 

I've spoken with the Camera Raw engineering team and they will be working on this in the future.
