P: Color temperature below 2000K

If you're using an Adobe DNG Profile installer downloaded prior to January 2018 it may be causing your issue.  At the below link the installer has been updated. Yes, it still says September 2012, but it has been updated with the new installer. Give it a try!

DNG Profile Editor (September 2012)

The DNG Profile Editor is a free software utility for creating or editing camera profiles.

Doesn't work anymore with the newer CC versions. What to do now? The DNG profile editor always throws the error "cannot complete operation" and even with a workaround (converting DNG to lowest version) eventually saves broken profile files.

The solution is to use a custom DNG profile for white balance as outlined in the article DP HOME has posted in this thread.

they do - RFTM how to handle WB for IR @ http://wwwimages.adobe.com/content/dam/Adobe/en/products/photoshop/pdfs/cs6/DNGProfile_EditorDocumen...

That is aggravating for sure.

I use the following work around.

White balance for IR photography.

While somewhat "niche", it is annoying that Adobe products don't support a more expanded white balance that would include IR images.  Even with a custom white balance set in camera, Adobe products don't support the more extreme white balances required for IR photography.  Having to import RAW files into Nikon Capture NX-D and then convert them to TIFF before importing into LR is not optimal from either storage or workflow perspectives.  Please consider a fix to this.

Yes, a lot of the light sources that we photograph at night have extremely low color temperatures. Sodium vapor lights for example. If we could choose lower color temps we would be able to balance these lights in a way that we cannot do now.

I think would be potentially useful to have a color temperature below 2000 and a tint below -150 for InfraRed Photography.

As for example.. in this step-by-step it suggests you minimize out the color temperature.

But this still makes you dependent on going B&W, though if it went lower on the scale and you were doing it for effect would it not be useful vs. being constrained to just B&W too or even if B&W useful?

Actually, it can be done quite easily - see my first reply post up top.

Also, I've just made it "child's play" to edit color profiles for this purpose.

Yes, candlelight cannot be done right in LR...
