Ted why are you going through Rawdigger?

I find that RawDigger's RGB export preserves channel detail far better than SPP.

Observe how SPP crushes the green channel in the selected area. The foliage comes out quite similar. That means that using a 3-channel color mixer is far less effective on an SPP image than it is on a RawDigger RGB export.

SPP is rendering a daylight/natural light image: the channel gain and white balance matrix are not meant for infrared. And that remains true even if you capture a Custom WB off an 18% grey card, you'd need to capture it off an infrared reflective target − which I believe that the SD14 could... ?

Have you tried injecting your RT 3x3 colour matrix into an X3F for SPP to handle? I'd expect the results to be far superior. Then again, am I just wading into an ad for RawTherapee?

BBC disclaimer: other image editors and compositors with similar and/or extended toolsets are also available.
