Peter, Your starting point looks something like mine.
Here is what an image of mine looks like using my D810 590nm camera profile in ACR. I adjusted the white balance in ACR.
Once I go into Photoshop, I run an action to swap channels, and then fine tune the levels and brightness/contrast.
Finally, if I want B&W, I add a layer.
Great examples, Jon. Thanks! I don't think I'm getting much IR effect.....

I now use a 720nm converted camera. I make mostly B&W images with it, but sometimes I want the weird contrast of white foliage and deep blue skies.
Getting this has been difficult, with many processing attempts along the way that went nowhere, or were far too complicated.
I found Rob Shea's website recently and tried his LR-only color swap LUT method, and I gotta say, I like the preliminary results.
You create LUTs in PS, then the profiles can be used in LR. If, like me, you've been switching between the two often, there's no need to jump between them anymore.
I didn't find my camera listed on his Infrared Profile Pack, so I sent him a RAW image. Later that day, I had a profile from Rob, and I could now set up the LR color swap.
It's explained here: https://blog.robsheaphotography.com/...troom-lut.html
and here: https://blog.robsheaphotography.com/...-profiles.html
Here's a throwaway image I took yesterday just to see what I could get on a cool day with clear blue skies.
Once I created and installed the profiles, I saw better separation of sky and foliage right away. With the Invert profiles, I saw much less blue cast on non-sky areas.
I ended up making 4 profiles: Invert and Channel Mixer LUTs at -50 and -100 saturation.
So with one click, the camera profile is applied and the color swap is done. Apply white balance.
From there, LR is very good at making a sky selection, so I could tune up the blues. The work was about 5 clicks of the mouse, under a minute of processing.
I was so excited I didn't even work on the grass or foliage.
Highly recommended! Let me know if you try this method.

Thanks for the info Ari. I'm always interested in a new way to do things. I'll look into it!
That's great stuff, Ari! I'll definitely look into it.

Good luck, fellas. It took a few minutes to create the four LUT profiles.
The accompanying video instructions are clearer and more up-to-date than the blog instructions.
