LOL nice Dan.
Anyways to show my point with LR NR and how it does effect the purple boarder I did a quick test in my computer room to show what's going on. Here are some images with and with out LR NR, I used default values when on (25/50):
D800E 24-70mm f/2.8 @ 70mm f/4 1/250th iso 25,600 for both shots in manual mode. WB adjusted to the same settings.
Whole frame with no NR at OFF:
Whole frame with default LR NR at ON:
Crop from image with NO NR:
Crop with default LR NR:
As you can see LR leaves more of a purple tint in the black box area, think shadows or dark parts of the frame.
Now to test what a few were saying that under exposure can case this to be worse, I took another shot at a little slower of a shutter speed, all other settings the same:
D800E 24-70mm f/2.8 @ 70mm f/4 1/160th iso 25,600 for this shot in manual mode. WB adjusted to the same as prev. image:
Exposure pulled down by 1/3 a stop in LR No NR applied:
Now with color NR at 20/100 and luminance at 10/50/0:
So it seems if you have to use the higher iso's, best to over expose a little and pull back in post as it does help.
