Rather than a 'disease', how about another 'effect' or tool that can be used to enhance certain image-qualities or moods.

Since I'm more a visual/spacial learner, I'm having a difficult time getting my head around this scientific description.

But I would recommend folks experiment with their own camera's ISO settings and get to know the limitations of their equipment, that way, when different scenarios arise, they have a better grasp of the correct settings.

I tried using NIK Collection's Dfine2 but didn't like the look it created, then I tried using a high-pass sharpening filter in Photoshop, but that left an aura of heavy noise after using a layer mask to remove sharpening from background elements. I ended up going back to Lightroom and tweaking there.

I can't speak with much confidence on the 'why?' as to the technical differences in high-ISO performance between the D750 and D810 (which was released a few months prior), aside from them being quite similar, with the D750 seemingly taking a lead by ISO 12'800. After a bit of reading there are people who believe (all else equal) larger pixels/less dense MP count means better low light performance. The counter-argument to that seems to be that pixel size is irrelevant, for if you compare images at their native resolutions, the higher MP will be noisier, but scaling the 36MP down to 24MP they will have very similar noise performance.

Yes, very good noise control at that high ISO. Some great potential for fast shutter action.

Colton, not to get into pixel peeping, but I believe your D750 has a 24mp sensor. Which isn't high for a full frame format (unlike the D800 e.g. which has a 36mp sensor), and I understand this gives the pixels a better light gathering size than those sensors that are crammed with a higher pixel count.

Is that what contributes to the 'high ISO, low noise' capability of your shots?

I agree with Jana. Are you using a de-noising program, Colton? Great shot--antennae everywhere.
