Honestly, I was just afraid to be. I waited about 6 minutes to
have a prescription renewed… and I couldn't wait patiently.
If I were to venture a guess, (and that's all it is from my small experience with digital) I would say you shot those with a D3s or a D700 judging by the fine film like grain in the background, (which I like).
These were shot with the D810 and the luminance grain, of
tubular type, was Capture One converter generated.
I never owned a D7xx!
The D3S, otoh, is my go to camera for low light conditions.
