I revisited this sighting of a female leopard at night from a quick trip to Singita Sabi Sands in 2015, cause I wanted to apply Adobe Lightroom's new Denoise AI to it...
The new addition works quite well and you can see effects on IQ at 100% in real-time to decide whether you want to dial it back or rather revert to the old manual NR module.
Techs:
Nikon D3s
Nikon 500mm f4.0
f4.0 | 1/160 SS handheld | ISO-12800
Spot-light used off-subject for some illumination
Pretty much FF, minimal crop for rotation
