nikon – Where are these maze-like noise patterns coming from in this tit photo?


This is the RAW image cropped but otherwise untouched, saved from Nikon’s own ViewNX-i as a 100% quality jpg.

It shows some hint of interference, as we’re right down at pixel-peeping, but not the extra ‘crunch’ darktable seems to have added. The colour fringing is vastly reduced too.
It has, of course, had the snot cropped out of it – it’s down to 493×362 out of a 6000×4000 original.
I’d really suggest you need a longer lens for birding ;]

I’m going to go back to my usual stance on this – don’t use 3rd party software for initial processing of Nikon camera images.
