Very weird blue light grain / noise w/ Tamron 17-70mm sony a6000

Looks like all those pictures have been taken under blue led light. That kind of light is difficult to handle:

  • it’s very monochromatic, so the colour is out of gamut for most colour spaces;
  • there’s an overdose of UV in it, for which the camera sensors are sensitive, but not our eyes; that falsifies the colours wrt what we see…

See This episode of “Editing moments” by @s7habo where he shows a way to handle this. Perhaps post one the images as a play-raw (if you have the raw files) so others can practice on them?

In summary,what you show is not a problem with your camera, and even less with your lens (and what do you mean with “bad profiles” concerning that lens?)
