So caveat here, last time I shot fully manual was about 30 years ago. You couldn't change your ISO on the fly, you picked out a roll and that was that.
Now here I am shooting digital and what is wrong with the lowest ISO setting? Searching around I feel like I'm the only one with this issue. ISO 160 sucks the saturation out and tries to push the image towards black and white with high contrast, it feels like. If I tap it up and readjust everything, even just to 200-400, the problem goes away. Any thoughts? Busted lens? Some setting buried in the massive list? Any help appreciated... seems a shame not to shoot at 160 when I've got plenty of light (or is this old B&W film mindset?)
Fujifilm X-T4 BTW.
Edited to show what I mean better: not identical pictures but from the same day, of the same tree.
Have you tried taking RAW format photos and doing a little post-processing (in particular whatever more detailed Histogram or Luminance tools you have)? This sidesteps a lot of functionality that usually guesses right, but can go horribly wrong.
Are you manually setting all three of aperture, ISO and speed? If not, double check what the auto settings of the others are (you should be getting those details in the photo meta data - visible under Properties|Details in Windows, as well as "Live").
