Question on noise...

Hi All,

Thiis is probably a dumb question... but how is noise produced in a photo. I am using the D850 for past couple of months now and noticed that under the same ISO and same focal length I get some cleaner images than others.

I understand noise is produced by the sensor sensitivity based on the ISO setting, still why the noise is not constant when the ISO is still the same ?

Thanks !
