>>3892878>How can you explain the -x dB levels of 0 is the minimum? How fucking simple are you.Noise floor is defined by the minimum ACCEPTABLE (hence why it's a subjective choice) SNR level. Decibels are logarithmic, under 0dB means noise is overpowering the signal (i.e. there's more noise pixels than signal pixels). If the ratio is 50/50 you get 0dB.
Dynamic range of the sensor is defined by the amount of stops between the selected noise floor and saturation.
>examplesThere's one above lol, the sky at night. Look at the building visible in deep shadows at ISO 2000

But hey, take this test scene done by a researcher.
