>>4220568It’s the range between full well capacity and sensor noise. To increase DR you have to improve one or both aspects of the sensor.
Keep in mind that while FWC is a hard line, acceptable sensor noise is somewhat arbitrary. That’s why DxO and PtP yield different values for the same data. Scaling and NR alter the result for any given test as well.
So a claim of 16ev may represent a real improvement, or simply the parameters of a specific test.
