Re: Banding : Lightroom related?

Extreme increases in luminance (5 EV for instance) can reveal artifacts when the sensor's analog signal to noise ratio is extremely low due to high ISO settings. ISO 6400 underexposes the sensor by 5 stops compared to the base ISO (300).

Then you amplify the noise by increasing the shadow region brightness by another 5 stops.

Is anyone surprised artifacts can be seen with a 10 stop disadvantage compared to an optimal exposure of the same scene at ISO 200?

Fujifilm just can't produce a proper sensor and data stream that is artifact free when abused by 10 stops.
