This is for Nord/Troj:

You are both saying a "properly exposed" shot at ISO 6400 will look the same as one properly exposed at ISO 100.

Shot 1: 1/8000, ISO 6400, F/8. Camera metering was dead center for exposure.

Shot 2: 1/100, ISO 100, F/8. Camera metering was dead center for exposure.

Does anyone think these shots look identical?

You did not get the point at all!

What I say is that using the same exposure (that is: the same amount of light hitting the sensor) the end result will be almost identical!

1/8000 sec and 1/100 sec at f:8 is NOT the same exposure!

If you use 1/8000 sec and the same aperture setting for both pictures, you will get the same result after processing the raw files. Sure, the very dark ISO 100 shot must be brightened very much at post processing. Still, both pictures will show the same amount of shadow detail and noise.

This is what fixed sensor sensitivity and ISO free raw files is about.
