I can discuss facts whenever you want
I do not think I am the one who has trouble to understands facts= DR full well capacity, QE and read out noise+ banding and pattern noise
First of all - all that bolding is childish and unnecessary, it doesn't really help you make your point come through, it just makes you seem rude.
Secondly, stop confusing DR with exposure latitude, DR isn't actually about how much you can under/over expose, especially not about doing it in post-process. Seriously.
