>>3970195>and no, DXO don't use a 50% figure, they use a 0db figure, ie, there is no signalHoly fucking shit, you don't even understand dB and yet you are posting about dynamic range measurements???
0dB is NOT "zero signal". A positive dB means signal is stronger than noise, and a negative dB means signal is weaker than noise. 0dB is literally the cross over point where signal and noise are each 50%.

>WHICH IS TYPICALLY WHEN NOISE BECOMES MORE IMPORTANT THAN THE SIGNAL "More important than" pretty clearly means >50% of the total.
>THAT IS, A SIGNAL-TO-NOISE RATIO BELOW 0 DBIf 0dB = "no signal at all" then there could be nothing below 0dB.
