DR has nothing to do with a crop factor?

BTW that's sexy looking glass.

From an audio standpoint, the minimum levels you have shown as "dark noise" are what we call aliasing. This is the reason we add what is called dither when we go from a higher bitrate to a lower bitrate. Dither is the process of adding a very small amount of almost un-perceivable noise to the signal. This pushes the signal to a level above the minimum threshold no matter how strong the signal is. This is also similar to the bias carrier wave that was used on analog tape machines.

Why is it not possible to add un-percievably small amounts of noise to the bottom range of electron sensing for the purpose of pushing the signal into a range the bit depth we are working with can understand? You could also get a better signal from the ultra top end by a type of limiting or compression of the very top of the electron range.

In audio, the best detail is found when the signal is close to maximum. I would assume this is also true when capturing light. If it is true, then the ultimate future for video is increasing bit depth as the time scale is already set at frames per second. In audio, the samples per second also have room to increase, but in video its not that important. So, once the physical limitations of the sensors are bypassed because of technology, expect to see a bit depth war that does not conclude until the bit depth represents a level of sensitivity hundreds of times more dense than human perception. This is because human visual perception is affected by things we cannot perceive... just like in audio where human audio perception is affected by frequencies that we are unable to perceive. This is also why the music industry is bullshit. The quality level they give us is going backwards.

You are right, I miss-wrote. But you also have acknowledged that it is possible to add dither to a video pixel. This goes to show that the bit depth is most important aspect, and at current standards is well behind what it should be. I suspect that in 20 to 30 years we will have bit depths in the 64 to 128 range, and this will certainly allow dither to function like it should in video. Hopefully audio will also catch up. If the world enters a dark age period due to currency collapse, this won't happen however which is what I am concerned about now. On a side note, silver makes excellent transfer wires for electrons and also makes excellent store of value for real savings in troubled times. And its so cheap now.

What I got out of this.

Beer is good.

More Beer is better.

If I let the beer sit long enough I won't have to figure out what Saturation Capacity means.

What I still can't figure out after looking at the pretty pictures.

So if I get a bigger glass does that increase my dynamic range?

If I have a bunch of flat beers, dark beers, and light beers and mix them all together and then somehow extract the flat and dark beers will I end up with a better light beer that has more dynamic range and much greater signal to noise ratio?

LOL
