So Art quick question thats been perplexing me:

So does the linear to log encoding process occur based on the sensor’s already made linear encoding of the image? Or are the bits distributed logarithmically directly from the sensor’s voltage values?

If it’s the former, it would seem to me the linear to log conversation would involve essentially making up bit data from thin air in the shadows, since the linear base image has so few bits devoted to the shadows.

That’s the exact same data encoded in log format. It’s quite different, isn’t it? NO!!!! is exactly the same curve and same data registration.. The first Graphic has a linear scale the second a logarithmic scale.. In fact n.4 is close below the 100 value in both grapics!!!!!

I understand what you are trying to say, but your explanation is completely incorrect.

The Fstop scale must be logarithmic, not bit depth scale!!!!
