Thanks Steven!
I guess I meant the bitdepth thenSo more discrete luminance values for a given pixel means the dynamic resolution is higher but not necessarily the dynamic range. Or is there a maximum luminence difference you should not exceed between two values because it would result in a bad picture quality?
I don't know what you mean by "dynamic" resolution.
Indeed there is a maximum allowable step between luminence values that one should not exceed, otherwise you get banding. And it's a log-type function (that is, at higher lumen values, you can have a larger jump before detection).
Hence you need a sufficient number of steps (bits) to represent those values. Once you get ABOVE that number of sufficent values, you are wasting bits if you make finer gradations.... you can't see them. Hence additioanl bits are ususally used to handle more DR.
