Wire's comments are spot on. The increase of effective bitdepth is a useful measure against quantization artifacts like banding (mostly improves artificial imagery devoid of noise, e.g. single-color gradients, and gives headroom to loose some levels due to adjustments like 1D calibration curves). The (in practice less relevant) increase in numbers of possible "colors" (shades) is just a resulting side effect. Cheers, Florian. Am 06.01.2020 um 14:46 schrieb Roger Breton via colorsync-users:
Wire,
You wrote :
However an RGB / YUV display that processes 1 billion colors on its interface may reasonably be expected to produce 1 billion quantifiably different stimuli on its face
That's the whole point of the thread, isn't it? I remain skeptical. Stick with 16.7 million colors for a moment : can you point to any article that ever documented this?
