Another limit is quantization hwen the signal is digitized. Say we have 14 bit depth, that means we have 2^14 levels of the brightness for whole the dynamic range of the sensor. If I use simultaneously two ISO levels, say 100 and 200, the figure shot with ISO 200 will overflow the INT14 values but I will have twice more levels in the shades. All that applies if the ISO amplification is done prior/during the digitization. If it is postprocessed, there is no advantage. | |
