The scene may well have all 14-15 stops of light in it........the eyes cannot see all of that and nor can printers resolve it........the -14 stops of DR in the deep shadows need to be raised to become -12 stops.........and the upper level needs to brought down by -2 stops to stop bleaching......

.......this now gives a final image with a DR of 10 stops overall....you need the DR curve to be non linear........while including all the image graduation of a 14 stop image.....

.......which most printers can handle!
