Bill and GLuijk, - excellent illustrations!
Bookmarked the thread.
Regarding above mentioned observation of "film vs digital", I still doubt that it could be accessed by "usual" DR measurement. It’s probably more a question of what happens: during and after the DR is exceeded.
With increasing exposure, digital color clips per Raw RGB channel. So after a transition period of single channel clipping and corresponding hue shifts we reach ultimate 255 white. With film, things appear to be different. With increasing exposure, luminosity differences seem to get lost first. But the color itself, e.g. the yellow-orange hue of the sun globe, seems to survive surprisingly long before everything is burned to white as well.
Admittedly, this is just a subjective impression
And a bit of topic anyway.
