Response to Tonal range of Chromogenics compared to trad. B&W

HP5+ shows a fairly straight curve shape through 15 stops (the limit of my testing) while T400CN has a very strong shoulder.

So...HP5+ definitely has a longer tonal range in that it doesn't drastically compress the highlights.

Otoh, more highlight detail would be rendered in a print from T400CN, although at low contrast.
