Quote:It more like just adjusting EV in the RAW processor, ending up with a normal DR (lets say 7 stops, normal contrast, or 5 stops, high contrast) in the end product.
So yes, the film itself has a "high DR" for exposure, but the developed film does not. It is like a window of limited DR gets moved along the wider DR latitude of the undeveloped film, and where that window stops depends on the development time of the film.
I'd have to check. From what I remember it is really up to 10 stops or even slightly more, but I'll need to find the stuff I have on this at home, which currently is difficult to find due to the basement flooding we experienced last year - everything is stacked in a way making it unaccessible, and I expect that I will only have access to thsi stuff again by the end of March or thereabouts. I have some Kodak pro documentation on this stuff somewhere.
The last few stops, at the end and at the top, really only have a shortened height on gamma curves, but they are there. If you are talking about the straight part of the gamma curve, you are correct, that is about 7 stops, maybe 8, but even Ansel Adams worked with a DR of around 10 stops (Zones 0 to 9).
Kind regards, Wim
