Roger's results are *correct* and, on top of that...

...they are CONSERVATIVE, and manageable.

The tonal range where Digital destroys films is in the shadows, especially in today's best-in-class sensors with fairly high signal-to-noise ratios and basically photon-noise limited, without mentioning how beautifully aligned and uniform are digital's density-response curves when you dive in the shadows, as opposed to the mess provided by Film, especially at anything above ISO100.

You can pull out about 11.0-11.3 from an 12-bit A/D loaded on a EOS 1D-class cam or 5D, for instance, and keep up a good chunk of that DR even on high-ISO.

Anything else you read on this subject is pretty much non-sense, or simply put, incompetence with digital pipelining/workflowing.

Enjoy!
