"Dynamic Range"
'Once the almighty reason to shoot with analog film over digital, dynamic range is no longer the huge debate it once was in the past. While the dynamic range of an Image is a complex process that takes into account the sensor used, the type of file compression, and other factors, digital is ultimately winning against analog film.'https://petapixel.com/2015/05/26/film-vs-digital-a-comparison-of-the-advantages-and-disadvantages/And while digital cameras "may" be more profitable to make, the consumer is saving by not having to buy consumable film.

Quoting from that article:
"According to research carried out by a team of four industry experts, it was found that medium
format film has a potential to capture a jaw-dropping 400 MP photograph, however, after digital scanning,
resulted in a resolution of 50 to 80 MP."
Which is a reason not to digital scan,
not a reason to reject medium format.
And if medium format is "jaw-dropping", large format will take your whole head off. Quote:
"Another test, also conducted by Roger N. Clark, noted that larger formats such as 4×5 inches can
capture 200 MP equivalent photographs after being scanned"
What he says about dyanmic range is "Ultimately digital is winning against analog film"
--i.e., it is outselling film. Obviously, that's true. And Cold Duck outsell Dom Perignon--
so it must be better? Wrong.
Quote: "A release by Kodak showcased that most film has around 13 stops of dynamic range.
Today’s modern digital cameras all average around 14 stops of dynamic range, with high-end
units such as the Nikon D810 reaching almost 15 stops. Film continuous to deliver incredible
dynamic range, but today’s digital technology can easy match it."
Wait a minute: "most films" -- what the heck is that? He's talking about
color film--
including color slide film! Edward Weston did not work in Kodachrome. Ansel Adams did
work in color, but burned all his color negatives.
He cites no sources for his assertion that "digial cameras all average around 14 stops
of dynamic range." So I guess her personally bought every digital camera made, took it apart
and tested the sensor. Or maybe not....
Actually, Nikon only
claims 14.7 stops for the D850 (per Nikon specification ont he
Nikon web site). But Nikon offers no independent testing or evidence of any kind that
I have seen. So please somebody e-mail this article to Nikon, so they can update their specs.
From the very beginning of commercial digital cameras, manufacturers have exaggerated both
the resolution and the dynamic range--just as the auto marker used to exaggerate gas mileage
(until Congress regulated it) and drug manufacturers used to advertise exaggerated claims
until it too, was regulated. "Geritol cures tired blood." No it doesn't.
There are articles on the Internet "proving" that the Alkaline Diet cures cancer, that the earth
is flat, and that Elvis is alive. Part of being a smart consumer is not believing everything you read.
This "article" wasn't published in any periodical, let alone in refereed science journal.
Who knows what the "editorial standards" of PetaPixel.com are, if it fact checks articles,
or if even has an editor. The name "PetaPixel" suggests that it is not impartial on the
subject of digital vs. film.
The author does not offer any reasons or science to support his conclusions, and the "authorities"
he cites are either suspect or untraceable. The "release by Kodak" is never identified--no citation.
So there is No way to verify the information.
The author himself offers no qualification, nor does he say who paid him to write the article.
He doesn't even mention ever having used a camera. It's a typical hack job.
