Seriously though, there is a lot that you can learn from shooting film,
though most of it could be applied to shooting with a digital camera.
There is nothing preventing you from taking care to set up each photo
with digital, and then move on after it has been taken.
He talks about the dynamic range of film, and to my surprise Tri-X
might exceed the dynamic range of the K-5 at ASA 400
http://www.dantestella.com/technical/dynamic.html
Item Numeric Stops of range in subject
Polaroid Sprintscan 120 scanner 3.9d Depends on the film being
scanned.
Tmax 400 film (0.58 CI) 3.4d 19.5 stops
Tmax 100 film (0.58 CI) 3.0d 17 stops
Tri-X 35mm film (0.58 CI) 2.4d 13.5 stops
Kodak DCS Pro 14n digital 69dB 11.5 stops
Fuji Finepix S3 digital camera -- 10 stops (estimated)
Tri-X 35mm film (0.75 CI) 2.4d 10.5 stops
Nikon D2x digital camera -- 9.5 stops (measured)
Typical LCD display 500:1 9 stops
Kodachrome 25, 64, 200 (1.4 gamma) 3.7d 8 stops
Ektachrome 100 (1.4 gamma) 3.4d 7.5 stops
Human eye (no iris change) 150:1 7 stops
I will say that the kinesthetic experience of using a film camera is
different than that of using a digital. In comparison, most digital
cameras feel nearly disposable.
I nearly had to resort to a barf-bag on reading that article, he
sounds like a reformed smoker or a born again...
In the case of latitude on film vs digital my theory is that people
are far more likely to hold back exposure to prevent burning out
highlights in digital media because it's so obvious, especially when
working in colour. In the case of B&W film you can burn baby burn and
even at max density there is still a relatively soft transition into
the normally exposed areas and of course there are no giveaway colour
shifts. I'm betting that the Leica M-Monochrom would seem a lot more
"film like".
His numbers are whacked out. Tri-X is hard pressed to give more than a
10 stop range, and you had better be prepared to do some really
deliberate exposure and development to get it to 10 stops, much less
anything greater, and there wasn't a Kodachrome made that would give
more than a 6 stop range.
The K5, with it's 14 stop range is comfortably better than ANY colour
film ever made, and can only be outdone in dynamic range by B&W film by
extreme over exposure/extreme under development. N-4 or N-5 development
will hit close to 14 stops with FP-4 (been there, done that, have the
picture to prove it), but you are exposing the film at something like
ISO 6 and then giving the film a reach around to get it to cooperate.
