Very nice essay, which I agree with in full.
The medium is the message. Digital is immediate - let's see what just happened two seconds ago. Film - let's open up grandma's photo album and see what was goin' 50 years ago.
I seriously, SERIOUSLY doubt that anyone - anyone's kids will be viewing "old jpegs" their dad took. People (general public) don't print digital images very often - it's a different medium, a different message...
immediacey vs. timelessness.
Part of the reason I went back to film after think "ain't digital grand" for a couple years is this very reason. Film forces me to make prints.
Again - in terms of emotional impact, I point to TV. Even though it's much, much cheaper to shoot digital, and the results are certainly acceptable, dramatic television is almost entirely shot on film even though it is easier and would cost far less to shoot digitally. Digital is left to cheap reality TV shows and sitcoms or as a way to view a scene that was shot on film - immediately. It is also often transfered to digital for special effects - digital manipulation and matte shots, then back to film it goes.
Filmmakers know, "the media is the message". Film = emotional impact, beauty , dream-like, it "tells a story", expensive but worth it. Digital = immediate, fast, easily manipulated, cheap.
I school, where I post student pics, I get this all the time. One recent comment, "I forgot how good film looks". One guy asked me for a recommendation on a digital point and shoot (I recommended a mid-range Panasonic). He didn't like it. He saw the images I made with the Zorki and Summar (which cost 1/2 as much as the Panasonic) and said he wanted his pics to "look like the ones I take". He's looking at Zorkis, GSNs, C35's. Another employee came in with her baby, she made a bee-line to my office and asked if I could take pictures with my film camera because "they look so much better than the digitals, and she doesn't have many prints". Shot a roll - super fast, with ambient light with my GSN - no flash needed, she absolutely loved them. One student - an engineering student, was walking around with a broken Sony DSLR. I happened to have taken an 8x10 portrait of him in class. He shook his head, and said he never got a pic that looked "like that" out of his broken $1500 Sony DSLR. No flash, no whirrling auto focus motors, no "pre-flashes", no giant zoom lens. Natural light, and a near silent "click", no asking people to "hold a pose". He asked (and several others) if they could have their portraits. Last weekend my wife overheard a debate with a couple relative who were floored I was shooting with a folder camera (Iskra)... they shoot digital point and shoots and a Nikon D70. When they refused to believe that a medium format film "blows away" their little point and shoot, I knew I was arguing with... (I'll be kind). My wife overheard the conversation and said my pics are 1000 times "better" than when I shot digital and there's "no comparison" between digital and film.
She's not a photographer, nor am I. I'm a rank amatuer. Nor are those who want the prints I make at the school where I work, or want to know what kind of camera I use. I don't "sell" film photography to these people. They're regular consumers who see the difference and wonder why they never get that "cool blurred background" and "almost 3D look" from their digicams.
The media is the message.
