I can see Keira's point, from both sides of the lens.
Something about the subtle difference between looking through the camera as opposed to looking at the camera.
In a studio environment, the operator went through a series of acts and adjustments, light meter, lights, camera settings etc; between every change, all the attention was on the subject, not the gear.
Even in 35mm slr or rangefinder photography, I would spend a lot of time surveying the scene, peeking above the camera. Even better were hasselblads and rolleis, especially on a tripod : you glanced down to check composition and focus, looked up at the subject to choose the moment : you looked your subject in the eye while taking the shot.
Digital cameras demand more attention : more knobs, more functions, histograms, some don't even have a viewfinder : you have to look at them from arms length to see what it frames. With an slr, or a rangefinder, your eye is in the lens, or just next to it, a compact digital, however, sits right in the middle of the foreground of the scene you are trying to shoot : you look at the camera, the camera looks at the scene, which is beyond the camera.
Digital can mount up to a tremendous amount of variables : shutter speed, diaphragm, Iso, neutral density filter, auto-focus mode, etc. With film, ISO is locked with the film, only three variables left : speed, opening, focus. Everything else happens in the scene, most of my attention goes to the subject. Digital 'demands' that I check at least four variables plus a histogram, I spend more time looking at the camera, and the subject almost feels like an afterthought. For me, juggling three variables is a feat. Having to handle four or five is a little too much for my idiot brain.
A strange thing : with digital, even though the feedback is immediate, there is a disconnect. Film, even though gratification is delayed, allows for a much more direct experience.
Sorry if all this is obvious and boring.
