So I'm not convinced that film outstrips digital in resolution terms. Or if it does then it won't for much longer.
It's not simply about resolution; it's about the type of resolution. It's difficult to explain to people who might not see/hear the difference (I don't mean for that to be or sound condescending); but there is a difference that exists between analogue and digital recording/reproduction (light and sound) that is, perhaps, insurmountable I've looked at example images from a D3X and, for all their impressive clarity and precision, there is still, to me, something decidedly digital about them. Perhaps it is that impressive clarity and precission? I'm not talking about whether or not one is better/worse, merely that, for some, analogue reproduction is obvious to some people and, of course, that some will find this preferable. It is is the qualities of analogue that I'm talking about, not an objective measurement of quality (standard?).
By coincidence, I was doing a Google images search for Ilford XP2 film this afternoon and the strength of the images that came up was striking. Even images with bold contrasts have a smoothness to them, a blend of tones, that seems to be unique to analogue. I sometimes wonder if, in very simple terms, this is down to the square edges of pixels, as opposed to the essentially infinite nature of analogue. There is a similarly natural feel to music recorded on high quality analogue tape, which, of course, has numerous disadvantages to digital recording equipment.
Many percussive sounds are reproduced much more favourably using analogue equipment. By favourably, I mean that they sound closer to how our ears (generally) perceive them. It's not uncommon for studios to use tape to record drums, then digital to record everything else, all in order to keep the percussive tone of the music more lively and natural. There is obviously some loss when the finished mix is digitalised. To take an example, the White Stripes' Icky Thump album is entirely analogue in recording and mixing and sounds quite sublime on vinyl - even the harshest of contrasts are able to blend smoothly. I'm not saying for a moment that I could always differentiate between analogue and digital, but my eyes and ears do seem to quite good at picking them up. In the simplest of terms, analogue is more comfortable to perceive than digital, if that makes sense.
There is a habit of throwing the baby out with the bathwater when it comes to new technology. Film/digital; tape/digital; valve/transistor all come to mind. One of the main advantages of digital is that it does not suffer from the same noise that analogue does. CDs sounded 'high quality' when they came out because there were no cracks and crackles that we were used to with vinyl. This difference was deemed to make digital 'better', without paying any attention to the fact that other aspects of the sonic reproduction had in fact changed. You might be surprised to know how much recording studios spend on analogue emulators in an attempt to recreate the feel and warmth of tape recordings. I mention all of this because sound recording is further down the digital road than photography, especially in the consumer market. I honestly don't think that digital can look or sound the same (same; not necessarily better/worse) as analogue, and yet that is what is being strived for in the digital world. So the question has to be: why? Personally, I think that it's because a good analogue representation is closer to the way the human eye/ear would perceive the original - with infinite blend between different light/sounds.
(pardon me that all of that is a somewhat rattled off; I'm doing a couple of other tasks at the same time this evening)
