Originally posted by pingflood At least with digital you CAN make backups quite easily. Sign up with mozy or some similar online backup service and it's entirely automated and your backups are offsite in case your house burns down or something. With film you have ONE original and that's it. I love film but there's no denying that digital while taking a little more effort is easier to preserve pretty much permanently. Once a decade or so you may need to copy over the images to a new format or something, but honestly, how long does that take? A few hours every ten years? Something to be said for that.

It's a toss up, but I think film still has the edge. While a small amount of images may be easier to manage digitally, as time and size of archives increase the issue gets seriously compounded. If film is properly stored in a dark cool/cold place it should last a very long time. Color film not as much, but B&W can potentially last hundreds of years with very little user interaction. Film can also be digitally archived and is human readable.
While I agree it may not be so tough to transfer hundreds of digital images to another format, it won't be so trivial to do so with a lifetimes worth of images numbering in the thousands or hundreds of thousands(for some). It's not as simple as changing the file extension, the files need to be opened and then saved as another format. This may not be a big deal for 5mb jpegs, but what about .tiffs that weigh in at 100+ mb each. These files will only get bigger as the megapixel race continues.
If we only shoot/store Jpegs, then we've already started a chain of bit rot. We've lost information the moment the shutter was released and will continue to lose more as the file is saved to another format, particularly if it's a different lossy format. If we save them in a lossless format, how long does it take to transfer gigabytes or terrabytes of data to an online archive? Once it's there, we have two or three different places holding our files; That's 2-3x as much work when we decide to change the format 5-10-20-30 years from now. It continues to steamroll as time goes on. Bigger files, more places, more formats, different storage devices. Who's to say computers will be anything like they are today, 50 years from now. Will a hard-disk that's sat dormant in the attic 20+ years still work? Can it be plugged in and read by modern computers of the time?
That's the big problem I see with digital archiving. If we're vigilant in maintaining it and willing to pass the torch and train the next generation in maintaining it, then it can potentially last a long time. In reality, most people don't take the time to properly back-up or store their images, be it digital or film. If it's neglected, I'd say film has a better chance 50 years from now than digital. It may be faded or barely left on the film, but a great many digital images won't even exist.
Anyway, I believe like all things, there are pluses and minuses on both sides. I just feel that film has potentially more pluses with regards to archiving.

An interesting read, even if it's beyond the reality of what a normal photographer would be willing to do: The

.pdf that the article talks about.
