... and Beta video recorders were superior to VHS. It's not always the best that survives.
Agreed. The archival quality of film can be quite remarkable and to me is a nice "feature".In my experience, this is one of the reasons for using film that a lot of people understand. When I say "you can leave the negatives in a shoebox for fifty years and then someone finds them in the attic and they're still good", that makes perfect sense to almost everybody (the exceptions are the ones with an excessive faith in cloud storage).
Pity about that C-41 exception---it's one of the reasons I don't shoot it much. I think I remember, though, PE saying that the longevity of modern C-41 materials was enormously improved; not to Kodachrome levels or anything, but enough to make a meaningful difference in terms of the transgenerational shoebox.

Yep, film is very archival. The one caveat is that it's archival if you shoot "real" B&W film. I was rummaging through a big box of photos and negs from 12 years ago and had a very unpleasant surprise. Most of what I was shooting back then was either color film or that C41 B&W stuff. The negs had faded so much I had to throw them away. Ditto for the cheap prints Walgreens had made for me. Now I shoot nothing but Tri-X and print my work on fiber paper, so no more of that nonsense.
Even if, in theory, your digital files (be they cloud based or not) will be perpetually accessible, there are a thousand human factors that can get in the way. In my daughter's case, she admitted that she couldn't even recall her MySpace user name, and she no longer has the email address she had at the time, so password recovery is probably not possible.
I was having a conversation with my oldest daughter over the weekend. She is a young mother with two little kids. All of her photos are digital. I highly encouraged her to get prints made and put them in albums.
"Its ok...I have everything on Facebook and that's secure" she said.
"Can you still log in to your MySpace account?" I asked.
Point taken.

The long term stability of color negative materials is questionable. Fortunately, faded negatives are not hard to correct when scanning.
First we need to look at the test methods the Henry Wilhelm discusses in the link that John Shriver provided. IMHO, the tables that report the "Days necessary for a 20% loss in the least stable image dye" are worse than worthless. They are highly misleading. They only thing they are good for is predicting the fading at 144 F (or whatever temperature used in a specific test). The results that are highly useful are the "Estimated Years of Dark Storage for 20% Loss of Least Stable Image Dye". See the tables on pages 202 and 203. For these predictions, the film samples were subjected to a variety of high temperature treatments. The dye fade rates are extrapolated back to room temperature. These tests aren't perfect, but there is a huge body of testing that establishes these predictions as the best we know how to do.
Results: The problem with C-41 materials is nearly always the yellow dye. Kodak C-41 films are typically predicted to last 35 to 65 years under these conditions. By comparison, Kodachrome is predicted to last 185 years while Ektachrome is predicted to last 220 years.
I quite often want to write people letters, however I agree; it takes too much precious facebook time to find a pen and write someone a letter.
Digital data storage is one of the under-exposed (pun intended) topics of digital media. It's not news that magnetic media will suffer dropouts. It happened with tape, and it can happen with hard drives. Usually, I hear of hard drives dying due to other issues, bad sectors, etc, but there is a solution, and it takes a bit of planning.
I have 2 copies of everything, on-site and off, that I constantly migrate forward onto new hardware every year. No, I don't sample every file to ensure that there is no corruption loss, but I do sample a meaningful percentage.
So, I budget an extra $1k every year for storage, and I update the media with newer, usually larger, devices (hard drives currently). I don't use or rely on cloud services, because really, I have almost 2tb of data and that will just never make it to or from any cloud service without additional costs.
I'd rather have digital color stored correctly than forcing myself to only shoot black and white film. (Note, I still shoot a lot of 4x5 C-41).
Future Last Wills will have to have your passwords.not to be morbid, what happens when you die? Who is going to take over all that maintenance? How can you count on there being someone who is both interested and technically proficient enough to turn all of those digital files into something visible?how will they even know where to start? How can you trust but all of that gear what just get tossed into the bin?
