Distorted Reflections
Today's topic - "Archival Storage"
[Note: This is the first installment in a continuing series. Phil and Otto have been writing about imaging for quite awhile now. They are sometimes recognized as their alter egos Randy Fredlund and Joe Manico.]
Where pictures go to die - all the pictures you could never find in yesterday's shoebox.
Phil: A friend of mine brought me an old disk the other day. He couldn't read it.
Otto: What was the problem? Was it a Frisbee printed in German?
Phil: No, No, it was a CD. A 'Photo CD'. He couldn't read the images on it.
Otto: You need to take good care of media if you want it to last. I'll bet he scratched the heck out of it, didn't he? CD's should never be used as beer coasters, unless they provide 1,000 hours of free Internet service.
Phil: No, not at all. It seems that the application he was using did not recognize the image file format. I opened the disk with a different program, and presto! the images appeared. So I converted them to JPEGs and burned him a new disk.
Otto: So life is good! Problem solved. You are once again hero to the common man.
Phil: Well, maybe for the moment.
Otto: What do you mean?
Phil: What happens when the applications no longer read JPEGs?
Otto: Oh come on. They'll always read JPEGs. The JPEG file format is the cornerstone of the Digital Imaging Universe. He'll always be able to read them.
Phil: Mixed metaphor aside, do you mean that they'll be just like the family albums you had transferred to Betamax tape?
Otto: Unfair! That was different. The Betamax is an archaic analog format from the last millennium, and it was not an open standard like JPEG. Other manufacturers decided they would also like to be in the game, so they created the more open and slightly inferior VHS format, which was the winner in the marketplace, for Beta or for worse. JPEG is a DIGITAL open standard format, free for all to use and enjoy. It provides perfect digital copies and it will be supported forever. Besides, if it is surpassed by an even better format I can always convert my files without losing any quality.
Phil: Put down the sitar and stop humming Kumbaya. Which episodes of The Simpsons are you going to miss so that you can spend countless boring hours converting files???
Otto: The Simpsons? Sorry, I need my culture. Maybe I need to have someone do it for me.
Phil: Don't you mean 'pay' to have someone do it for you? When is the last time you paid anyone to do anything for you? And remember, you'll have to convert all your images. When did you start using digital images?
Otto: Including the pictures I downloaded for my essay on accurate skin tone reproduction of lovely subjects?
Phil: No, I mean your FAMILY pictures. You know, the ones you show at family get-togethers.
Otto: Hmmm... That was about 3 computers ago.
Phil: And you still have all your images?
Otto: Well, yeah, except for the ones that disappeared when one of my hard drives died. But ever since then, I've backed everything up to CD. They'll always be there in my 500+ CD image library.
Phil: You sure?
Otto: Of course. My Pictures are safe and sound forever on CDs.
Phil: I don't think so. You've got a couple of problems. First, like with my friend's disk, whatever file format you've stored them in won't be around forever. As new and better formats become available, the old ones fall by the wayside, no matter how popular they are now. Next, there is a media format problem. Have you read any images off 5.25" floppy disks lately? Can't do it, can you, 'cause you don't have the drive.
Otto: You mean like how many bagels won't fit in my old 2-slice toaster?
Phil: Ahem . . . and then there is the problem with the media itself, or "CD rot". Sooner or later, it will fail. Nothing lasts forever, and more importantly, nothing lasts as long as originally thought.
Otto: Are you telling me my CDs are toast?
Phil: Could be. Even if you could access all of your images, they still would be nearly useless.
Otto: I'm guessing you're going to tell me why.
Phil: You bet. Your images will be useless because you can't find the ones you want.
Otto: Huh? I store them all in dated folders. No problem.
Phil: In ten years, are you going to remember the date of the party where you were wearing that lampshade on your head?
Otto: I couldn't remember that party the next morning.
Phil: Let me tell you, 10 years won't make your memory any better. You'll have thousands of images on many, many disks. And you won't even know which disk to look for.
Where pictures go to die - all the pictures you can never find in today's shoebox.
Otto: So how am I going to pass on to my future great-grandchildren that fabulous shot of Pickles and Sugar?
Phil: You want to pass on pictures of food?
Otto: My wife and dog, wise guy.
Phil: I won't ask which is which. You have only one alternative it you want to preserve your legacy. You'd better get it printed, my friend.
Otto: OK, great. I'll run right out and get some reloaded ink cartridges and a ream of copier paper, fire up the inkjet printer!
Phil: And you better rent a warehouse to store all those pictures in. Never mind. Just leave your pictures on the disks. Forget I ever said anything about them.
Otto: Too late. I feel an obsession starting to take hold. What about one of those on-line sites? Those images are on professionally maintained servers, buried in deep underground, nuclear-hardened bunkers. They will be around forever, right?!?
Phil: Yeah and they will happily store your terabyte of snapshots of your dog forever, for free, and the Tooth Fairy will guarantee it.
Otto: Tooth Fairy huh? As mythological creatures go I would prefer one less interested in cash transactions. Any other ideas on what I can do with my digital images?
Phil: Of course, and you may even find some of them useful. The first is the absolutely safest method available for archiving your digital images for the long haul. The data storage technique will last and be 'readable' for over 100 years unless the electromagnetic spectrum or human sight changes. This technique will require some cash and some storage space, but as long as YOU can read, YOU can read these images. Have your digital files printed at your local digital minilab that uses high quality paper and chemicals like the sign in the window says. All you have to do is drop off your brand new gigabyte SD card and your well-worn credit card and say, "print them." Let's say at $0.20 per image and you can on average store 500 digital images per gigabyte that's $100 per gigabyte for image storage. Throw in another buck for a plastic shoebox (don’t use a real shoebox, cardboard is not waterproof) and voila! You have an image archive that will be all but immune to the ravages of time. And if you want to be really safe, be sure to get doubles for storage under Ayer's Rock in Australia. Never can tell when a comet might hit one of the hemispheres.
Otto: Yeah, yeah, yeah. OK but a 4' x 6' print just won't do it. If I get 300 pixels per inch digital prints, and I'm being generous, that's only - uh hold on while I consult my slide rule - only 1.2K by 1.8K. That's too small for my professional quality images. I'm sure that this is fine for amateur snap shooters like you, but I need more resolution.
Phil: I'm sure that you need to have a lot of things resolved. You could print 8x10s, or maybe try my second idea. This technique will cost more and is harder to find but is archival and high resolution. Find a commercial photo lab and have your digital images written to film or slides. Prices will start at least $1.50 per image and climb fast, but the images are eye readable and will be far into the distant future. Once in the future, even if the last film scanner has gone the way of the wooly mammoth, any futuristic wiz bang digital camera with a macro mode will work well as a film or slide scanner. Slides are best, since they are individually mounted and are not "negative." If you choose negatives, spend the extra bucks for index prints or contact sheets to help find the images you are looking for, unless you naturally see colors in reverse. Don't worry about inverting the negative images. I'm sure PhotoShop Version 44.3 will be able to handle it.
Otto: A buck and a half per image!!! I don't need THAT much resolution. Any other ideas?
Phil: The first two aren't good enough for you? Then try this technique, even though it has an uncertain future because it's digital. That's right, use DVD, the penultimate computer and home electronic Über-format. Since DVD is a "digital format and media," it is by its very nature a passing fad. But don't let that stop you. Find the most archival, and quite likely the most expensive DVD media available and write your full resolution images to it or pay your local full service photo specialty shop to do it for you. Now take the DVD and make copy of it. Put one copy in your safe deposit box and put the other in a nitrogen atmosphere hermetically sealed heavy-duty plastic container along with a brand new DVD player. Bury it all in the plot you have reserved at Riverview Cemetery. The plot will cost a few bucks, but even so, this is by far the cheapest method. But it may also be the shortest term. Remember Betamax. I doubt DVD will be the format of choice when reach your "golden years." So somewhere along the way you will have to dig up your container and transfer your digital images to whatever the future digital format is. I wouldn't be surprised if rat brain cells in a holographic matrix become the data storage method of choice.
Otto: Wow. My head hurts. Do you have the Tooth Fairy's phone number?
Phil: Just leave your SD card and a major credit card under your pillow tonight and I'm sure he will call you.

Comment: Hi guys. I read your fun nerds blog entry a while ago, but a recent trip to my parents caused me to look it up again. In the entry you had mentioned the Kodak Photo CD as one of the orphan file formats. My parents are avid picture takers and were big users of the Kodak Photo CD system, and consequently have tons of photo cds with files that we would like to convert into JPEGs. What program can read the Photo CD files and allow them to be saved as JPEGs? - Kathy ---------------------------------------- Kathy, I suppose our comments were true in a general sense, in that the industry has not gone forward with the Photo CD format (.PCD), but not true in an absolute sense. Kodak still supports this format. Although I don't have the software at my fingertips, I'm pretty sure that our EasyShare software will allow you to convert. I also believe that what is likely to be a better option is to use Adobe Photoshop Elements. This program is capable of opening .PCD files, and a myriad of other things that one might like to do with images. If you have any desire at all to modify images, this is the slightly down-featured version of it's parent, Photoshop, which is one of the industry standards. A really great thing about Photoshop and Elements is that you can do batch processing. In other words, you can set up the program to open all the .PCD files on a disk and convert and save them all as JPEGs. Once it is going, go get a cup of coffee. - Phil

Comment: Reba, Don't know that we can help you. Far too many variables could be at work for us to say what has happened to your pictures. Not that it helps you with these pictures now, but the best course of action in the future is to make backups. Multiple ones, even. Or even prints!

Comment: Well I'm a novice, so this was helpful to me. However, it is not the answer to the question that I have. Some Shareware pict. in my collection have started developing zig-zag verticle lines & will no longer open! Message says I "moved or deleted them" which I did not. Help!

Comment: Dude, we got the point after 5 lines. This is similar the music industry. Vinyl to Cassettes to CD's to mp3's. I don't see FLAC or Ogg taking over mp3's just yet. I think things like FLAC are for music purists which is a small minority of the general population. Mp3's are good enough to people, it will be a while before they all accept something different. I think the same with JPEG. Also, off the side, I think with digital, most people take (and save) too many crappy pictures anyway. So, it's a good thing if they get lost. :P

Comment: Dudes, Sumerian tablets have been around for thousands of years and people can still read them. Pretty images at Lascaux- 20,000 years and they still rock... low tech is forever...
