Do Digital Photos Endanger History?
Ant writes "Experienced photographer Jayne West wrote her degree dissertation on the
historical impact of digital capture. She
argues that the use of digital photography in
news reporting means we could lose a
valuable pictorial record of history." Much of her argument seems weak to me (precisely because digital photography allows the instant culling West talks about). The digital storage itself, though, perhaps ought to make us nervous.
The ability to instantly cull photos that digital photography allows might just result in the loss of a significant portion of our pictorial history. Some of the greatest photojournalistic coups of all time were accidental ... things caught in the background of a photo that were only discovered on later examination ... many of these priceless records would have been lost if the pics they were found in could have been trashed instantly because "the light isn't right" or the composition sucks.
As for concern about digital-only storage, this concern is well-founded too. How do you recover the data when readers for the media are no longer available? Seen any 8" floppies lately? How about 5.25"? The cost of transferring terabytes of archives to new media has cost the loss of literally TONS of data. Film (preferably black and white, or separations on black and white film) is the ONLY suitable medium for archiving image data.
utter rubbish
When I take a digital photo, it goes on a Sony Memory-stick. I copy it over to CDR.
The average lifespan of a CD is about 20 years. Slightly less if you use CDR.
We still have some of the very first photos taken, about 150 years ago... around the time of the end of the civil war. They're in pretty bad shape however. The ones that are best preserved are kept in airtight storage. Nobody ever gets to look at them. Only their copies... And with each successive analogue copy, even with the most loving attention to preserving the quality of the original, a little is lost.
Twenty years from now, if I'm dilligent, I can copy all my CDR to Super-DVDR or whatever. I'll have perfect digital copies of everything I kept before... if I was dilligent and made backups in case of fire, etc.
Twenty years from now, the only format we'll be able to see most of the ancient photos we have will be digital. Those who own them will no doubt be dilligent in making sure both the originals and the digital copies are kept secure one way or the other.
Fifty Years from now, I can make copies of my Super-DVDR to Quantum Storage, or something similiar.
Fifty Years from now, those ancient photos will still reside in a digital format, probably alongside my digital photos.
Even when the copies of the copies have broken down, if we're careful and follow data saftey and purity rules, we'll still have digital versions of
*all* the photos. The question you have to ask yourself is that digital storage the wave of the future, but can we, as a historically-minded society, be dilligent enough to make sure that our data is always secure?
Off-site backups on the moon, anyone?
The next Slashdot story will be ready soon, but subscribers can beat the rush and slashdot the links early!
I sincerely hope that this was an undergraduate thesis and not doctoral-level stuff. I sure wouldn't want to have to defend it! :) It seems not only is Ms. West presenting a weak argument, it seems that an application of common sense would suggest the exact OPPOSITE hypotheses to the ones she chose to defend. Allow me...
/. is harping on this for being inaccurate, but I'd go one further. Digital "film", regardless of media type, is SO cheap and so reuseable that the digital photographer takes MORE pictures, not less. Hey, they're free, right? Click click click click click. Argument inverted.
/. today - I'm surprised I didn't have to pay to download the PDF from BBC! :)
Issue #1 - But, because of storage issues on the camera, he will have to delete some of those images as he goes along. I know everyone on
Issue #2 - A whole collection of material, that may well be far more interesting in the months and years after the event than in the hard news context, is being lost at that stage. Lets imagine photographer A is old-school SLR-boy, and he took 1000 pictures of a given news event. Photographer B is techno-girl, with her 7-bazillipixel Sony Megivica. She takes 500 pictures, because she was told by her ill-informed friend Jayne West that she should delete half the ones she takes.
Now imagine this news event turns out to be worthy of going thru the "dud" pictures afterwards. What is more easily examined after the fact - 500 digital pictures (click click zoom zoom enhance enhance hey lets email this to the expert in LA) or 1000 negatives (lets make chemical soup x 1000 and bust out the magnifying glasses)? Even if the hypothesis about "less digital photos remain" holds true (which is preposterous), certainly the accessibility of the digital images more than makes up for it - if a diligent investigator / journalist can access the images from his or her desk or dump them on his or her laptop, then they're ten times more likely to peruse the images for shady stuff in the background. Argument inverted.
Issue #3 - Obviously off-site backup of perfect-copy images is an impossibility in the land of real film, but a nightly automated process in digital film land. Not to mention that optical media and redundant backups means a virtually infinite shelf life, versus the sub-century longevity of developed 35mm film. Argument inverted.
I'm surprised the silly "digital photography means you can't prove faked images" argument wasn't raised by our loom-burning film lover.
Issue #4 - In some ways, it's no different to the invention of the telegraph a 100 odd years ago, when it suddenly became possible to transmit messages over long distances in a very short space of time.
This is RUBBISH. A telegraph was ephemeral - a transmission and a disposable record of the message sent. Digital photography opens the doors to PERFECT, archival of INFINITE DURATION (with refreshing and conversion to current media, all of which is lossless). Could a worse example have been chosen? She could have compared it to the invention of the electic can opener and been less out to lunch.
Issue #5 - We don't have the build-up, we don't have the aftermath, we don't have incidental shots of who was there. Au contraire, mon ananas. If you're reloading every 24/36 shots, you're taking a lot less incidental shots than if your camera will hold 200+ images. Not to mention those cameras that permit the recording of simple video and/or audio in case all hell breaks loose. Would that not provide more build-up, more aftermath, and more incidental shots?
I could go on but I guess a lot of this is pretty obvious. Strange day on

The storage capacity issue is easy to address. A film photographer carries several rolls of film. A digital photographer can carry more or larger memory cards. There's no reason a digital photographer can't take and keep hundreds of pictures if necessary.
I suspect the problem really begins once the photographer gets back to the office. He may have been too busy to do editing in the field, but he might take the time once he gets back. If he doesn't, his editor might. Maybe they have a librarian that manages their archive. The point is, someone in the office will ultimately decide what is kept and what is deleted.
This is the big difference compared to film. In the world of film, it's customary to file the whole roll of negatives. It's a lot easier than picking through each roll and clipping individual frames, plus the film is easier to handle and store if it's kept in strips.
Storage cost with film isn't really a big issue either. Because of the way film is organized and stored, you don't save much storage space by clipping frames. It can even take more space than filing complete strips. By default, unless you decide that every frame on the roll is junk, you will probably keep everything.
In the digital world, the opposite is often true. Someone has to decide which images to archive. The rest are deleted. Of course you can archive all of the image files, but there's little practical reason to do so. Why bother when it's so easy to pick the ones you want?
And, unlike film, storage costs are an issue for digital images. There can be a direct increase in storage costs for keeping everything vs. selecting a few images. If your custom is to store each shoot on a separate CD, then keeping everything isn't an issue. If you're using online storage or consolidating multiple sessions on a single piece of media, then culling your work saves money.
I'm concerned that just giving digital photographers more/bigger memory cards won't help the problem. We really need a commitment to archive all of the images taken. Then we can worry about finding a digital medium that we can still use in 100 years.
Well, these days you can write a history thesis on just about anything....
As a professional historian, I actually think the greater potential impact of digital media on the historical record lies in it's vulnerability. Those who have undertaken the task of "rewriting history" to fit a particular agenda or world view in the past faced a profound obstacle: the existance of the physical record. Burning books, destroying documents, and manufacturing evidence took a lot of energy on the part of the Soviets & the Nazis [ and lots of others ]. Will electronic documentation have the same persistence that the physical record had? Or will the tyrant-de-jour simply order the re-creation of the historical record by virtue of a well-constructed worm? You'll recall the industry of historical revision in Brave New World. Hmmm... interesting, but I won't lose sleep over it.
"When I grow up, I'll be stable."
...is not just what might be lost to deletion. In terms of raw storage space, a 650MB CD-R has a bookshelf full of books, boxes, negatives, etc. beat hands-down. The real problems that I see with digital storage have nothing to do with the longevity of the data itself. There are several issues that have great bearing on the preservation of history when it comes to digital media, however.
One of the biggest issues is the *accessibility* of the data. Anyone who can see is capable of looking at a hundred year old photograph. Most fairly literate adults would be capable of reading (or at least puzzling out) a written document that dates back dozens or even hundreds of years. You have to go back many centuries before you require more than a good knowledge of the current language and a strong light source in order to read someone's old letters, and even then, all it takes is an education in the proper language of the period. No special tools required; just the proper knowledge.
With digital media, this is no longer the case. No human I know of is capable of reading a CD-R by eye. To access data stored in this fashion, you need a computer with the proper hardware and software. At this time, this presents no problem; few computers today come without CD-ROM drives, and you'd be hard-pressed to find someone with absolutely no access to one. But that may not be the case tomorrow. Ten years from now, CDs may be obsolete (sooner, if the RIAA has it's way...), and then it will be hard to find a machine that can read one, except in the workshop of some computer hobbyists. In twenty years, the number of people with access to an obsolete medium will be very small. In fifty years, it would be virtually impossible to find someone with equipment that can access the data. In a hundred years, few, if any, ordinary people will even know what the hell a CD is, much less know what to do with it. Think about it...how many of you out there could access data on an 8" disk? How many of you know someone who might be able to? I'd guess the numbers are relatively few, and this is a technology that, relatively speaking, is not all that old. And that was a common format. What about people who are storing data on less common media, like LS-120 disks or JAZ drives? Anyone around here have a drive that can read a flopticle? An optical disc? I was using those myself to store data just six or seven years ago in high school, but I'd be hard pressed now to find the hardware and software to read them.
Another problem that occurs, and is related to what Ms. West wrote, is the transitory nature of everyday electronic communication. Personal communications like letters are perhaps one of the best windows into the everyday life of people who lived long ago. Today, though, email and voicemail have replaced letters as the predominant form of communication. While this is great in terms of speed and efficiency, it also lacks the longevity of a handwritten letter. Many people saved old letters for years, and kept them in the family. Most people I know don't even save their emails for a week before they're consigned to the void. I'm an obsessive-compulsive pack rat who doesn't throw anything away, so I have email that dates back six years and three computer systems, but I am far from normal in that regard...and in ten or fifteen years, chances are very good that I'll lose all of that mail somewhere along the way. And when email is lost, it isn't buried in a long-forgotten box in a dusty attic somewhere, waiting for someone to stumble on it one day in the future. When email is "lost," it's gone for good. The chances of any personal email communication (barring spam, famous chain letters, etc.) lasting more than ten years are slim to none. Use of "snail mail" for personal communication has declined sharply in recent years, as people move to email and other forms of electronic communication. Stuff like the current anthrax scares will only make more and more people turn to electronic communication as a safer, cheaper, faster alternative. But as they do, the trail of personal information they leave for future generations becomes smaller and smaller. A hundred years from now, our descendants will know far less about us than we know about those who celebrated the dawn of the 1900s. The effective lifetime of the records we leave behind has shrunk significantly, from centuries to decades, or even mere years. It's kind of scary when you realize that in fifty years, such an enourmous chunk of what defines this time period will likely be gone without a trace. The more we move to electronic communication as a way of life, the larger that chunk will be. One day, we may have no history except that which is passed down directly from generation to generation...much like the days before written language was invented. Strange thought, isn't it?

Slashdot editors should re-read the story instead of making out of hand comments.
West is _not_ criticizing the images that actually get published. She is criticizing all that get deleted. You don't go ahead and save every image you take to your harddrive, as you then have to buy a new harddrive all the time. Its much more convenient to just delete what you think is irrelevant at the moment.
With a film that is not possible. The film stores it, at least "semi-permanent", that is, at least a couple of years or 20.
Of course, you get a buttload of film to handle, and someone needs to review all that film, but thats beside the point.
The point is that she worries that history get lost, due to all the deletion of material. She would NOT be worried, if every journalist/photographer just saved _everything_ to harddrives, and never deleted any pictures. _Then_ she, according to her article, would be perfectly happy with it (she doesn't say so, but its obvious out of her article).

The point is that very few people do burn their negatives.
In my closet, I have stereo slides taken in the '50s by my dad from before he met my mother. I also have most of the negatives from my childhood, and thousands of negatives that I've shot since then. Negatives are relatively compact, and easy to store for a couple of decades (longer than that and you should be explicitly nice to them).
What we're dealing with in this digital vs film case is the default path for the 'uninteresting' pictures. With film, the photographer would drop of a bag of film rolls at the processing lab, and the editor would get a stack of negatives, chose one (or a few) and be done with it.
In this case, you now have, besides the one or two printed pictures, another dozen or hundred that didn't make the grade, today. For the most part, these pictures cannot be reused, but it is pretty easy to put the spare pictures in a book and stick it on a shelf for a few years.
With digital, a couple of 'bad' pictures (like the picturs of clinton with 'that intern chick') might get culled before it even made it to the editorial desk. The images that aren't used, on the other hand, are on a $200 hard disk that is very reusable. One click of the mouse, and you once again have space for another 300 images.
Most consumers don't realize the quantity of film that a news photographer can go through. You don't count frames. You count rolls. If a news photographer tells you that he's got 3 rolls left, he's not bragging. He's probably worrying.
BTW: At 3Meg each, someone mentioned that his camera has room for 330 images (~ 9 rolls). This is about the number of pictures that I'll take at a friend's wedding. I'm not a news photographer, but I go through film like one. (must come from volunteering for community newspapers). A 20 GB drive wouldn't store a busy year's worth of my pictures at decent resolution. Then I would have to decide if I'm gonna try and fit another 20GB drive in my box or cull most of the pictures.

Sometimes boldness is in fashion. Sometimes only the brave will be bold.
I worked for the Columbus Dispatch in Columbus, Ohio as an intern in the photography department.
This article, while brining up a few interesting points about digital and how it may or could change things, what I actually saw and was a part of painted a different picture, but this may be only unique to this one newspaper.
The photographers were all armed with Canon EOS digitals, I had my own Olympus E-10 and some had the new Nikon D1X, which is quite possibly the greatest digital camera to ever exist.
Anyway, most had 256 MB CF cards or in the case of the Canon digitals, several GB PCMCIA drives which could hold thousands of full quality, often times RAW (uncompressed) pictures. Those with CF cards could hold about 40 raw pictures per CF, or around 200 1/2.8 JPEGs (still very high quality). The best part of all is we could share the cards, so if one didn't need 50 MB on their card and someone else did, we could use their card. Try doing that with a half exposed roll of film.
Most of us shot in high quality JPEG, because you couldn't tell the difference between that and raw if you didn't magnify the image 5x. This saved space, which is still valuable, and affored us the quality we needed for front page spreads.
When we would finish a shoot, we would save all the digital images on CD. The film guys, on the other hand, would throw away the negatives that didn't make the cut. There was simply no place to put them and the care and cost of chemicals required to maintain them was too expensive. However, all our images were backed up on CDs and filed in a safe. Pure, digital copies of our work. In other cases we would have a laptop on site and would simply slide our CF in with a PCMCIA adapter and in 5 minutes have 200 more shots ready.
I think the situation this woman speaks of is that like the early days of digital, when you were limited to $250 32 MB cards. However, today a 320 MB CompactFlash card can be had for under $100, and a 1 GB micro-drive is around $400. I rarely think a photographer brings enough film for 3500+ pictures on one shoot, which one could fit on a microdrive with a small laptop (over 100 roles of film). Plus, the 2 GB and 5 GB microdrive versions are just on the horizon, offering even more on field capacity.
In fact, if anything, the cheapness of digital makes photographers take more pictures. Lets not forget the time factor. There is NO developing, no scanning, etc. You can take a laptop and even transfer the images back by modem if needed, or plug into the nearest network. And today, when all layout is done on computers, this just makes sense.
I think this woman tried digital when it was in its infancy and backed away from it and now has a film only attitude. Well, she should really try the Nikon D1X SLR and a 1 GB microdrive. I think she'll be leaving film for good when she gets some of the images from that camera (which technically has greater resolution and dynamic range than a 35 MM negative).
Even my Olympus E-10, a prosumer model, rivals film to the point where the images from the camera are sharper than any scans I can get from a 35 MM negative.
Also, there was something mentioned about the durability of film vs. digital. Well, may I remind you that film cannot be kept in hot temperatures. This is why people refrigerate their film (before and after exposure). Digital has no problems in hot weather, albeit the CCD does produce more noise when the temperature rises, it doesn't completly fade away the picture like film would. In the cold, dew forms on film negatives and moisture damage is a huge problem. With digital this isn't a problem at all, and most CCDs perform better in the cold.
The best part about digital is that its a growing field. It follows Moore's law, and in five years we could be looking at over 20 mega-pixels of resolution at all types of ISOs (film has only one ISO while the D1X can go from 100-800 by pressing a button), greater than medium format and rivaling large format. This is greater resolution than 35 MM will ever be able to provide.
All through that women's article I find it odd no one has mentioned she is attacking digital archival. She seems to think digital will reduce the nation's photographic libraries, when other mediums, such as print, etc. have been the poster child for digital archival and everyone is so glad the old days of microfilm and paper are over. In fact, digital archival for photographs is easily suited for the task. It's much easier to query a database for "September 11th 2nd Plane" than look through an entire seleve of negatives, or go through a convoluted filing system. When I worked, all digital images would have to have a title, a description, where it was taken, and the identity of anyone pictured (if not a crowd shot). This is what we would do after we get back. The embedded EXIF data in the image, as recorded by the camera, took care of the date, ISO, shutter speed, and other technical information (again, not present with film). This would then go onto an online storage and retreival system, and backed up on CD.
Now as for being an on-site editor, as someone mentioned, and having different goals, this just simply isn't true. An editor and a photographer both have the same goal: getting a good picture. When the photographer arrives back, often times there simply are no *really* good pictures to choose from (you know the feeling of "This one's good enough, go with it."). However, with digital's instant preview of a captured image, a photographer can instantly gauge his efforts and dynamically adjust his shooting style based upon his output. He can progressivly work to attain a greater image by building upon the one he just took, which is impossible with film. This is what we did at an event, and since we were editing on site, we had the benefit to go and take more pictures. Back in the film room with a magnifying glass you are only limited to the selection of what was took -- in many cases that one picture you "had in mind" was lost forever. However at the scene we have the benefit of doing a reshoot without even having to step foot in a darkroom.
My only current complaint with digital is the time factor. Film is still faster at taking images, while digital sometimes makes you wait while saving and compressing images. This is a temporary problem which will soon be corrected as embedded processors get faster and portable storage write speeds increase. Still, this is one area where film wins. Still though, the two and three second waits of today's professional models are getting very close to what film is capable of and burst mode on many cameras gives good results, especially when you're in the middle of a press mob and you only have a few seconds to snap that picture of your subject -- every frame per second counts.
Now, it seems, film is nearing death and the last survivors are clinging onto it like one would with a sick family member. Digital is here to stay, is growing, and no matter what arguments that woman seems to claim, it's the new way for all types of photography. I sent her an e-mail with a link to the D1X and a copy of this post. I think she's just about to change her mind...
