Ready for that ? To post a comment from another thread (Buy film, not equipment -- is that considered crossposting?), which is the same garbage Kodak has been practicing with some of their films and _why_ they've eliminated outstanding films like Pan-X. |

In article , Helge Buddenborg wrote: That's my opinion and I'm sticking with it, "Digital Photography is "GREAT". What he misses (completely) is that digital imaging, though an imaging medium, is not a *photographic* medium. The physics simply don't support this. And when people begin to see through the marketing hype and in 20 years lose all those non-existent image files on their hard drives they will realize film is the better medium. There simply is no permanent archival storage for digital and never will be, since as mere data it's dependent on 100% on electronics rather than concrete materials. There is no permanent archival storage for data, yet. Read my lips: it's electronic. It can _never_ be permanent. It's ones and zeros, mere data, representational, not a real image, 1000% dependent on electronics and the storage mediums that can actually read it, which changes constantly. Shall I go on? However photographs are not the only data that need this kind of storage, so active work is being done in this area all the time. Guess I need to go on: There's no such thing as a digital "photograph." A photograph is a real, tangible image actually created by the action of light on a light sensitized material. It's chemical and permanent. Even if the emulsion degrades due to exceptionally horrendous care and storage, the silver metal compounds it's composed of lasts forever. Digital disappears the moment your hard drive, CD-R, DVD, etc., fails. Not to mention silicon doesn't record anything (it can't, the physics don't allow it) and the regenerated voltage/image data stored on your computer is, all together now -- mere data that represents an image. That's what the science says. There are methods that work, for example take a solid gold disc, now burn pits into it with a laser beam, similar to a CD master. Since gold does not corrode, or tarnish, the data would exist until the Sun goes into melt-down. What is really needed, is a very long term storage, something on the order of 500 years or so. This would be longer then most photographs need to be retained, This makes zero sense; reminds me of king dubya talking about foreign policy... and longer then film will last, Ignorance abounds. Film (according to Dr. James Reilly of the Image Permanence Institute) begs to differ. If properly stored, his Storage Guide for Acetate Film states film can theoretically be preserved for thousands of years. Regarding film on polyester base (b&w sheet films like Tmax), these are stated matter of factly to have an estimated life of 500 years even when stored under normal "room" conditions. If the images on film or paper are toned or otherwise protected from oxidation, the emulsions should also last. would need to last under less then ideal conditions. The problem is that you would need to wait 500 years to see if it lasts 500 years. W W/dubya? hmmm...must be related. Manufacturers market digital as "photography" instead of data imaging because that's the only way they can sell it. Digital cameras aren't "cameras," they're scanners. Consumers buy into it for the convenience, but experienced photographers are better educated. As the ISO has noted digital doesn't produce a photograph, it produces representational image data. Film, OTOH, is a permanent tangible image, not "data." And that's why film will always be around. |

(At least here on Earth.) I wonder... what will be the situation in another 475 years? Nice of them to include the replacement cartridge and needle, though. A Radio Shack might be hard to come by... But, just as an interested amateur, much less a professional scientist or engineer, could easily create an optical system to view or project a photograph even if the very idea of photography has been lost to time, It's called a pinhole and has been a scientific phenomenon known since about 300 BC when Aristotle first described it. About 400 years ago some smart people added optical glass (lenses) and before we knew Kodak did it in reverse and created the slide projector. BTW, the "very idea of photography" is just as basic a phenomenon of science as the pinhole. Digital, OTOH, is a phenomenon of technology. anyone capable of retrieving the Voyager disks and reading the symbolic playing instructions would be capable of fabricating a stylus and cartridge. The inclusion of those devices just makes it easier; they need provide only amplification to listen to the audio portions of the record. I could probably manage that myself, with my extremely limited electronic knowledge; it should be trivial for anyone capable of retrieving those disks from deep space (assuming they see, hear, and think even a little like us). Viewing the images would require some computer capability or a lot better knowledge of analog electronics than I possess, but again shouldn't be a problem for those capable of finding the disks. The only way I see those disks as being information to retrieve is if they're found by too mature a civilization -- if they've reached the stage where "trailer trash" routinely lives and travels in space, Now hold on there. I know people who live in trailers and they're quite nice people it's very possible that the finder might be technologically (or genuinely) illiterate and see the item as simply metal to be recycled as scrap, a wall hanging, etc., without ever realizing it contained information -- or be ignorant enough of scientific constants to be unable to decode the instructions for rotational speed etc. even if they understand the disks contain information. Imagine a Dust Bowl era Okie confronted by a message encoded in terms of the dimensions and tolerances of parts inside the engine of his clunker Ford; he might well be able to repair most common failures, but likely wouldn't know what a micrometer is for, much less how to use one, and still less likely own one -- and even if he does, his worn old engine might be far enough out of tolerance to render the message indecipherable. -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E.

The thing is that people find working in the dark uncomfortable. I believe there are a significant nubmer of people (including myself) who make the digital/traditional decision based on their experience of the process. I sit in front of a computer all day (and am paying the price for it with my neck pain) and would therefore prefer to use the darkroom. But for this discussion I want to leave aside those sorts of questions about personal preference for the process. I'm interested in the fundamental question of which technology produces better photographs and why. Your answer to my question is a good start. But I still need more information. Also they believe the spinmeisters when they tell them it's going to be easy for them to capture and print "photoz" on their inkjet printer. As if an inkjet can render a decent black ! I have some comparison prints I keep on the walls of my cubicle. A contact print from a 5X7 negative (Tri-X), several RA-4 prints made from a Fuji Frontier from my 6MP FinePix along with a coupld inkjet prints my wife made. Inkjet prints look like water colors, the Frontier prints aren't much better and of course the contact print is perfect. Ok, now suppose you can afford to have your digital images printed by one of those proceses that exposes digital images on traditional paper using lasers. I'm told the quality of such prints is phenomenal (and the price astronomical). Assuming that the quality of such a print equals or surpasses that of what you could produce in your darkroom (assume hypothetically if you disagree with the assertion), is film capture of a black and white image better than digital? If so, why? Does film have a better dynamic range? Is it easier to manipulate the contrast? Etc., etc., etc.? Again, please restrict the universe of discourse to black and white. I don't care about color. Thanks. --Phil |

A regular old darkroom need not smell, let alone have 'fumes'. Probably people who use digital printers operate them correctly.

Fact is, nobody knows how long it takes nature to break down the molecules in polyester or acetate. It may be 100 years it may be 100,000,000 the key is that it does start to break down at some point, and that point is so far an unknown. They thought plastic buttons from the 1900's would last forever too, until museums had to replace them because the buttons were deteriorating, and affecting the garments they were attached to. If the buttons were "plastic" from the 1900s, they're celluloid, the same unstable stuff that ate so many of the early Hollywood films as it decomposed in storage. Completely different from acetate and polyester. Yes, I agree, no one is certain of the breakdown time of polyester and acetate film bases (other than that polyester is likely longer); these materials are both so durable that other than a few bad batches and in cases of long-term solar UV exposure, they haven't broken down significantly in the 30-40 years they've been available. However, based on the earliest examples known, they look to be competitive with paper for longevity (and likely better in some environments, since they aren't food for bacteria or fungi as cellulose is). We have many-many examples of paper up to 5000 years old. Suppose they invented a new memory next week, that allowed you to store 500 exabytes (87 262 827 images from a Canon digital rebel in Raw format) would last as long as the planet does, and never become corrupted, even when at ground zero under a Hydrogen bomb. You probably still not be satisfied. I doubt anyone could prove the ground zero claim or the longevity (they said something similar about CDs when they came out, remember? "Won't skip like a record, and will last centuries!" and then they found out the aluminum coating oxidizes between the plastic layers and the things can become unreadable in a matter of 10-20 years in normal storage; I heard one skipping on radio within a few months of the stations starting to play them). The capacity would be wonderful, but it's still not human readable. And all the rest of your arguments apply equally to digital media as to negatives -- sure, people may toss them rather than spend the effort to decode them. But a medium that stores an eyeball-visible picture, IMO, has a better chance of catching someone's attention long enough to be preserved than yet another box of those stupid old CD-R disks that have all deteriorated in the 50 years since they quit making them. And though no one might have a darkroom or "conventional" photographic materials in 100 years or 300 years, they'll still have some means of imaging the negatives and converting the image to a positive (that's an extremely simple computer operation); a silver gelatin negative can even be directly viewed as a positive, after a fashion, by putting it against an absorptive black background and viewing the scatter from the silver -- a trick that gets rediscovered, by accident, pretty frequently. No, of course not every preserved negative will be saved when it's found in the attic -- but neither will digital media. People pitch stuff when they buy or sell a house, move apartments, or just cleaning up; many of them, using the "one year rule", would simply erase all of history if they ran things, because they haven't used it in a year so it must be junk. My point is, an analog image will still be eyeball visible long after digital media are irretrievable, unless digital progress stops cold tomorrow (or next week, at the latest) -- which isn't going to happen. And an eyeball visible image is more likely to be preserved when found than a bunch of disks or memory cards that don't fit any hardware you have on hand or have ever seen. Would you bother to try to read an 8" floppy if you found a box of them in the attic? Even if they were labeled something like "CPM-86 Version 1.0"? Even if you knew that was the system that Gates and Allen bought up and relabeled to create PC-DOS 1.0 when IBM wanted an operating system and Digital Research couldn't or wouldn't commit to deliver on time? OTOH, would you stop to look at an old B&W print of a couple of geeky looking young adults with an old computer case (complete with front panel switches and status lights, like in a Star Trek rerun), long enough to turn it over and read "Bill Gates, Paul Allen, 1976" on the back? IMO, and we might just have to agree to disagree, the box of old pictures is much better off, in the hands of someone cleaning the attic, than the box of old computer media. And if the pictures are B&W on silver gelatin, either prints or negatives, they're likely to still be in reasonably good shape even 200 or 300 years down the line (at least as long as they weren't on celluloid base). -- I may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E.
