You don't have a cite. All you have is the fact that
they lost the images. They can't find them, but it
isn't that they are in a format which cannot be read

have them any more. It makes no difference if you toss
film into the trash or a tape of digital images into the
trash, the result is the same.

You didn't read far enough. The reason for the search was simple. The last
tape drive capable of reading them was scheduled for destruction. It now has
been destroyed. Even if the tapes turn up in perfect condition today, the
information is gone forever.

If the tapes were found, and they actually are worth
something... rest assured that a new tape drive to read
them *can* be manufactured. The format specifications
are not exactly unknown (except perhaps to you).

Your argument is not just baloney, it's *stupid*.

And so is the above, and the one that followed.
You aren't getting any better...

....
Your original statement was they would be unchanged so I take your words perfect
condition to mean that. That is false. Do you think a .jpg will be readable in
500 years? Heck no.

I see no reason at all that a JPEG file would not be
easily readable 500 years from now.

The information needed to read it will still be
available. It isn't a secret it's an international
standard, and it won't be lost in a NASA archive.

If there is a chance in hell of a single file being
readable then several times in the 500 year time span an unknown human will have
had to compress the file into some new format as they change forever altering
the image, losing information and altering color if not exposure and contrast.

You don't understand digital data, nor JPEG image
formats! Claude E. Shannon demonstrated,
mathematically, the significance of all this back in the
late 1940's. He of course worked for Bell Labs, and the
first industry that was stood on its head changing to
accommodate what Shannon said was the telecommunications
industry. They basically went digital 40 years ago.
And since then virtually every other industry, as the
technology necessary is developed, is doing the same
thing. It only started in the photographic industry
10-15 years ago, but it is now approaching critical
mass, where virtually everything will be moved to fully
digital. Learning about why that is would help you advance
into the future...

Over the next 500 years people will be able to retain
the exact data as it exist today. They will also be
able to convert it to other image formats, just as
easily as we can today. That is of course in addition
to saving the original data to multiple different types
of media.

The same is true for various camera RAW formats, for
PNG, PPM and TIF image formats, not to mention a dozen
or two others.

But in 500 years any roll of film exposed today is
necessarily going to be crumbled to dust. Any copies
made from it are necessarily going to be progressively
degraded.

Nobody
is saying that every digital image will be preserved,
just that some will be. There will not be *any* film
images preserved unless they are transfered to digital
data files.

Really? No film?!! Not even one frame?

For 500 years??? You're delusional.

Speaking of that, what happens at 03:14:07 UTC on Tuesday, January 19, 2038?

You get another lobotomy?

You really should look that one up. It does affect you.

It doesn't. You should look it up. And get some kid
who's a computer whiz to explain it to you, and ask her
to repeat it until you understand.
