Excellent article that highlights a real problem. People don't realize how inferior the permanance of injet prints is in comparison to that of real photographic prints.
I have a few inkjet-printed images that have been sitting, framed, at home on shelves or bookcases, in sunlight, for about 4 or 5 years. They're almost completely devoid of color by now.
There are regular color prints sitting next to them, from the mid-1980s on up, and only the oldest ones show any signs of fading. It's still nothing near that of the inkjet prints.
Compare this to one of my grandparents' wedding pictures from 1932, which has hung directly across from a window for 30+ years. It has not faded in the slightest, and looks exactly as [I'd think] it would have looked over 70 years ago. Do THAT with an inkjet.
Whenever I discuss this with people, they say, "yes, the prints may fade, but my image FILES will survive forever".
Ok, in theory, sure. BUT, will the media they are on survive? Will someone accidentally delete them? Will you be able to read the filesystem on the media? Will you be able to read the image format? In a time 100 or 200 years from now, I'd venture to guess that the answer will be "no" on all counts. How many people do you know who can read disks or tapes made on a Commodore 64? I bet its very few (if any). And that was only 25 years ago. Give somebody a CD-ROM or an SD card 100 years from now, and you'd be lucky if they knew what it was, much less be able to read it!
However, you will ALWAYS be able to build an arrangement of lenses, mirrors and lights to display or print negatives or slides.
That was long winded. But it's my two cents!
