Since I use only a laser printer I haven't researched black or colored
inks.

Black and white photos, selenium toned and archivally processed will
last 100 years and probably far longer. Isn't it amazing how well some
photos from the past have survived, even though made without the
archival knowledge we have today? I have some photos, still in excellent
condition, that were made more than 140 years ago in a little town in
Illinois.

As noted earlier, laser prints are estimated to last 200 to 400 years,
dictated by the paper on which they are printed.

Depending on CDs for long-term storage of pictures is highly
questionable! No one yet knows how long a CD (either burned or
rewritable) will last. It's a question the music business wishes it had
an answer to.

In my opinion, topics like this that affect almost all list members are
"on topic" as long as we don't overdo it.

Sorry I missspelled Daguerreotype in my original post.

Cheers, Jim
