Hi Adam,
Maybe I don't know what to look for regarding digital noise as I can't say
I've seen anything creating a visual distraction in any prints I've made.
Even the 1600 Digilux 2 prints in B&W or colour

And if it doesn't look like grain of some kind, I'm beginning to wonder what
the heck I'm supposed to see.  Maybe there's something I can deliberately
try to create noise so bad I wont be able to miss what you lads are
describing. After all I'm still a super rookie with this digital stuff, but
finding it quite an amazing way of capturing images of excellent quality.

Now what can one do to create noise? A simple exposure of some kind or what
is it that everyone else does to actually see noise? Or create it?
