There has been some ongoing discussion about noise in digital pics and the
general assumption is that it is a "bad thing". Camera manufacturers work
hard to eliminate it, as discussed in the recent posts over the FZ30.
However, I came across a blog today which cites an academic paper suggesting
that noise can also be your friend. I have pasted the blog below, followed
by a link to the paper.

The comment about the possibility that Canon "build in about the right
amount of noise" is something that Panasonic might take on board.

But noise can also be ugly, jagged, nasty blotchy and totally unlike
film grain.
