filmscanners: image samples of digital artifacts

[Dan Honemann]

Is there an online tutorial/FAQ/glossary somewhere that shows image samples
of various digital artifacts (e.g., banding, grain-aliasing, jaggies, etc.)?

I'm a newbie to all this, and Tony's glossary at halftone is a help but
doesn't show pics.  Here, I think, sample images would be worth a thousand
words.
