When I took Doug Rea's course on photography on the macintosh a couple of years ago, (which by the way, i recommend to anyone, it's great). I learned about visually lossless images: human eye is the final interpreter. When I came back to work, I got into a discussion with one of my colleagues and found that lossy and lossless had different meanings for him.Since then, when I teach about compression, i give the generic lossless, lossy definitions then introduce the concept of "visually lossless" it seems to make sense to people.
