I'm curious about the legal position on tracing as a derived work (probably different in different countries). Perhaps Microsoft saying it does not consider tracing to be a derived work does not stem from their largess but their reading of the legal position. Amongst artist friends I've heard discussions about copies being considered autonomous artworks as long as they are not exact duplicates. I believe it stems from the legal protection offered to art works which parody or comment on other art works, collages, as well as art students creating their own copies of art works in the process of studying. Some artists have even created meticulous copies of famous paintings but at different scales and in different contexts as a way of comment. Did Andy Warhol breach copyright when he turned photos into screen print images? A hand traced copy of a feature produced from a photograph may well be sufficiently distinct to not be considered a derived work. Any copyright lawyers in the house?
