1. Many young artists copy from the masters. It was pretty true many years
ago. It is still being done in the Louvre because I saw it last February.
Learning from the masters is good but you need to move on to your own thing.
2. I believe that teachers are allowed to use copyrighted items in the
classroom, I might be wrong. If you are not going to profit from it I think
it's OK. I use examples from slides that I purchased from Universal slide
company which has already paid a royalty for them. I don't have a web site
yet and when I do I will be only using student work and I have them sign a
release form to do it.
3. I have not been concerned with the use of print sources. I might make a
hand out using some prints but they come out so poorly that I doubt that
anyone would mind. We don't have a fair use policy that I know of and I
believe that we have site licenses for all other technology.
4. I respect the work of others and the right to have compensation for that
work. If I was going to use prints or the work of another in a book or
article I would get permission first. With students this is easy when they
are in the classroom but it is hard to do once they leave. I have used a
release form from a publisher to get permission for future use in a book or
for the Internet.
