What is Copyright?

Be it a painting, a photograph, a poem or a novel, if you created it, you own it and it’s the copyright law itself that assures that ownership."

Copyright expires 70 years after its first publication or 70 years after the death of a creator.
If you are the creator you automatically are covered by copyright law and others need to acknowledge your ownership.
