Your telling me it's illegal to pay someone to illustrate my copy of a book? It's illegal to commission a translation of a book for personal use? Is it illegal to pay someone to read a book to me?
you cant make audio books, illustrations, or translations of a book without the authors permission
note that text to speech isnt considered derivative work. its considered a tool rather than creating content. so its legal for a kindle to read it to you
I think you're confused, or at least talking past GP. It's not copyright infringement to create a derivative work - e.g. by adding illustrations to a book. What's infringement is if you copy and distribute the derivative work without a license to the original. GP was asking about the former, not the latter.
There's a case where a Japanese venue commissioned an art piece, wrapped it, artists sued the venue, and the court ordered the art be restored to the original state on the ground of copyright. I think it was a couple feet tall cat statue or something.
It's somewhat of a case by case basis matter and it's rarely brought to the court, but just because you own a piece doesn't always make it all to your discretion to modify it.
Yes, but that doesn't mean it's "illegal" to create a derivative work. It just means that the original author has rights they can exert over what you make.
I dont know everything i read online says its copyright infringement to create derivative works, outside of stuff like parodies, fair use and getting permission.
