Chuck will need to understand copyright law in order to ensure that he never uses an image without the proper rights. Copyright law protects the rights of creators of original works, including photographs, and gives them exclusive rights to reproduce, distribute, and display their work. Chuck will need to understand the basics of copyright law, including what constitutes infringement, how to obtain permission to use someone else's work, and how to protect his own work from being used without his permission. He may also need to familiarize himself with fair use exceptions and other limitations on copyright protection.
