Copyright versus creativity

Briefly describe your understanding of copyright, fair use, and creative
commons. How do these terms relate to one another?
2) You have a blog that has become very popular with friends and
strangers. They tell you that you are a great storyteller and a fantastic
photographer and should write a book of your adventures.  You decide
to self-publish a book of the stories and pictures you documented on
your last trip and hope to make a little money from this venture. The
book will be available in electronic form, so your pictures will be easy
to “borrow” online. Would you apply for a copyright, a Creative
Commons copyright, or no copyright at all? What is your reasoning?
