The Photographer's Guide to Copyright, a robust downloadable PDF packed full of information about copyright issues was released this week from Photoshelter & ASMP. The guide gives a better understanding on how to protect still and motion images and how to safeguard your work from infringement.
In the guide you will find info on how to protect yourself, what defines fair use, registering copyrights and what to do if you have been infringed. This guide also provides in-depth interviews that will help photographers navigate U.S. copyright law, register their images and protect work from infringement.
thanks @fstoppers for sharing the free ASMP & Photoshelter Release Copyright Guide
I hope they come out with a similar document for other countries, like Canada :D
