When we start making photos we really like, we often want to share our work with friends and family. Many of this have been doing this through social networks. For the most part, users never read the terms of service put in plain sight by these services. My own experience is that the terms are very clear about what you surrender, what rights you retain and how your work can be used. If you’re going to play in social media, the responsibility for knowing the waters you’ve jumped into is yours and no one else’s.
