A Great Lecture About Photography and The Copyright Law
There are a lot of misconceptions about photography and copyright. Some of the more common questions (and wrong answers - at least on the net) concern copyright ownership, photo usage, online usage, fair use and licensing.
Others concern model releases, invoicing & payments (and their relations to copyrights) and legal documents and wordings.
Jack Reznicki and Ed Greenberg A.K.A The Copyright Zone (and authors the Photographer's Survival Manual: A Legal Guide for Artists in the Digital Age) have a great lecture on B&H indepth blog.
It is a one hour and fifty minutes long lecture, but it clears a lot of the questions and misconceptions around the subject of copyrights and well worth the time watching it.
