Well, I dont know if we are getting our definitions of required messed up or not, but lets see if we can clear it up.
It is required to have a photo release of someone in the photo if you are going to use them for commercial purposes, employee or not.
Its as much required, by law, as if you were to use one of my photos without asking me for commericial use.
When I said its not required, I meant it in a way that yes, you can do the shoot and not get one, but if you're ever brought before a court on it, you will lose.
Just as its not required for me to get a release one of your photos for commercial uses, but if I'm caught, I'm screwed.
The law is pretty clear, you cant profit off of anothers image without their consent. Now if in signing the papers to become an employee they are signing something giving up that right, thats one thing. But just cause I work for someone doesnt mean I give up the rights to my image being my image.
But it doesnt do either of us any good to argue over it. However, anyone that reads our posts should consider how its much better to be safe than sorry and having someone sign a release is one of the easiest things you might do on a shoot.
