Okay, explain.

James Grimmelmann, a law professor at Cornell, breaks this down really well.

Under standard copyright law, you are protecting specific individual images.

You cannot copyright a general artistic style.

University of Maryland technology and law professor James Grimmelmann told Slate, "If you are exposing people to something that causes changes in psychological status, that's experimentation.

This is the kind of thing that would require informed consent." And take The Atlantic's headline, "Even the Editor of Facebook's Mood Study Thought It Was Creepy." Facebook told The Atlantic it's only doing this research to improve its services.
