Film theorist Laura Mulvey coined the term "male gaze" to describe the "masculine, heterosexual perspective that presents and represents women as sexual objects for the pleasure of the male viewer": in a paper for the Harvard Journal of Law and Gender, Southwestern Law School professor John Tehranian applies Mulvey's idea to the complex and often nonsensical way that copyright determines who is an "author" of a work and thus entitled to control it, and shows how the notion of authorship reflects and amplifies the power imbalances already present in the world.
Copyright law presumes the existence of an "author" in whom copyright can be vested, but the concept of an author is complicated, especially as media have become more bound up in the cooperation of multiple parties (photographers and subjects, actors and directors, etc).
The actual rules of copyright tend to follow industry practices: that is, the industry arrives at a certain way of doing things, and then there's a dispute, and the courts usually look at how the industry is doing things, and declares that to be the law (or sometimes Congress enshrines into law the existing practices of industry). In industry, there are always power imbalances that reflect underlying social conditions: the person who owns a movie studio has more power than the actors they hire, the record label usually has more power than the musicians it records.
So as courts were asked to develop a theory of authorship, they arrived at the idea that the "author" is the person who commits the work to some tangible medium: the photographer, not the model; and where there are complex processes involved in that tangible fixation, the "master mind" orchestrating the production becomes the author (the director, not the camera operator).
