The photographer generally has rights to their own work except under "work for hire" arrangements (which doesn't just mean "got paid"). (That varies by jurisdiction, of course; until recently, copyright law in Canada held that the commisioner of a work of photography or a portrait held copyright. That section of the Copyright Act was repealed, and the law is now more-or-less consistent with US law.) What the photographer does not automatically hold is the rights to use a person's image for commercial purposes (advertising and the like). That requires a model release, and a model release, like any contract, requires consideration. Like, say, a discount or prints/files.
