That's not entirely correct. The "DP" doesn't choose camera angles. That's the director's job. But once the choices are made, the DP, working with the gaffer, etc. make the shots work in practical form. Making sure the lighting is correct, the proper lenses and film stocks are selected to get the needed composition, figuring out how to shoot in a given location, that unlike a studio set, has no walls that can be moved around and so forth.
Of course, people are different and have different ways of working. I've certainly worked with directors who because of their uncertainty or laziness will leave it up to a skilled DP to choose camera angles, and many a DP has gone on to be a director themselves.
