More Words, Deeper Hole

Generally, photos are picked by the editor or sub-editor; the writer won't have a lot to do with the taking of the photos, even if the interviewer and photographer are there at the same time. The journo has responsibility for the words, and the camera-guy for taking a lot of pictures. It may even be the case that the interviewer does the interview by phone or Skype these days, and the photographer is someone local hired for the shoot, I don't know.

If it's an important piece, then the art director might have some input into the picture selection. If it's a minor piece then their only input would be selecting the cropping. Similarly, the writer won't be writing the captions; that's a sub-editor's job, like the title of the piece.

Some papers do things differently, of course, but generally only the most visionary and penny-pinching papers will have one person doing three or more jobs. Generally, people who are good at writing aren't too hot with a camera, can't edit themselves, and have not a clue about page layout.
