Amusingly, I have in my hands the book Photoportraits by Henri Cartier-Bresson, who knew one or two things about photography.
In this book of 255 portraits it is accurate to say that exactly zero of them have the subject filling the frame. This fetish for tight crops I see on TPF is pretty amusing, but only sometimes right.
If this were mine, I'd be looking the other way, though. Having the sight line lead immediately out of frame is a little out of balance.
