^ i think that grossly underestimates the knowledge of photographers. the gap between the technical requirements/knowledge needed by photographers and models could not be greater. i am not saying modelling is 'easy', but if you can say that about photographers than you could easily say all a model needs is to be photogenic (and thats often something you are born with).
of course some shoots are easier for a photographer (ie look books in front of a white back drop), but to shoot outdoors (and indoors with numerous props, different artificial lighting, multiple girls/guys, different focal points etc) is not that simple
