I found out that clients and photographers look differently at the same photos. Photographer estimates complex of factors that make a presentable picture: light, composition, poses, emotions, colours etc. We don’t look just at the face of a model.
However, the the most important factor for client is her or his beauty. It’s absolutely normal because this is that very purpose of people to take part in photo shootings. You should be satisfied by process and result.
Moreover, each person has his or her own criteria of loveliness. Sometimes photographer, audience and model have different view on the model’s attractiveness.
So, that is why if I make creative photo session for my portfolio I select photos of my own choice according to different measurements.
If I do commercial photo shooting the photos selection is only of the client’s choice except such cases when client asks me to choose photos by myself.
