Forgot to add that in a lot of cases (especially fashion shoots), there is more equipment needed (lighting, reflectors etc) and normally a second person is needed to 'handle' this equipment during the shoot. We are working with our photographers to give every one of them access to this service/equipment and normally one of the models will help out as the second person, keeping costs low.
