The photographer you hire, despite how professional they might be, will not protect your brand. It is not their job to.
The makeup artist you hire, also, will not protect your brand.
The graphic designer you hire, surprise, surprise, will not protect your brand.
The singular person who can protect your brand is yourself. Thus when you hire anyone to help you create your portfolio; you have to set the direction and course. You can obviously ask for input – but you have to control the framework.
Others are able to diminish and destroy it without even trying to. You alone are the only person who can protect your brand.
