As a filmmaker I like to make portraits because they are personal and unique. Everyone has a vision, their own qualities and their own working method. Why you believe in yourself, your product or service is also the reason why others believe in you.
I think it's great to capture this piece of experience through a video portrait. By showing yourself as you are, you create trust and reach the people who also believe in your vision. Because by portraying your unique story, you touch the heart of your ideal customer.
