A photo of my sister. She is strongly against having a camera pointed at her. Perhaps a stint as a child model for Zellers scarred her. Well I have a policy that you can't be related or friends with me unless you are willing to help me out and let me take your portrait (see Why am I Marrying him? for the best example of this policy). My sister was the last one to give in to this request. Now I am allowed to take her photo but it must be at lightning speed and I can't ask her to do anything too specific. I recommend this policy for all photographers. Relatives are often very concerned about someone like me who makes a living off of their photography (I think that they don't believe that this is really possible). So I always say how they can help me most is to let me take their photo.
