No. I am not interested in receiving a service from someone. The phrase itself “take their portrait” indicates something is taken from someone: time, a part of their being, who knows. The term “portrait” entails capturing something about the individual. It can simply be a document of how someone physically looks. Going beyond that and seeking something more is when I really start caring, and I’d like to think that is when the subject starts caring. We both feel something. Some kind of exchange is occurring. I can’t really do that if it the motivation is financial.
