"...more about me..."

I agree in some ways with this quote and disagree in others.  While I do agree that whenever you create a picture or work of art you impose your own meanings and interpretations to it.  This can easily be done with portraits, so that the portrait reflects how you view that person.  On the other hand, the picture is still of that person and others will interpret the meaning of the portrait differently than you would.  No matter what meaning you try to impose it will be interpreted differently and that's when the photograph is more about the subject.
