As a portrait photographer, I usually seek out soft, but directional light.  The soft light is flattering to humans and the right direction of light shapes and forms the features of face and body.  But my favorite rule of photography is to break the rules of photography.  Sunny summer mornings is when I am looking for some open shade, which I did do in this session, but I could not resist that wall  with the shadows playing on it, so I took a few, and they were my favorites out of the session.
