While I do shoot headshots for websites, I prefer a somewhat more complex portrait session that includes many different kinds of views.  My reasoning is most people are not unidimensional and have many different aspects to their personality and character.

Below are a few examples from a recent portrait session that is 'typical'.  There are both studio images as well as outdoor images.  This approach creates a very rich collection of pictures that the client will be able to use in many different ways.
