Portraiture is hard to define. Whole books have been written on the subject. I believe a portrait gives visual meaning to some element of a person's character. It need not be literal – a uniform or a specific action such as a batter’s swing. It can also be figurative – an expression, the relationship of the person in a space, or body language. Most but not all portraits are made in controlled situations. But sometimes serendipity intervenes. A moment occurs in front of me that expresses more than whatever is literally happening. That moment can help define who someone is.©The Oregonian.
