Why are we so interested in making art about each other?
What are some things that portrait artists are trying to talk about?
How are photographic portraits different from portraits in other media?
For a long time making portraits was a way to record one's existence. As it evolved it became a way to allow the masses to understand stories, especially in religion. It then became a commodity for those that were rich to record themselves, their power, and their wealth. By the early 1900s when photography was slightly more affordable it then became a way to document a person's existence again, particularly during wartime. Now when we think of portraits it's more of an artistic experience, it's less about the portrait itself and more about the way it was made and what it signifies.
In early commissioned portraits wealth and power were depicted but today they are used for several different reasons. For some it's leaving a mark on the world and for others it's about exploring the different ways to make the portrait itself whether it's different media or playing with the lighting. In photography it tends to be a recording of the person and maybe an exploration of that person's personality on film.
You can create multiple copies of a singular image and you have the ability to take multiple images at a time. This means there are so many options for the photographer once they have shot their subject as opposed when a painter makes a portrait. You also have more of an ability to control the outcome with photography because you are able to immediately see the results.
