A portrait is a representation or portrayal of someone. An interesting portrait will not only draw something out of the subject, but draw the viewer into the image. I've heard countless times over the years as a photographer that the "eyes are the window to the soul". That's nice. Sounds cool. But capturing a person's exterior is hard enough. I don't believe you can photograph someone's soul, even through a "window". An emotion may be drawn out to the surface and the resulting facial expressions and body language will give you a clue as to what might be going on inside, but it's still only the visible outward appearance. Portrait photography is a challenge and also very rewarding emotionally, both to the subject and the photographer. It's so difficult to pick some of my favorites, but here's a few.
