A less flippant answer:
We are working with very limited information anyway. A two dimensional representation is usually not enough, and often shows the photographer's skill as much as anything. You need specialized lenses to get color balance right, and it's difficult to capture texture and color at the same time. And even then, different subjects photograph differently. There are people who are very photogenic, but in person, seem awkward and ungainly, and vice versa. A person moves in three dimensions through time. If a static, two dimensional photograph were enough, there'd be no need to visit a tailor. You'd just send in pictures of yourself in your skivvies, standing beside a meterstick, and you'd be good to go.
Given the limitations of this medium, then, which outfit do you find more attractive. Which poster do you find more stylish?
