You, as the able photojournalist, are a kind of historian, reporting the contemporary scene. But this is reported from the front view, not the back. In most things the camera must be there first. It is a leader, showing the way, informing, and interpreting. Even in commercial advertising art, it opens doors to new luxuries and new uses of products, thus selling and motivating.
Life is never the same two minutes in a row.
Look at the perplexities of this decade, such as changing morals, concern over big government, fear of war, crime and violence, population explosion, economy, ecology, etc. Each new machine, change in our social system or lifestyle brings new complexities. For example, when Orville and Wilbur started playing with the airplane no one would even imagine that they would be used to transport masses around the world. Progress is always one step ahead of man's acceptance. Man is always a little behind in the full use and approval of the new structures.
