Ever wonder where some of the things we were promised in the future have gone? Our cars still dont fly (yet), and so much of what we thought would be a part of our lives have simply not materialized. Then too, many, many things we never saw coming are now so ingrained in our lives, like smart camera phones, and tablets. Photography itself has had no less a profound change as everything we now see. That so many now have such powerful tools to create images and disseminate them to the whole world is deeply profound.
Most of history happens with the people involved unaware of just how historic their experiences are. Only with some distance in time will we be able to comprehend just how significant what we do today in photography is. It actually may be a blessing we are not so aware of how big or important things will be. I remember a radio interview years ago with Justin Hayward of the Moody Blues. He had written the seminal hit of the group "Nights In White Satin" when he was 19-years-old. The interviewer asked if he would have written the song if he had any idea of just how big of a hit it would be. Justin replied "No, if I had any idea of the enormity of the song, I would have been too scared to write it."
I believe the less time we spend thinking about the significance of what we do, the better we'll be able to create significant work. Thinking too much about "Where are we going?" actually limits where we may actually go.
There is more we do not see that may actually be... one day.
