Focussing in Post

The idea of a camera that will allow you to select what is and is not in focus AFTER taking a photo is not a new one. There is a company already supplying surveillance cameras with this ability and the franken-camera has been living in a University for a while. However by the end of the year it may be a commercial reality thanks to a new company known as Lytro.

What will this do to professional photography? While some people may leap to the conclusion that it will spell the end of professional photography as we know it I believe that this is far from the truth.

1) It's like RAW
Photographers love RAW because it lets them do more in post. It lets them adjust the exposure and the colour balance after taking the photo. The addition of focus to this mix will just be another tool in the belt.

2) Professional Photographs are about more than focus
The key point for me has always been framing, focus is an additional piece of flavouring.

3) It's a whole other kind of photograph
The ability to dynamically change the focus point in a photograph will allow greater user interaction. Such images will probably become popular for companies selling products or experiences. However it is less likely to be used by companies selling a story - maintaining focus control will maintain story control.
