Well, we have all- all that footage over the years that was shot in 16mm, beautiful color. A year or two ago I, I advanced my technology, I think, by beginning to use a video camera. And- actually it was only a year or so that I used the camera- the video- on this project. But there are many reasons to make it- to have made that choice. One of them is that with this little camera, the tape will run without interruption for an hour so that at no time would I expect that I have to lose a shot or part of it because I only have ten minutes of a run, which is the case with film. And the camera that I've been using is much smaller, less obtrusive; there are economies as well. The- I'm all the more excited with the new technology that'll add more possibilities for capturing more intimacy with whatever I film for "The Gates" project.
