Autofocus to IMAX!

I wrote a while back about shooting an entire movie with autofocus..

Autofocus for an entire movie

On Saturday I saw the results projected and not just projected but on an IMAX screen!
This film was never intended to be seen this size, we knew we were shooting for TV screens.
I was sitting in the front row, not by choice but I had to be there so that I could quickly take part in the Q&A afterwards.

So, did it work?
Well yes, no more soft shots than any other movie I’ve seen on the large screen recently. In other words not a lot at all.

The entire movie was shot either with autofocus and face recognition or controlled via a tablet with simple finger presses.
We learned how to quickly switch between modes while we were shooting and also what we could do during a shot.
The one thing we thought was missing that would have helped a lot was a couple of preset positions that we could load as escape positions. Preset so that if the face recognition lost track during a fast move towards camera we had emergency goto’s in the most important positions. Happily Canon have now added this facility.

I said at the time that I probably wouldn’t do a movie like this again, having looked at the results on an IMAX screen I now think that this is the future.
At present you are limited in your choice of lenses and camera.  Canon are moving in this direction faster than others. I can see how they could, if they wanted, interface the /i info from say Cookes to the cameras internal software and an external focus motor and so enable this for any lenses with /i.

As we move to bigger and bigger sensors we need to look very closely at this kind of technology.
There are other solutions out there but they are all expensive and somewhat complicated.
This was very very simple, even a cinematographer could operate it!
