It's my belief that film will be very much redundant in the very near future. I recently suggested to a client, a high-street super-chain selling high-end fashion, that we shoot an ad on 35mil as they were after a retro look and they weren't interested. The budget was there but they thought it was "too old-school". So I turned up at the shoot with an iPhone with a shallow depth of field rig and they loved it. The results were great too. Very 35mil. Needless to say they, and I, were happy. So was my bank.
In my own personal films I tend to use what ever is best suited to the job. Sometimes it's a 5D, sometimes it's an iphone. What ever I choose I always get the required results. Interesting post though. Looking forward to getting to know the community here.
Cheers yeah,
