I know someone in Hollywood film production. In the past, I have been told that mostly film is used. However, that was nearly two years ago. I believe if I asked again, I would be told that things have changed in the last two years...I believe a lot of the cinematography is moving to digital capture. Some of this was intentional migration because just like in photography, some of them like digital capture. Some of it is to reduce costs. Some of it is to film in ultra low light. Some is due to the need for 3D imaging or certain special effects that make digital an easier capture method. Some of it was due to natural disasters that made it hard to get film developed. But it's happening. It's probably analagous to 2003-2004 in the photography world right now. Sure, some directors continue to shoot motion pictures--or even TV shows--on film, just as some pro photographers continue to shoot film for wedding or documentary work or portraiture... But the transition is happening, and looks like it can't be stopped. And now Kodak...this can't help it. As a film user, this is not a good feeling for me.
An undeniable paradox: To think that there is any such thing as an absolute rule is at worst naïve, and at best, shortsighted. There is no such thing as an always-true, all context- or situation-salient, absolute rule that always holds true including this one!
