"I also used another technique that Doug Milsome [BSC] utilized on Full Metal Jacket [see AC Sept. 1987] where you throw the camera’s shutter out of sync to create a streaking effect from the top to the bottom of the frame. It’s a very interesting effect, but it’s also scary because there’s no way back [once you shoot with it]."
"Kaminski employed Panavision Platinum and Panastar cameras throughout the Private Ryan shoot, and had Samuelson Film Services in London prepare one unit with a purposely mistimed shutter in order to create the described streaking effect. Used in combination with a narrow shutter, however, the effect was negated as the shortened shutter interval fell within the moment that the film was in its stationary position. Due to this anomaly, however, the "streaking" camera could also be used for normal shooting provided that the shutter was set between 45 and 90 degrees."

"out of phase, I mean miss timing between shutter and movement, using on arri 435 or Panavision XL."
Do I understand correctly that this something that has to be done by a technician, so it's more about servicing and not about the certain camera?
Btw, most likely it's Arriflex 416 in the reference that I posted in the first message.
