Ideal for filming such slow-motion scenes as the deployment of vehicle airbags, cereal falling through frame, small-scale explosion effects, the classic water droplet and crown effect, a close-up of a golf ball being hit by a golf club and bullets exiting the barrel of a gun.

Important 4B Camera Technical Information

We enjoy your business and we would like to make the high speed portion of your shoot a trouble-free experience. Please be sure this information is forwarded to the appropriate crew members such as the Assistant Cameraman, Gaffer and the Director of Photography.

* The 4C camera uses a rotary prism (it is not pin-registered). When shooting with a rotary prism camera, the image will have a slight weave and float to it. It is not something that is extremely noticeable, but we do not suggest using it for any composite, matte or blue screen work. Post-production stabilization may be possible and necessary in some cases. Dedo Weigert Film GmbH will not be responsible for any costs related to such correction.

* It has a 72 degree fixed shutter angle (the DP & Gaffer should be made aware of this since it will affect lighting requirements).

* Using the reduced shutter angle while running high frame rates will result in extremely short exposure durations, which may require compensation for reciprocity failure. The 4C comes with an exposure compensation chart, which takes into account the 72 degree fixed shutter angle, frames per second and the light loss for the reflexing pelical. This chart does not take into account reciprocity failure. Please review film data sheets to determine the amount of compensation (if any) is required.

* While 4C frame rates are extremely accurate, it is not a crystal sync camera and should not be used with standard HMI lights or to film video or computer monitors.

* It will not sync up with any strobe light systems.

* Since the image is relayed through a rotating one inch thick prism, it is always best to light with more contrast and lean towards over-exposure rather than under-exposure.

* Try to avoid shooting directly into high intensity sources. When shooting into bright lights you may encounter an apparent flicker related to stray reflections in the image path.

"I use the Photo-Sonics high speed cameras because of their unequaled history of dependability. Many of the effects we do are one-time-only events: blowing up a set or jumping a car. Repeats are expensive, if not impossible in the tight delivery schedules we have these days. I need to know that the shot will be 'in the can' on the first take. The Photo-Sonics cameras have never let me down."
- Bill Bennett, Director of Photography
