questions about varicam

[Tony]

Various “ASA” rating will result depending on numeorus internal DSP settings in the camera. Best advice is to conduct a test by employing an experienced/qualified video engineer or video controller to set up your camera and verify the “ASA” rating. Tools required will be a HDSDI waveform monitor (ie Leader 5700A or 5750, DSC cam align chart, two tungsen lights).

As far as reducing noise in the shadow areas avoid shooting with “F” or prior versions of Varicam instead use the “H” model and dark compression. FYI HDX-900 is much cleaner than “F” as well as prior versions of the Varicam which overall I find quite disappointing in terms of overall noise in the shadow areas.
