Our second to last Circus session today, and it was defiantly one of the most interesting, Studio Camera’s. Heres what I wrote about it in my Circus Report:
Studio Cameras are in some respects simplified versions of PSC cameras, as they don’t have the ability to record directly or capture sound. Studio Cameras are operated by a single operator in the studio and a secondary racking operator in the gallery. The racking operator is responsible for the exposure, white / black balance and the colours. If each camera operator had these controls, the picture wouldn’t be as consistent as if it was operated remotely by one.
We were trained on the Sony HXC100 HD Camera’s, with four being mounted on Vinten Pedestals and the fifth on a non-pressurised Pedestal. The operation of the zoom and focus has moved from the camera body (PSC) to two wired remotes on the pan and tilt handles of the Pedestal, with the exception of number 5, which is designed to be used as a hand held and its pedestal, is only a place to keep it when not in use.
Camera 5 also has a Wide Angle, which again changes the perspective of the studio for the viewer, with this lens the studio looks larger than, when it is viewed with one of the other 4 camera’s which all have the same narrower lens. Graham Reed2 also went through a great deal on perspective and depth of field and how it can greatly effect an images composition. The great example he used was a line of tree’s and showed how using different focal lengths you could make the trees look closer together (narrow angle) or further apart (wide angle), than they truly were.
Another day, another circus Session this time we were learning about location sound. this is what i wrote about it for my Circus Report:
Locations sound works hand in hand with location camera’s providing additional sound capabilities to the single camera, for example an interview situation that required two personal mic’s could be mixed together before being fed to the camera as stereo or mono line level mix. Location mixers often have 2-4 inputs and can either mix in stereo or dual mono. Location mixers normally have better Microphone pre-amps than Camera’s, which in turn provides better sound quality, as the mixer is outputting at line level (0db) and the camera won’t apply any more amplification to the signal.
Some microphones require batteries or phantom power (+48v) to operate; these mic’s are a form of capacitor mic’s are much more sensitive than standard dynamic mic’s that don’t require power to operate. Most cameras and mixers can supply phantom power to these microphones.
When setting up for a shoot, you can use the tone that the mixer is supplying to the camera to help setup the record levels on the camera. Tone should be set just below the 0db mark as this allows some “head room” before the camera starts to clip the signal should you go above the tone volume.
