Name three of each and explain the difference between, Camera and Directors instructions.
Camera instructions are Pan, Tilt and Zoom, which is electronically operated by the camera person, while Directors instructions are Standby, Action and Cut and are manually carried out.
When you open the iris of a camera, what does it do to the picture?
The iris or aperture of a camera controls the amount of light which enters the camera. Therefore the opening of the aperture would increase the brightness of the image when shot.
What is the other option for shooting? And what does it mean?
4:3 is another option for shooting, it is termed the aspect ratio, which describes the ratio of a pictures width to its height. 4:3 means that for every four units of width, the picture will be three units of height.
What is AGC, and what does it do?
AGC stands for Automatic Gain Control, which means that the camera will continuously adjust the audio levels so that loud sounds won't overload and distort, and soft sounds won't go unheard.
What is white balancing a camera, why do you do it, and what does it accomplish?
White balancing a camera deals with the adjustment of the camera settings to ensure all colours in the scene be represented consistently. It can be adjusted automatically by the camera or manually by selecting pre-sets or aiming the lens at a totally white surface or grey.
Apart from white balance, what should you check before each new scene?
Before each new scene, the aperture and volume level must be checked, before you proceed to shoot.
