Studio Camera Study Guide The Studio Camera system consists of four interconnecting pieces of equipment: 1. 2. 3. 4. The Vinten Quartz two stage pedestal. The Vinten Pan and Tilt Head. The Hitachi Z4000W Camera. The Hitachi RU-Z2 & RC-Z3 Camera Control Panel. The Vinten Quartz Two Stage Pedestal allows one to move the camera in three planes: 1. Left/Right movement called “Truck” 2. In/Out movement called “Dolly” 3. Up/Down movement called “Pedestal” To steer the pedestal make sure the “brake lock” is off, point the “red steering direction indicator” on the “pedestal steering wheel” in the direction you wish to travel and apply a gentle push to the base of the pedestal. To pedestal up or down make sure the “pedestal column lock” is off then pull up or push down the “pedestal steering wheel” in the direction you wish to move. STUDIO CAMERA STUDY GUIDE  The Vinten Pan & Tilt Head controls the movement of the camera. Panning is the action of moving the camera right or left. Tilting is the action of moving the camera up or down. The head has a “Tilt Lock”, a “Pan Lock”, a “Tilt Drag”, and a “Pan Drag”. The Pan lock should always be unlocked. When using the camera both the Pan and Tilt locks must be unlocked. Always lock the Tilt lock when leaving the camera unattended! The Pan and Tilt drag apply resistance to the action of the head allowing smoother movement. The Hitachi Z4000W Camera has four areas that the camera operator must know: 1. 2. 3. 4. Power switches and Filter selection. Lens functions. Viewfinder operation. Focus and Zoom controls. Power 1. Make sure the Power Select Switch is set to CCU/VTR. Found on the lower back left side of the camera. 2. On the lower front left side of the camera locate the Power Switch and switch it to CAM ON, VTR:STBY. Notice the LED is red. If the LED is green camera power is supplied but the camera is not on. STUDIO CAMERA STUDY GUIDE  3. The Filter Wheel is used to compensate for various lighting temperatures. Filter #1 is for 3,200K light (Studio), Filter #2 is for bright outdoor light, Filter #3 is for cloudy outdoor light, and Filter #4 is a cross filter for studio use. Make sure the Filter Wheel is set to position #1. Lens All Zoom lenses have five main features: 1. 2. 3. 4. 5. Focus Ring Zoom Ring Iris or Aperture Ring Macro ring Flange Back Adjustment The Focus Ring is controlled via the Flexible Focus Control Unit located on the left Pan Handle. Turn the grip clockwise to focus on an object moving closer to the camera and counterclockwise for an object moving away from the camera. The Zoom Ring is controlled via the Zoom Servo Handle located on the right Pan Handle. The Rocker switch is pressure sensitive allowing one to zoom faster or slower. STUDIO CAMERA STUDY GUIDE  The Zoom Ring can be manually controlled by setting the zoom select switch to MANU and rotating the Zoom Ring by hand. DO NOT ROTATE THE ZOOM RING BY HAND IF SELECTOR SWITCH IS SET TO SERVO. This will damage the zoom motor and render the zoom function useless. The Iris Ring is controlled by the Camera Control Unit in the control room. Make sure the Iris Select Switch is set to “A” for camera control unit operation. The Macro Ring is used to focus on objects too close to the camera for normal focus operations. See Manual. The Flange Back Adjustment screw is used to adjust the back focus of the lens in relation to the CCD’s. If the camera is out of focus on the wide end of the zoom inform the Lab Staff or Director. Viewfinder The Viewfinder is an under-scanned monitor. This enables one to see the entire picture from one edge to another. The safe composition area is outlined with a white border. Only the picture within this border will be seen on a television set. On the left and right of monitor are tally lamps. These will light up when the switcher selects the camera. The viewfinder has several controls. The Front Tally Switch turns on or off the tally light on the front of the viewfinder. The Aperture control allows the operator to adjust the viewfinder to display a sharper leading and trailing edge to the picture enabling easier focus. The Brightness and Contrast controls allow one to adjust the viewfinder to their own parameters. The “T” handle located under the viewfinder allows one to tilt and/or pan the viewfinder. Unlock the “T” handle by turning it clockwise. Position the viewfinder and relock the handle. STUDIO CAMERA STUDY GUIDE  Headset Control The Headset Control is located on the left side from the back of the camera, labeled Talk. Adjust the volume and Talk function. Camera Control Unit (CCU) The CCU enables the operator to control several functions of the camera. 1. Control Lock 2. Cam/Bar 3. Iris Selector 4. Detail 5. White Balance Selector 6. Auto White Balance 7. Auto Black Balance 8. Iris Control 9. Master Black Control 10. Enable Gain & Black Selector 11. Red & Blue Gain 12. Red & Blue Black 13. Gain 14. Scene Storage (4 scenes) After powering up the CCu and camera set Lock (1) to On. Set Cam/Bar (2) to Camera. Set the Iris Selector (3) to Remote. Set DTL (4) to desired detail (usually Var). STUDIO CAMERA STUDY GUIDE  Set White Bal (5) to Mem. With the camera shooting a white card push the A.WHT (6) button to White Balance the camera. To set Black Balance push A. BLK (7). To adjust the Iris rotate the Iris Knob (8). To adjust the Master Black rotate the M. Blk Knob (9). If cameras are slightly mismatched color-wise, press the Enable button (10), Carefully adjust the Red or Blue Gain pots (11) until camera matches the other camera. Black in the Red and Blue can also be finely adjusted (12). If Gain is required for low light situations select the appropriate amount. (13) Four separate camera scene settings can be stored in the Scene File. (14) To store a setting push Store and the scene file number where you wish to store the settings. To recall a stored setting just press the appropriate scene file. STUDIO CAMERA STUDY GUIDE
