3Std Scene File button

The standard scene file button is a momentary button which, when pressed for two seconds, recalls the standard scene file video values. These values do not take effect immediately if the camera is on air; they take effect when the camera goes off air.

Refer to the Appendix for the default values of the factory defined standard scene file. Refer to Section 6 to find out how to define and assign a standard customer scene file.

If the optional Smart-Touch™ feature is installed and switched on, pressing the Std button for two seconds displays a list of files in the viewfinder menu. Files are listed under the Lighting, Creative, and Matching categories. The standard settings file is also available. Use the Rotary control and Select switch at the camera front to recall a file.

The memory positions can be filled with measured values using the automatic white balance switch at the front. Indicators in the 1.5-inch viewfinder light to show which position is selected. None of these indicators light when AWC is selected, but the non-standard indicator (!) lights.

-Gain is - (-6, -3dB)

+Gain is + (+6, +9, +12, +18dB)

++Gain is ++ (+9, +12,+18, +24dB) + and ++ Gain is +++ (+30, +36dB)

using the +++ position.

8Clean Scan button

When shooting computer monitors with higher frame frequencies than the camera use the Clean Scan function to avoid horizontal bars in the picture.

Press the Clean Scan button for two seconds to directly access the variable exposure (clean scan) function. Use the rotary control to change the value and so remove the noise bar. When you are finished shooting the monitor press the Clean Scan button for two seconds to switch off the Clean Scan function.

When the Clean Scan function is on, the non-standard indicator in the viewfinder lights. Refer to Section 5 for more information on shooting screens.

9White Balance switch

This momentary switch is used to start the automatic white balance process. The camera, when pointed at a white area in the centre of the picture, measures and stores a colour temperature setting in the FL, AW1 or AW2 memory position.

The white balance switch only operates if the colour temperature is set to the FL, AW1 or AW2 position. Refer to Section 5 for more information on how to use the automatic white balance.

Note

Black balance is not necessary with this camera because of the continuous automatic black control circuits.
