Video Functions
Std 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.
Black Stretch switch
This switch when set to the On position, starts the black
stretch function. This function gives more detail in the dark
areas of the picture. Set the switch to Off to switch off the
function. When black stretch is switched on the non-
standard indicator (!) in the viewfinder lights.

This up/down scroll selection switch allows a choice
between three preset colour temperatures:

•
5600K (5.6K) - for outdoors, clouded conditions
•
7500K (7.5K) - for outdoors, clear blue skies
three memory positions:
•
FL- memory position for fluorescent light
•
AW1 - memory position 1
•
AW2 - memory position 2
and an automatic continuous white position:
•
AWC - continuous measurement (2.5K to 20K)
The memory positions can be filled with measured values
using the automatic white balance switch at the front.
