Colour Temperature selector (White Bal.)
This up/down scroll selection switch allows a choice
between three preset colour temperatures:
• 3200K (3.2K) - for studio lighting conditions
• 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. 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.
Colour Bars switch (Bars)
The Bars switch turns the colour bar test signal on and
off. The lens iris closes automatically when the colour
bars are switched on.
Gain selection switch
This up/down scroll selection switch gives a choice of
five master gain settings. The values for these settings,
except 0 dB, can be set in the Install menu of the
camera systems menu (refer to Section 6). The
indicators in the 1.5-inch viewfinder light as follows:
- Gain is - (-6, -3dB)
+ Gain is + (+6, +9, +12, +18dB)
++ Gain is ++ (+9, +12,+18, +24dB)
+ and ++ Gain is +++ (+30, +36dB)
+ and ++ Gain is +++ (+30, +36, +42dB)[IT]
Note
Reduce crispening (peaking) in the viewfinder
when using the +++ position.
Clean Scan button
When shooting computer monitors with higher frame
frequencies than the camera use the Clean Scan
function to avoid horizontal noise 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 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.
White 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.
Exposure Time switch
This up/down momentary switch gives a choice of
eight exposure time settings. These are:
Nom. - nominal setting
Cl. Scan - for shooting computer monitors with higher
frame frequencies than the camera
Crt - for shooting sync-locked monitors [FT]
EVR - enhanced vertical resolution position [IT]
1/200 - for fast moving objects
1/500 - for fast moving objects
1/1000 - for fast moving objects
1/2000 - for fast moving objects [IT]
50 Hz - shooting with 50Hz lighting (adjustable)
60 Hz - shooting with 60Hz lighting (adjustable)
If an exposure time other than nominal is selected, the
non-standard indicator (!) in the viewfinder lights.
