Exposure Time
The exposure time values of 1/200, 1/500 and 1/1000
(also 1/2000 for IT) of a second are used to capture
fast moving objects so that these can be played back
sharply in slow motion. The value selected depends
on the speed of the moving object.
Note
Increasing the exposure speed lowers the camera
sensitivity proportionally. With IT cameras shorter
exposure times increases smear effects
proportionally.
The exposure selection also includes lighting control
positions which can be used when shooting with
lighting that is operating at a different frequency to the
camera. There are two positions 50 Hz and 60 Hz.
Each of these positions can be varied further in a
range from -10 to +10.
To reduce flicker select the frequency closest to the
frequency of the lights and then vary the lighting
control in the system Install menu to obtain the best
result.
EVR - Enhanced Vertical Resolution [IT]
This exposure mode on IT cameras is used to increase
the vertical resolution especially for still pictures. The
exposure time is set to 1/25 for PAL and 1/30 for
NTSC.
