Shutter speed indication
● Flickering occurs when shooting
under a fluorescent light. This
can be reduced by setting the
shutter speed to 1/50 in regions
where the power supply
frequency is 50 Hz, and to 1/120
in 60 Hz regions.
Shooting a Computer Display
The shutter speed should be set to variable scan mode. The variable scan mode is used to match the GY-
DV300's shutter speed with the variable scan frequency of computer screens, etc. When shooting a
computer screen with the camera, bright over-exposed horizontal stripes will appear in the picture if the
screen's scan frequency is faster than the camera's frequency, and dark under-exposed stripes will appear
if the screen's scan frequency is slower than the camera's scan frequency.
While observing the LCD screen, adjust the shutter speed until a stable image is obtained.
