Exposure
The software has automatic and manual exposure control options. When Auto
Exposure is selected on the “Video Settings” window, the software adjusts the
brightness. You can use the manual mode to adjust the brightness. If you adjust
the brightness manually, you will have to adjust the brightness each time the
lighting conditions change.
Shutter Speed
The shutter speed is determined by your software’s video setting. Use the
information in the following table to select the best frame rate for your particular
need. For example, for low light conditions, select a slower shutter speed range
(set Zoom at Wide and Quality at High) on the “Video Settings” window.
When taking pictures of moving objects, select Stop Action to limit the shutter
speed to 1/40 second (maximum) and reduce motion blur.
