Automatic Gain and ISO Limits
Depending on the brightness of the surroundings, the camcorder will automatically raise the gain or ISO speed
to try to get a brighter picture. Because doing so can lead to video noise, you can select a maximum limit for
how high levels are raised. These limits are referred to as the automatic gain control (AGC) limit and auto ISO
limit. Shooting with a smaller limit is useful as it results in a darker picture but less noise. This function is available
when the shooting mode is set to ’, ‚ or “.
Because only the ISO speed can be adjusted for photos, in mode, press the MENU button and start the
procedure below from step 4, selecting the options for ISO speed.
