Automatic Gain and ISO Limits (XC15)
Solution
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 [ Av ] , [ Tv ] or [ P ].
