When to adjust aperture, shutter speed, and gain manually
When selecting one of aperture, shutter speed, or gain to be adjusted manually and
leaving the remaining two in automatic adjustment, the remaining two automatic
settings adjust their values based on the value of that one manual setting.
In the following cases you should obtain better results by adjusting setting manually.
