Sony MVC-FD83 User Manual

You can select one of six PROGRAM AE (Auto Exposure) modes to
suit your shooting situation, referring to the following.

For recording subjects with backlight or strong contrast between
subjects and background. Use this mode to take a picture with
the appropriate exposure for just the point you want to focus on.

For making subjects brighter in insufficient light.

For recording a dark picture more brightly, or making the
movement of the subject brighter seem lively.

For recording subjects in dark environments such as sunsets,
fireworks, neon signs, or general night views.

For distant subjects such as mountains behind an obstacle such
as a window or screen.

For changing the subject to focus on quickly and simply (from
close subjects to distant subjects). Or, for recording with flash in
a dark place  where it is hard to bring the camera into focus.
