[P Programmed AE]+
The camcorder automatically adjusts the
aperture and shutter speed to obtain the optimal exposure for
the subject.
[Tv
Shutter-Priority AE]
Set the shutter speed value. The cam-
corder automatically sets the appropriate aperture value. Use
faster shutter speeds to record subjects moving quickly; use
slower shutter speeds to add motion blur, emphasizing the feel of
movement.
[AV
Aperture-Priority AE]
Set the aperture value. The camcorder
automatically sets the appropriate shutter speed. Use low aper-
ture values (larger lens opening) to softly blur the background in a
portrait; use high aperture values (smaller lens opening) to get a
wider depth of field, giving a sharp focus all throughout a land-
scape.
