Using the Built-in Flash
In a Basic Zone Mode
In a Basic Zone mode (except <Sk> and <^>), the built-in flash pops up
and fires automatically when necessary in low-light or backlit conditions.
In a Creative Zone Mode
In a Creative Zone mode, you can use the built-in flash at anytime
regardless of the existing light level. Just pull up the built-in flash head
before taking the picture.
p
: Use this mode for automatic flash photography. The flash sync speed
and flash aperture are set automatically as with the <D> (Full Auto)
mode.
Tv
: Use this mode if you want to set a flash sync speed slower than
1/125 sec. The camera will set the flash aperture automatically to
obtain a correct flash exposure.
Av
: Use this mode if you want to set the flash aperture. In this mode, you
can obtain a balanced exposure between the subject and a dark
background (night scene, etc.) with a slow sync speed set
automatically by the camera. The flash illuminates the subject while
the background is exposed with a long shutter speed.
• Be sure to use a tripod when a slow sync speed is set.
M
: This mode enables you to set both the flash sync speed and flash
aperture. The subject is properly exposed with the flash and the
background is exposed with the flash sync speed and aperture you
have set.
DEP ; This mode gives the same flash result as the <P> mode.
