Using the Built-in Flash

In a Basic Zone Mode

In a Basic Zone mode (except <Si,> 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.
