Using the Built-in Flash

Using the Built-in Flash in the Creative Zone

When using a Creative zone mode, press the < > button to pop up the built-in flash.

: Select < > mode for full autoflash.

The shutter speed and aperture value are determined automatically, just as in < > (Full Auto) mode.

: Select < > mode to manually set a shutter speed slower than 1/200 second. The camera then automatically sets the flash aperture value to provide the proper exposure for your shutter speed.

: Select < > mode to manually set the aperture value.

In low-light conditions against a background such as a night sky, you can use automatic slow-sync settings to properly expose the main subject and the background. The main subject is captured by the flash, and the background is captured by long exposure using a slow shutter speed.

•Because automatic slow-sync shooting uses a slow shutter speed, always use a tripod.

: Select < > mode to set the shutter speed and the aperture value manually.

The main subject is exposed properly by the flash. The background exposure varies according to the shutter speed and aperture settings.

: The effect is the same as using flash in < > mode.
