For a backlit subject, the flash may fire to help lighten the subject's

mode (p.55). Other than the flash setting, the camera will shoot with
the same settings as with <A>.
The flash fired and the picture came out extremely bright.

photography, if the subject is too close to the camera, the picture
may come out extremely bright (overexposure).
In low light, the built-in flash fired a series of flashes.

Pressing the shutter button halfway may trigger the built-in flash to
fire a series of flashes to assist autofocusing. This is called the AF-
assist beam. Its effective range is approx. 4 meters / 13.1 feet.

unnaturally dark.
The shadow of the lens barrel was captured in the picture because
the subject was too close to the camera. Move further away from the
subject and shoot. If a hood is attached to the lens, remove it before
taking the flash picture.
