A common complaint is that the picture comes out 'dark' when taking flash photos indoors. This is often the result of TTL (through the lense) metering of the flash exposure by the internal controls of the camera. The flash is regulated only to the subject and back to the camera during which time, the camera controls the amount of light returned from the subject for proper exposure. This often means the background will be darker than the subject and is especially evident when the subject is standing in a room with lots of space behind them. There are some solutions to light the room behind the subject: first, use bounce (when ceiling is low enough) to send some light to the back of the room, or use a slower, longer shutter speed to allow exposure time for weak light in the background. This is sometimes called the "Night Portrait" mode on many cameras and will require a tripod or stable support to eliminate camera shake during that longer exposure. The slower shutter speed allows the camera to capture weak light in the background, and the flash still properly exposes the subject.
