A Flash Control Mode (External) When an optional flash is attached and turned on, the Flash control mode (built-in) option is replaced by Flash control mode (external). A The Built-In Flash: Metering and Flash Control The camera uses i-TTL balanced fill-flash flash control with matrix, center-weighted, and highlight-weighted metering, standard i-TTL fillflash flash control with spot metering. In i-TTL modes, flash output is adjusted based on monitor preflashes emitted by the built-in flash when the shutter-release button is pressed. • i-TTL balanced fill-flash: The built-in flash emits a series of nearly invisible preflashes (monitor preflashes) immediately before the main flash. The camera analyzes preflashes reflected from objects in all areas of the frame and adjusts flash output for a natural balance between the main subject and ambient background lighting. • Standard i-TTL fill-flash: Flash output is adjusted to bring lighting in the frame to standard level; the brightness of the background is not taken into account. Recommended for shots in which the main subject is emphasized at the expense of background details, or when exposure compensation is used. 214 Menu Guide > C The Photo Shooting Menu
