RECORDING MODE
FLASH METERING
Two flash-metering methods are available: ADI and pre-flash TTL. The flash metering-
mode can be changed in the basic section of the recording-mode menu (p. 80).
ADI flash metering - Advanced Distance Integration. This metering mode combines
distance information from the autofocusing system with information from a pre-flash
exposure. Unlike conventional TTL flash metering, ADI is not influenced by the
reflectance of the subject or background ensuring optimum flash exposures.
Pre-flash TTL - calculates flash exposure with a pre-flash only. This mode must be
used when using close-up filters or filters that reduce the amount of light entering the
camera such as neutral density filters. Pre-flash TTL must be used when a diffuser is
attached to the built-in flash or an external flash unit.
The camera will automatically switch from ADI metering to pre-flash TTL when a low-
contrast subject is preventing the autofocus system from focusing. If the autofocus
system cannot lock on the subject, press the AF/MF button and manually focus; the
ADI metering will remain in effect.
This camera does not have a preset flash sync speed. When calculating the exposure
in program (P) or aperture-priority (A) exposure mode, the shutter speed will not fall
below the camera-shake limit (p. 15). When using shutter-priority (S) or manual (M)
exposure mode, any shutter speed can be used in the exposure.
For a list of compatible Minolta accessory flash units and for information on accessory
flash operation, see page 138. Because both flash modes use a pre-flash, slave
controlled flash units cannot be used.

METERING MODES
Multi-segment
Spot
Center weighted
An advanced metering system appropriate for
almost all photographic situations.
Averages luminance values from the entire
image area with a bias toward the center of
the image.
The icons indicating the metering mode are displayed on the monitors only. Do not
confuse these icons with the focus signals (p. 68). The metering mode is changed in
the basic section of the recording-mode menu (p. 80). When center-weighted or spot
metering is selected, pressing the shutter-release button partway down will activate the
exposure system, but will not lock the exposure; the AF/AEL button must be used.
Multi-segment metering uses 300 segments (256 segments for the DiMAGE 5) to
measure luminance and color. This data is combined with distance information to
calculate the camera exposure. This advanced metering system will give accurate
worry-free exposures in almost all situations.
Center-weighted metering is a traditional metering method in silver-halide cameras.
The system measures light values over the entire image area with emphasis given the
the central region of the scene.
Spot metering uses a small area within the image to calculate
the exposure. When this mode is selected, a small circle will
appear in the middle of the live image indicating the measuring
area. The spot allows precise exposure measurements of a
particular object without being influenced by extremely bright or
dark areas within the scene.
