MANUAL FLASH (M)
Normal TTL flash metering automatically
adjusts the flash intensity to provide the
proper exposure for the subject. Manual
flash provides a fixed flash intensity irre-
spective of the brightness of the subject
and the camera setting.
• In manual flash, the maximum flash power
is when the manual flash control is set to
1/1. Each step of the flash power level
corresponds to one aperture stop. For
example, changing the setting from 1/1 to
1/2, or from 1/32 to 1/64 decreases the
exposure by one stop.
• Manual flash operates in the camera's M
(manual) mode only. In other modes, TTL
measuring is selected automatically.
• As manual flash is not affected by the
reflectivity of the subject, it is useful for
subjects with extremely high or low reflec-
tivity.
