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

irrespective of the brightness of the subject and the camera setting.

 In manual flash mode, 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. Changing the setting by one stop, for example from 1/1 to 1/2, is

equivalent to decreasing the aperture one stop, for example from f/4 to f/5.6.

 Manual flash can only be used when the camera is in the M mode. In other

modes, TTL measuring is automatically selected.

 As manual flash is not affected by the reflectivity of the subject, it is convenient

for use with subjects with extremely high or low reflectivity.
