Confirm that the ready-light is ON, then release the
shutter to fire the flash.
In 3D Multi-Sensor Balanced Fill-Flash operation with cameras in Group I,
press the "M" button to change the flash mode indicator from tØ to
t in order to cancel Monitor Preflash*. This will avoid exposure errors
when removing the SB-27 from the camera. (See page 63.)
*See page 86 on Monitor Preflash.
For example, with a subject located 0.5m (1.6 ft) away using ISO 100
film, this is how you would calculate the aperture:
* An aperture of f/8 is suggested. We recommend using the smallest
possible aperture ( f/11 or f/16).
With a very light or dark-toned subject, you may not obtain a
correct exposure due to the subject's reflection factor. Use
exposure compensation to ensure correct exposure.
