1. Determine correct aperture for the backlit subject
(according to method on page 25) by referring to the
SB-20’s aperture selection/distance range panei,
then set both the aperture index and the aperture on
the iens.
2. Frame the background in the camera viewfinder and
turn on camera meter to determine proper shutter
speed for the aperture set on the lens. The shutter
speed must be equal to or slower than the flash sync
speed—without a proper shutter speed you cannot
perform fill-in flash photography in A mode.
3. Set the shutter speed from step 2 on camera’s
shutter speed dial.
4. Set the flash mode selector to A, turn on the flash
unit and take the shot.
With a strongly backlit subject, perform fill-in flash
photography in M mode.
