Setting the aperture in bounce fl ash operation
• In bounce flash, there is a light loss of 2 to 3 stops when compared with normal
flash photography (with flash head adjusted to horizontal/front). Therefore, you
should use a two- or three-step wider aperture (small f-number), and adjust it
according to the results.
• When the flash head is adjusted to other than the horizontal/front position, the
flash shooting distance range indicator on the SB-900 disappears. To ensure
correct exposure, first confirm the flash shooting distance range and aperture
with the flash head in the normal position. Next, set this aperture on the camera.
