This provides the effects listed below compared to those with direct light from a flash unit: • Overexposure to a subject that is closer than other subjects can be reduced. • Background shadows can be softened. • Overexposure of faces, hair and clothes can be reduced. • The shadows can be softened further using the Nikon Diffusion Dome.
Setting flash head tilting/rotating angles, and choosing a reflecting surface Flash head tilted up 75˚ while rotated 180˚ White ceiling E Functions • Good results are most easily achieved when the flash head is tilted up to use the ceiling as a reflecting surface. • Rotate the flash head horizontally to get the same effect when the camera is held in the vertical position.
Bounce Flash Operation Nikon Diffusion Dome • By attaching the included Nikon Diffusion Dome over the flash head, light can be further diffused during bounce flash photography to create extremely soft light with virtually no shadow. • The same effect can be achieved with the camera in either horizontal or vertical position. • Light is more effectively diffused when the built-in wide panel is used.
Zoom head position indicator • When the Nikon Diffusion Dome is attached, the zoom head position is automatically set depending on the camera’s image area and illumination pattern. The zoom head position is set at 12 mm, 14 mm or 17 mm in FX format, and 8 mm, 10 mm or 11 mm in DX format. (0H-17) • The illumination pattern can be changed with function button 1. (0E-3) Taking a picture with bounce flash Set the flash mode.
Bounce Flash Operation t Setting the aperture in bounce flash operation • In bounce flash, there is a light loss compared with normal flash photography (with flash head adjusted to the forward-facing position). Therefore, a two- or three-step wider aperture (smaller f-number) should be used. Adjust according to results. • When the flash head is adjusted to other than the forward-facing position, the SB-910 LCD does not display the effective flash output distance range indicator.
Taking Close-up Photographs E Functions When the flash-to-subject distance is less than approx. 2 m (6.6 ft), tilting down the flash head is recommended to ensure sufficient illumination of the lower part of the subject in close-up photography. • The bounce-down icon appears when the flash head is tilted down. • With the built-in wide panel, the flash 0° from the SB-910 is diffused. This softens 7° shadows and prevents overexposure on faces, etc.
Taking Close-up Photographs Setting the built-in wide panel Carefully pull the built-in wide panel all the way out and position it over the flash panel. Slide the bounce card back into place inside the flash head. Functions E • To replace the built-in wide panel, lift it up and slide it into the flash head as far as it will go.
Taking close-ups with bounce-down flash Set the SB-910’s flash mode. Position the built-in wide panel. Confirm the flash-ready indicator is on, and then shoot. t If the built-in wide panel is broken • The built-in wide panel may break if subjected to strong knocks while on the flash head. • In this case, contact your retailer or Nikon representative. • If the built-in wide panel is broken, the zoom head position cannot be set to the desired position.
Flash Photography with Color Filters Color compensation filters, a fluorescent filter and an incandescent filter, are included with the SB-910 for use with flash photography under incandescent/ tungsten and fluorescent lighting. • For more details on color compensation filter effects, see the separate booklet “A collection of example photos.” • Color filters (Color Filter Set SJ-3 and Color Filter Holder SZ-2) that change the color of the light emitted by the SB-910 are available separately.
Check the LCD. • Filter type is displayed. • The information is transmitted from the SB-910 to the camera. Fluorescent filter Incandescent filter How to attach SJ-3 color filters (optional) Attach the filter to Color Filter Holder SZ-2 (optional) as shown in the diagram. • Insert the filter edges into the slits on the holder, and then align the filter positioning hole with the holder pin. • Align the filter identification code (silver marks) with the black bar on the holder.
Flash Photography with Color Filters Place the filter holder on the flash head with the Nikon logo facing up, as shown in the diagram, and insert it into the slit at the top. • Be sure to attach the filter to the filter holder before placing the filter holder on the flash head. Check the LCD. • The filter type is displayed. • Be sure that nothing obstructs the filter detector.
v Notes on using SJ-3 color filters • These filters are consumable items. Replace them when they deteriorate or their colors fade. • The heat generated from the flash head can warp the filters. However, this will not affect their performance. • Scratches on the filters will have no effect on performance unless the filters fade in color. • To remove dust or dirt, wipe the filter lightly with a soft, clean cloth.
