Selecting suitable illumination pattern The SB-900 provides three illumination patterns with differing light falloff at image edges. Select a pattern suitable to your shooting environment. • To change illumination pattern, refer to “Switching illumination pattern” in the SB-900 user’s manual. Standard illumination Optimized for digital photography and suitable for various shooting conditions Illumination is set to standard as the default. Standard illumination has been designed to provide light distribution that matches the image area of digital cameras. This means that light falloff at the edges of the image is less than with conventional external flash units. Standard illumination is appropriate for typical flash shooting environments. Equipment used Camera: D3 / Lens: AF-S NIKKOR 24-70mm f/2.8G ED / Speedlight: SB-900 Center-weighted illumination Suitable for portraits and other such shots in which light falloff at image edges can be ignored Center-weighted illumination provides larger guide numbers at the center of the image than other illumination patterns at the same focal length (the light falloff at the edges will be greater than with other illumination patterns). Suitable for portraits and other such shots in which the light falloff at the edges of the image can be ignored, or backlit shots in which flash lighting with larger guide numbers is effective. Equipment used Camera: D3 / Lens: AF-S NIKKOR 24-70mm f/2.8G ED / Speedlight: SB-900 Even illumination Suitable for shooting indoor group photographs with bright image edges The light falloff at the edges of the image is less than with standard illumination. Suitable for shooting indoor group photographs in which sufficient light is required without light falloff at the edges. Equipment used Camera: D3 / Lens: AF-S NIKKOR 24-70mm f/2.8G ED / Speedlight: SB-900 Bounce flash Bounce flash Provides more natural-looking pictures Bounce flash Bounce flash Provides more natural-looking pictures When photographing a subject standing in front of a wall, tilt or rotate the flash head up to bounce light off the ceiling. This softens the light falling on the subject and eliminates the shadow behind and below the subject. By using a Nikon Diffusion Dome, you can achieve a greater bounce flash effect. • To take bounce flash photographs, refer to “Bounce flash operation” in the SB-900 user’s manual. • To soften the shadows behind a subject, tilt the flash head up 90° and bounce the flash off the ceiling. • This diffuses and softens the flash light to give subtle face and skin tones. • When bounce flash is not used, the subject’s face is rendered shiny and strong shadows appear behind. Equipment used Camera: D3 Lens: AF-S NIKKOR 24-70mm f/2.8G ED Speedlight: SB-900 with softer shadows Normal flash Reference Tilting the flash head and choosing a refl ecting surface • The more the flash head is tilted upward, the more the flash light is softened. • Rotate the flash head horizontally to achieve the same effect when holding the camera in the vertical position. • The effective shooting distance between the flash head and the reflecting surface is approx. 1 m (3.3 ft.) to 2 m (6.6 ft.) depending on shooting conditions. • With color photography, select white or highly reflective surfaces to bounce the light off. Otherwise, pictures will come out with an unnatural color cast similar to that of the reflecting surface. 90. Compensate the brightness and color shading of the subject Flash head tilts up 90° • Compare the effects of bounce flash with the flash head tilted up 90°, 75° and 105°. • The larger the tilt angle of the flash head, the wider the flash light is spread and more evenly the subject is illuminated. However, image brightness is reduced. • When the flash is bounced off a wall or ceiling behind the camera, the flash light is more evenly spread, providing weaker shadow and more natural-looking photographs, although image brightness is reduced. • To achieve the desired bounce flash effect, adjust the tilt angle of the flash head, checking the results as you shoot. When shooting with short focal lengths, use a larger tilt angle, and when shooting with long focal length, use a smaller tilt angle.
