Switching Illumination Patterns
In fl ash photography, the center of the image is most illuminated, while the edges
are darker. The SB-910 provides three types of illumination patterns with different
light falloff at edges. Select the suitable pattern according to the photography
environment.
Standard
The basic illumination pattern for common
fl ash photography environments
Even The light falloff at the edge of the image
is less than with the standard illumination
pattern.
Suitable for group photographs, in which •
sufficient light is required without light
falloff at the edges.
Center-weighted The center-weighted pattern provides larger
guide numbers at the center of the image
than the standard illumination pattern (the
light falloff at the edge will be greater than
the standard illumination pattern).
Suitable for shots, such as portraits, in •
which the light falloff at the edge of an
image can be ignored.
