Nikon SB-27 instruction manual Bounce flash operation, Catchlight, Center-Weighted/Spot Fill-Flash

Bounce flash operation

Bounce the light off the ceiling or walls to illuminate the subject indirectly, softening shadows and producing more natural portraits. The SB-27 comes with a built-in wide flash adapter for this purpose.

(Applicable to all camera groups)

Catchlight

By using the SB-27’s built-in diffuser and bouncing the light off the ceiling, you can create a “catchlight” which softens harsh shadows caused by bounced light, resulting in more natural portraits.

(Applicable to all camera groups)

Center-Weighted/Spot Fill-Flash

This mode operates with Center-Weighted or Spot metering. These metering systems measure the background brightness and control the flash, providing less light than with Matrix Balanced Fill-Flash.

Recommended with non-AF Nikkor lenses in place of Matrix Balance Fill-Flash, which cannot be used.

(Applicable to F5, F4-Series, F100, F90X/N90s, F90-Series/N90, F70-Series/N70, F60-Series/N60, F50-Series/N50, F-801s/N8008s, F-801/N8008, F-601/N6006, F-601M/ N6000, F-401x/ N5005)

Flash exposure compensation

In combination with on-camera exposure compensation, you can manually adjust the amount of flash output when using a Speedlight in AUTO flash mode. To achieve correct exposure with a large white background, a small subject in the center of the viewfinder, or a subject close to the edge of the frame, underexpose; overexpose if your subject is positioned against an “infinity” background.

(Applicable to all camera groups except group VII)

Flash shooting distance range

Your subject must be within acceptable flash shooting distance range in order to receive sufficient illumination from the flash. This range varies depending on the aperture and ISO film speed. In flash operation, make sure that the subject is within flash shooting distance range.

(Applicable to all camera groups)
