This mode is recommended for most situations. In pro-
grammed auto and aperture-priority auto modes, shutter
speed will au to mat i cal ly be set to values between

/
8,000 s with Auto FP High-Speed Sync).
Flash is combined with speeds as slow as 30 s to cap ture
both subject and background at night or under dim light.
This mode is only available in programmed auto and aper-
ture-priority auto ex po sure modes. Use of tripod is recom-
mended to prevent blur ring caused by camera shake.
In shutter-priority auto or manual exposure mode, fl ash fi res
just before the shutter closes, creating effect of a stream
of light behind moving objects. In programmed auto and
ap er ture-pri or i ty auto, slow rear-curtain sync is used to cap-
ture both sub ject and background. Use of tripod is rec om -
mend ed to pre vent blurring caused by camera shake.

28, 27, 26, and 25 Speedlights), red-eye reduction pre-fl ash
lights for approximately one second before main fl ash. Pu-
pils in subject’s eyes to contract, reducing “red-eye” effect
sometimes caused by fl ash.

only available with SB-series 800, 80DX, 28DX, 28, 27, 26,
