Nikon D70S Manuel D’Utilisation

The following fl ash sync settings are available in P, S, A, and M modes:

This mode is recommended for most situations.  In P  and 
A  modes, shutter speed will au to mat i cal ly be set to values 
between 

1

/

60

 and 

1

/

500

 s.

Red-eye reduction lamp lights for approximately 1 s before 
main fl ash, causing pupils in subject’s eyes to contract and 
reducing “red-eye” effect sometimes caused by fl ash.  Ow-
ing to 1 s shutter-release delay, red-eye reduction is not 
recommended with moving subjects or in other situations 
in which quick shutter response is required.  Do not move 
camera while red-eye reduction lamp is lit.

In S and M modes, fl ash fi res just before shutter closes, creat-
ing effect of stream of light following moving subjects.  In P 
and A modes, slow-rear curtain sync is used to capture both 
subject and background.  Use of tripod is recommended to 
prevent blurring caused by camera shake.

Rear-curtain sync

Slow rear-curtain sync

Combines red-eye reduction with slow sync.  Available only 
in P and A modes.  Use of tripod is recommended to prevent 
blur ring caused by camera shake.

Slow sync with red-

eye reduction

Flash is combined with shutter speeds as slow as 30 s to 
cap ture both subject and background at night or under dim 
light.  Available only in P and A modes.  Use of tripod is rec-
ommended to prevent blur ring caused by camera shake.

Slow sync

Red-eye reduction

Front-curtain sync

The fl ash angle of the built-in Speedlight can cover the fi eld of view of an 18 mm lens.  
It may not be able to light the entire subject with some lenses or apertures (

 101).

When On is selected for Custom Setting 5 (ISO auto;   142), sensitivity will automati-
cally be adjusted as required for optimal fl ash output.  This may result in foreground 
subjects being underexposed in fl ash photographs taken at slow shutter speeds, in 
daylight, or against a bright background.  In these cases, choose a fl ash mode other 
than slow sync or select mode A or M and choose a larger aperture.
