Nikon N4004s - Manual (Page 55)

Automatic Balanced Fill-Flash Photography
In program, aperture-priority or shutter-priority auto exposure
mode, when shooting a scene with a brightness of EV10 or
higher (at ISO 100) where the subject in the central area of the
triple sensor is darker than other areas by more than approx.
1.5EV, the ready-light LED blinks to tell you to use built-in TTL
flash or accessory Nikon speedlight for fill-in lighting.
For automatic balanced fill-flash photography, first set the
camera in program auto exposure mode so correct aperture
is automatically selected for the scene’s background, using a
synchronized camera shutter speed of 1/100 sec. The multi­
sensor meter of the N4004s measures contrast and brightness
for both subject and background, and automatically adjusts
speedlight output so you get good overall pictures without
complicated techniques.
Maximum shooting distance for balanced fill-flash
photography
Near a window Approx. 3 m
Normal outdoor shot Approx. 2 m
Scene containing the sun Approx. 1.5m •
• For scenes where the sun, a shining sea or a bright sky covers
a large part of the background, the camera automatically
selects smaller apertures, and because the power of the built-
in flash is limited, the results may be insufficient. If the ready-
light blinks after shooting, move closer to the main subject or
use an external speedlight with a larger guide number.
• With scenes where the background is extremely bright, the
ready-light may not blink after the shot, even if the flash is
insufficient for correct exposure.
