Sensitivity ( ISO Equivalency)
“Sensitivity” is a measure of how quickly the camera
responds to light. Your Nikon digital camera normally
has a sensitivity roughly equivalent to fi lm with an ISO
50 rating. When lighting is poor and the fl ash is off
(
), the camera will automatically increase sensitivity,
permitting faster exposures and minimizing blur caused
by inadvertent camera movement (camera shake). An
ISO icon will appear in the monitor to warn that the
picture may be slightly mottled.
The (Camera Shake) Icon
When lighting is poor and the fl ash is off ( ), shutter
speeds will slow and pictures may be blurred. If the
shutter speed required for exposure is very slow, a
(camera shake) warning will appear in the monitor. Use
of a tripod or support is recommended.
Flash Range
Flash range varies with zoom position. When the camera is zoomed all the way out,
the fl ash has a range of 0.4 – 3.0 m (1´4˝ – 9´10˝). The range at maximum zoom is
0.4 – 1.7 m (1´4˝ – 5´7˝).
Close-Ups
The fl ash may not be able to light the entire subject at distances of less than 40 cm
(1´4˝). When taking close-ups, play each picture back after shooting to check the
results.
Flash Mode Selection
Depending on the mode selected, the fl ash mode may change automatically when
you choose a new shooting mode (
30–37, 51). In (manual) mode, the camera
“remembers” the current fl ash mode setting even when the camera is turned off. The
most recent setting will automatically be restored whenever the mode dial is set to
, unless the Reset all option in the setup menu is used to restore default settings
( 80). In (auto) mode, the camera only stores the fl ash mode if the fl ash fi res
at a setting of (auto with red-eye reduction). If AUTO is not selected before the
camera is turned off, the fl ash will be set to the next time the camera is turned
on. Otherwise the fl ash mode will automatically be set to AUTO.
