Nikon 1797 Digital Camera User Manual


 
Depth of field
The zone of sharpest focus in front of, behind, and around the
subject on which the lens is focused; can be previewed in the
F5 and some other Nikon cameras.
D-type AF Nikkor lenses
AF Nikkor lenses that send Distance Information to the F5’s
microcomputer. Used for 3D Color Matrix Metering or 3D Multi-
Sensor Balanced Fill-Flash (with Nikon SB-50DX/SB-28/
SB-28DX/SB-27/SB-26/SB-25 Speedlight).
DX code
Film information code printed on film cartridge. When the F5 is
set to its automatic film speed setting mode and DX-coded film
is loaded, it senses the film speed (ISO 25 to 5000).
EV
Exposure Value: A number representing the available combina-
tions of shutter speeds and apertures that give the same expo-
sure effect under conditions of similar scene brightness and
ISO.
At ISO 100, the combination of a one-second shutter speed
and an aperture of f/1.4 is defined as EV1.
The camera may be used only within the EV range of the expo-
sure meter. For example, with the F5, the exposure metering
range is from EV0 to EV20 for 3D Color Matrix Metering and
Center-Weighted Metering, at ISO 100 with an f/1.4 lens.
Exposure bracketing
Shooting the same subject at a range of different exposures.
The F5 camera provides Auto Exposure Bracketing/Flash
Exposure Bracketing.
Auto Exposure Bracketing: Auto Exposure Bracketing
performs automatic exposure bracketing with varied shutter
speed and/or aperture.
Flash Exposure Bracketing: Enables a photographer to
automatically bracket exposures at varied flash output levels,
in TTL auto flash shooting, without changing the shutter
speed and/or aperture.
