Taking pictures on automatic and manual with
Exposure Modes settings

Exposure Modes:
1. Mode dial -
The Mode dial selects the exposure modes and Digital-Variprograms of
the camera.
Exposure modes
-
P Auto Multi
Program - lets the camera optimize exposure to suit the subject.
Allows you to set shutter speed and aperture or adjust exposure with
exposure compensation controls.
S Shutter
Priority Auto - allows you to choose shutter speeds to suit the
subject you are shooting, fast shutter speeds for sports and action and
slow shutter speeds to blur moving objects or photograph in low light
situations.
A Aperture
Priority Auto - allows you to set the aperture for control of
depth of field, either to bring more things into focus or to throw a
background out of focus.
M Manual
- allows you to set both shutter speeds and aperture manually for full
control of exposures.
2. Bracket
button - In P, S, A, and M modes the camera offers three
bracketing options. Bracketing is not available in Digital Vari-Program
modes.
Bracketing function is turned on and off by holding down the Bracketing
button and rotating the Main command dial.
CSM 12 - Sets the three bracketing
options.
AE & Flash
or AE only - With each shot the camera varies the exposure by
±2EV, bracketing exposure is selected with exposure compensation
(modes P,S, and A) or by user (mode M). Each shutter release produces
only one exposure, so you must release the shutter three times to get a
three shot bracketing set.
AE & Flash
or Flash only - With each shot the camera varies the flash level
by ±2EV. Each shutter release produces
only one exposure, so you must release the shutter three times to get a
three shot bracketing set. Available only in iTTL and auto aperture
flash control modes.
White Balance
- White balance bracketing only requires one exposure to make three
separate white balance setting files. Not available with NEF (RAW)
because NEF (RAW) files contain entire range of white balance setting
information.

Exposure Metering Modes
|
3D
color matrix/Color
matrix metering - Metering is performed by a 1,005-pixel RGB
sensor, which sets exposure based on a variety of information from all
areas of the frame. This method is particularly effective when the
frame is dominated by bright (white or yellow) or dark (black or dark
green) colors, when its results approach what is seen by human eyes.
3D color matrix metering, which uses range information from the lens in
adjusting exposure, is available only with type G or D lenses. Color
matrix metering, which does not include range information, is available
with other CPU lenses.
Matrix metering will not produce desired results with autoexposure lock
or exposure compensation, but is recommended in most other cases.
|
Center
weighted metering
- Camera meters the entire frame but assigns greatest weight to area in
center of frame 8mm (0.31") in diameter, shown by the corresponding
8-mm reference circle in the viewfinder. Classic meter selection for
portraits; recommended when using filters with an exposure (filter)
factor over 1x.
CSM
11 - this option controls the size of the area assigned the
greatest weight in center-weighted metering.
|
Spot
metering -
Camera meters a circle 2.3mm (0.09") in diameter (approximately 1% of
the frame). The circle is centered on the current focus area, making it
possible to meter off-center subjects (if Closest subject for AF-area
mode is selected, the camera will meter the center of the focus area).
Ensures that the subject will be ciorrectly exposed, even when the
background is much brighter or darker.
|
3. Metering
mode button - (left button)
Press this button and rotate the main command dial (top back right of camera - under your right thumb) to
access the three metering modes. 3D color matrix/Color matrix metering,
Center weighted metering and Spot metering. The metering mode options
are available in P, S, A, and M camera operation modes.
4. Exposure
compensation button - (right
button)
Press this button and rotate the main command dial to change exposure
compensation in increments of 1/2 or 1/3 EV between -5EV
(underexposure) and +5EV (overexposure).
CSM 9 -
allows you to change the exposure compensation increments
between 1/2 and 1/3 EV.
Exposure compensation is available for camera modes P,S and A. In mode
M the electronic analog exposure display will indicate the selected exposure compensation but
not set the compensation.
