GENERAL FUNCTIONS
This chapter explains the various modes of the N90 camera’s
operation. Please review it thoroughly.
27
FILM ADVANCE MODE
There are three automatic film advance modes. To choose a
mode, press and hoid the fiim advance mode button and rotate
the command dial. Set ID for single-frame shooting, 3!il for
continuous low-speed shooting or Q!i” for continuous high
speed shooting, and so on.
28
SINGLE-FRAME SHOOTING
With the film advance mode at El, fully depressing the shutter
release button takes one picture and automatically advances
the film by one frame. Film is advanced immediately after the

release button or keep the button depressed. To take the next
shot, lift your finger from the button, then fully depress it again.
CONTINUOUS SHOOTING
Shots are taken continuously as long as you keep the shutter
release button fully depressed. You have a choice of shooting
speeds: approx. 3.6 fps (frames per second) in the ai” mode,
and approx. 2.0 fps in the
type batteries at normal temperature and at shutter speeds
higher than 1/250 sec. in the Manual exposure and Manual
focus modes. With shutter speeds slower than 1/250 sec., the
framing rate becomes progressively slower in proportion to the
shutter speed in use. If Focus Tracking is on, the maximum
shooting speed is approx. 3.0 frames per second in the Q|i“
mode.

29
EXPOSURE METERING SYSTEM
The Nikon N90 has three type of exposure metering systemsCenter-Weighted Metering and Spot Metering,
MATRIX METERING
This system is ideal for quick operation in any exposure mode
(pp. 49-66). With D-type AF Nikkor lenses including AF-I Nikkor,
3D Matrix Metering is automatically activated. 3D Matrix
Metering uses three types of data: (1) scene brightness, (2)
scene contrast and (3) focused subject's distance (Distance
Information). Data on scene brightness and contrast are
detected by the camera’s 8-segment Advanced Matrix Sensor,
while data on the focused subject’s distance is detected and
relayed by the D-type AF Nikkor lens in use. in addition, the
information sent by the camera’s autofocus system indicating
whether the main subject is centered is also considered in the
computation. By analyzing these data, the N90’s built-in
microcomputer is able to provide correct exposure even in
extremely complex lighting situations.
30
Matrix Metering,
If a non-D-type lens is used, Advanced Matrix Metering is
performed, Although lens' Distance Information is not given, 8segment Matrix sensor provides the correct exposure in most
lighting situations.
Note that Matrix Metering system can be used only with lenses
that have a built-in CPU (such as AF Nikkor and Al-P lenses.)
CENTER-WEIGHTED METERING
With 75% of the meter's sensitivity concentrated on the 12mmdia. circle in the viewfinder and 25% outside this circle, this
meter becomes useful in situations where you want to base
exposure on a specific area in the scene. In the auto exposure
mode, to measure the brightness of the picture’s off-center
portion, use the camera’s AE-L iever (pp. 88-89).
SPOT METERING
Nearly 100% of the meter’s sensitivity is concentrated on the
3mm circle in the center of the viewfinder. Use this meter for
reaiiy selective exposure control—achieving the best results
requires experience.
31
SETTING METERING SYSTEM
While pressing the metering system (K)button, rotate
command dial until the desired symbol—lO for Matrix Metering,
[»] for Center-Weighted Metering or ED for Spot Metering—
appears in the LCD panel.
If you are using a lens without CPU, or accessories such as bellows or
extension rings
8-segment Matrix Metering automatically switches off and Center-Weighted Metering switches on
while the (□) symbol blinks. (If Auto Multi-Program or Shutter-Priority Auto is set on the camera,
the exposure mode also switches automatically to Aperture-Priority Auto with f - - and blinking
exposure mode indicator.) In this case, use Center-Weighted Metering or Spot Metering.

Spot-Area Autofocus

The Wide-Area focus brackets delineate the focus detecting
area in the viewfinder. Subjects of sufficient brightness and
detaii can be detected within these brackets. In addition to
general photography, autofocus using Wide-Area focus
brackets is suited to action photography in which the moving
subject requires a wide-range focus detection area.
However, focus detection may not be possible if the subject is
too small to fully cover the Wide-Area focus brackets. If various
subjects, each at a different distance, fall within the focus
detection area, focus will be confirmed for a single subject as
follows:
•For subjects of equal brightness: the closer one will be
focused.
•For subjects of unequal brightness: the brighter one will be
focused.
Spot Area AF, in which the focus detecting area is shown by
the 3mm-dia. circle at the center of the viewfinder, is
recommended in the following situations:
a. Subject considerably
smaller than the Wide-Area
focus brackets*
b. Subject obscured by an
object, such as a fence, in
the foreground
. A particular portion of the
subject must be in focus,
such as the eyes in a
portrait
* Use focus lock. See ’AUTOFOCUS WITH MAIN SUBJECT OFF CENTER" on pages 40 to 43.
•* To give correct exposure on your subject, see ‘AE-L LEVER" on pages 88 to 89 or "TO OBTAIN METER READING FOR A
PARTICULAR SUBJECT IN MANUAL EXPOSURE MODE" on pages 90 to 91.

d. Strongly backlit subject,
such as someone standing
beside bright window**
AUTOFOCUS
The Nikon N90 has two autofocus modes, Single Servo AF with
Focus-Priority and Continuous Servo AF with Release-Priority.
In either autofocus mode and in any film advance mode, Focus
Tracking automatically activates when the subject starts
moving. Focus Tracking enables the camera to analyze the
speed of the moving subject according to the focus data
detected, and to obtain correct focus by anticipating the
subject’s position—and driving the lens to that position—at the
exact moment of exposure. You can thus obtain correctly
focused pictures for many moving subjects.
Data Link System users
You can give Focus-Priority to Continuous Servo AF
and/or Release-Priority to Single Servo AF.
For Single Servo AF in continuous shooting, you can also
cancel focus detection and lens driving for the next shot
after the first shot is taken so that the subject focus
remains locked.
For details, see the Nikon AC-1 E card's instruction
manual.
Caution
Do not attempt to turn the lens focusing ring or impede its
rotation when the focus mode selector is set to S or C.
In addition to AF Nikkor lenses (including D-type AF
Nikkor and AF-I Nikkor lenses except the AF Nikkor lenses
for F3AF), autofocus is possible with AF Teleconverter TC-
16A attached to non-AF Al-Nikkor lenses with a maximum
aperture of f/3.5 or brighter. Al-Nikkor lenses that cannot
be used with the TC-16A are:

Autofocus operation depends on general lighting, subject contrast and detail, and
other technical factors. In rare situations where autofocus (and manual focus with
Electronic Rangefinder) is not possible, ► i blinks telling you to focus manually with
clear matte field (p. 48) or perform autofocus on another subject located at same
distance.
A. Very dark subject
Focus manually with clear matte field, or
for autofocus, focus on another brighter
subject located at same distance, then
use focus lock (pp. 38-43). Or, use a
Nikon autofocus Speedlight to perform
autofocus with Speedlight's AF
illuminator.
44
B. Low contrast subject
Focus manually with clear matte field, or
for autofocus, focus on another subject
at same distance but with more contrast,
then use focus lock (pp. 38-43).
C. Strongly backlit subject or bright
subject with shiny surface such as
silver or aluminum, or scene in which
there is a pronounced difference in
brightness, such as the light
patterns created by blinds.
Focus manually with clear matte field.
In the following situations, ignore in-focus indicator • or
• Scene with subject located at different distances. (For
example, when shooting a person over a fence or when
shooting animals inside a cage)
Use Spot Area for autofocus (page 34) or focus manually with
clear matte field.
• With an extremely bright object near your subject
Use Spot Area for autofocus (page 34) or focus manually with
clear matte field.
• When using a linear polarizing filter*, or other special filter
such as a soft-focus filter.
Focus manually with clear matte fieid.

MANUAL FOCUS
‘^5 f5.
To focus manually, set the focus mode selector to M. (If the lens
has an A-M switch, set it to M. If you are using an AF-I Nikkor
iens, set the focus mode ring to M or M/A.)
There are two ways of assuring precise manual focus: with the
Electronic Rangefinder or with the viewfinder’s clear matte field.
46
Manual focus with Electronic Rangefinder
The Electronic Rangefinder enables you to see focus status
with the viewfinder indications while you are manually focusing.
It works with most Nikon lenses (including AF Nikkor when
operated manually) which have a maximum aperture of f/5.6 or
faster. (For a complete list of usable lenses, see LENS
COMPATIBILITY CHART on p. 104).
1. Look through viewfinder and position focus brackets on main
subject. Then lightly press shutter release button.
2. Keeping shutter release button lightly pressed, rotate lens
focusing ring in direction indicated by focus-to-left arrow (4)
3. Confirm in-focus indicator • appears, then fully depress

or focus-to-right arrow (►), until arrow disappears and in
focus indicator • appears.
If focus-to-left arrow {^ does not disappear when you turn
focus ring counterclockwise to the limit, subject is closer
than the distance at which the lens is able to focus. Move

EXPOSURE MODE
Light reaching the film is controlled by shutter speed and lens
aperture. The proper combination results in a correct exposure.
Shutter speed and lens aperture settings are based on the ISO
speed set for the film in use and the operation of the camera's
exposure control system.
The relationship between aperture and shutter speed is as
the amount of light transmitted. For example, a shutter speed
of 1/500 sec, passes half the light of 1/250 and double the light
of 1/1000 sec. The aperture f/8 passes half the light of f/5.6
and double the light of f/11, If the correct exposure for a scene
is 1/500 at f/8, then we can also select 1/250 at f/11 or 1/1000
at f/5,6 and achieve the same exposure results, and so on.

SELECTING EXPOSURE MODE
Selecting the exposure control mode means deciding if you
want the shutter speed and/or lens aperture to be set
automatically or manually.
The Nikon N90 camera offers two types of programmed auto
exposure modes, Auto Multi-Program (P) and Vari-Program (Ps),
as well as Shutter-Priority Auto (S), Aperture-Priority Auto (fl),
and Manual (f1) exposure modes.
50
Programmed auto exposure modes (P/Ps)
With the N90’s microcomputer choosing the combination of
shutter speed and aperture automaticaiiy, you can concentrate
on picture composition, without worrying about exposure.
Note that programmed auto exposure modes operate only with Nikon tenses
that have a built-in CPU (AF Nikkor and Al-P NIkkor lenses).
When Ps for Vari-Program is selected, you have a choice of
seven options: (1) Portrait Program, (2) Portrait Program with
Red-Eye Reduction, (3) Hyperfocal Program, (4) Landscape
Program, (5) Silhouette Program, (6) Sport Program and (7)
Close-Up Program,
For details about Vari-Program, see pp. 67-85.
Auto Multi-Program (P) is used for most common picture-taking
situations. The chart at right shows the shutter speed/aperture
combinations for Auto Multi-Program that are selected at each
EV (exposure value) brightness level.
With Auto Multi-Program, you can use the Flexible Program
function to temporarily shift an automatically selected shutter
speed/ aperture combination and obtain the desired shutter
speed/aperture (p. 55).
Program chart of Auto Multi-Program
To check shutter speed and aperture values, follow either the
black or red line to where it intersects the diagonal line.

With AF Zoom 28-70mm f/3.5-f/4.5 at 70mm setting
51
Shutter-Priority Auto exposure mode
You manually set the shutter speed you want. To freeze the
action, use a high shutter speed; to create motion effects,
choose a siower shutter speed. The N90's microcomputer
automatically sets the proper aperture to match the manually
selected shutter speed for correct exposure. See pp. 56-59 for
Shutter-Priority Auto operation.
Note that Shutter-Priority Auto exposure mode operates only
with Nikon lenses that have a built-in CPU (AFNikkor and Al-P
Nikkor lenses).
Aperture-Priority Auto exposure mode
You can control depth of field by varying the aperture. Smaller
apertures make the background and foreground sharper
(recommended for landscape pictures) while larger apertures
tend to blur the background (recommended for portraits).
Your selected aperture will determine the shutter speed that is
automatically set by the camera’s microcomputer. When using
smaller apertures with correspondingly slower shutter speeds,
remember that, generally, any speed below 1/(focal length in
use) second, requires the use of a tripod to prevent picture blur
due to camera shake. The higher the corresponding shutter
speed to the aperture you set, the easier it is to stop action.
Adjust the selected aperture if the speed is not appropriate for
conditions or the specific effect you want.
For Aperture-Priority Auto operation, see pp. 60-62.
52
Manual exposure mode
Manual exposure control allows you to make both aperture and
shutter speed settings. For a technically correct exposure,
follow the recommendation of the camera’s light meter, as
indicated by LCD readout. To achieve a specific creative effect
(e.g., intentional blur, intentional under- or over-exposure),
disregard the LCD and modify the recommended exposure
settings.
For Manual exposure operation, see pp. 63-66.
