Taking Daylight Synchro-Flash Photographs (Super FP Flash Mode) . [. . . ] This mode can be used for most of the subjects under normal conditions -- when shooting with the sun behind you, when the subject contrast is not too strong, and so forth.
17
TTL Direct Light Metering
Aperture-preferred automatic exposure allows you to take pictures by utilizing the lens depth of field effect (blurred background, for example). 95
Set the mode selector lever to the "AUTO" position.
18
Set the aperture.
Reference P. 117
Basic aperture settings;
Press the shutter release lightly to activate the viewfinder display.
The bar tip indicates the shutter speed.
19
Focus on your subject.
Press the shutter release to take the picture.
A built-in battery conserver turns off the viewfinder display after 120 sec.
20
If you see an overexposure warning signal ("OVER" blinks), set the aperture to a larger number.
If the shutter speed is too slow, set the aperture to smaller number to prevent camera shake.
21
Rewinding the Film
When the exposure counter indicates the end of your roll of film.
Push the "R" button.
22
Fold out the rewind crank and wind it until the film tension is released.
Open the camera back by pulling up on the
rewind knob and remove the film.
23
Taking Photographs (II) -- Automatic Exposure --
The spot metering system of the OM-4T enables you to control the exposure as you like. It insures perfect exposure of backlighted and high contrast subjects and expands shooting possibilities in the auto mode for more creative photography.
24
How to Use the Spot Measurement
Reference P. 96-100
Align
the
microprism
area with the area
you want to measure. (The spot metering range is outlined by the outer edge of the microprism. )
Spot metering range
25
Press the spot button to take meter reading.
You will hear an electronic sound and the word "SPOT" will appear in the viewfinder. The metered value is displayed by the mark.
If you shift the camera, another mark will indicate the exposure value in the center of the frame along with the spot metered value.
26
Press the shutter release to take the picture.
The subject will turn out correctly exposed,
regardless of the brightness of the background.
The spot metering mode will be automatically cleared after the shutter has tripped, or after 120 seconds have passed, and it will return to the, TTL direct light metering mode.
27
How to Clear the Spot Metering
With the lever at "CLEAR", the mode will return to TTL direct light metering.
"SPOT" and
mark disappear.
28
How to Use the "Multi-Spot Measurement" Mode
Reference
P. 101-104
Spot metering is possible in up to 8 spots.
This sample photo shows a backlighted subject.
29
Take spot metering on the face (first spot).
Take spot metering on the ship in the background (second spot).
30
Compose your picture and press the shutter release.
Both the subject and the background are correctly exposed.
To cancel the metered value, operate the clear lever.
31
Highlight Control
Reference P. 105-106
If you want to render white objects in white. . .
In ordinary shooting, white objects will turn
out grayish if the picture is taken in strong brightness over the entire frame. .
32
Take spot metering on the part of the subject
which you want to render in white.
Press the HI. LIGHT button.
Exposure will be automatically corrected to give 2-step overexposure.
33
Press the shutter release to take the picture.
The white object turns out white.
The highlight control is cleared by pressing the HI. To cancel the metered value, use the clear lever.
34
Shadow Control
Reference P. 107-108
If you want to render black objetcts in black. . .
In ordinary shooting, black objects will turn
out grayish if it is very dark over the entire picture
frame.
35
Take spot metering on the spot which you want to render in black.
Press the SHADOW button.
Exposure will be automatically corrected to give 2 2/3step underexposure.
36
Press the shutter release to take the picture.
The black object turns out black.
The shadow control is cleared by pressing the SHADOW button once again. To cancel the metered value, use the clear lever.
37
Taking Photographs (III) -- Automatic Exposure --
In automatic exposure, the same picture will be exposed with a very different exposure
value if it is taken in different backgrounds. It can be used in both the TTL direct metering and spot metering modes. Once an exposure value stored in memory, it does not vary even if you change the aperture (or shutter speed).
38
How to Use the Exposure Memory Lock System
Reference P. 109-110
The memory lock system is convenient for taking many pictures of the same subject in different backgrounds or costumes.
Operate the lever to set up the memory mode. The letters "MEMO" will appear in the viewfinder
and the memory signal will blink twice.
39
Frame the composition as you desire.
The Exposure Value is Stored in Memory after
Shooting.
40
The memory will keep on for 60 minutes after the shutter has tripped.
Change the composition and shoot.
The subject is exposed with the same exposure value even if you change the composition.
41
To clear the memory, use the clear lever.
The memory is also cleared in the following cases: 1. When the mode lever is switched.
42
Taking Photographs (IV) -- Manual Exposure --
The OM-4T permits manual exposure on center-weighted, averaged metering and spot metering. It allows you to choose the optimum aperture and shutter speed which suit your
subject and taste.
43
How to Take Pictures on Center-Weighted, Averaged Metering
Set the mode selector dial to the "MANUAL" position.
44
Set the bar graph tip to the fixed point between the arrows by adjusting the aperture and/or shutter speed rings.
Fixed point
The shutter speed you have set will be displayed in the viewfinder.
Shoot.
45
How to Use the Spot Measurement
Reference P. The mechanical shutter will operate to trip at 1 /60 sec.
You cannot use the motor drive, winders and flashes with the mechanical shutter.
59
Using the Viewfinder Illuminator
Push the button if the viewfinder display is too dark to read.
60
How to Turn Off the Beeper
To turn off the audible signal, push the lever to the right (in the direction of the arrow).
You will no longer hear PCV sounds when turning on the spot metering, highlight and shadow
controls, when operating the memory/clear lever, checking the batteries, or when mounting and
dismounting the lens.
