6. SETTING THE APERTURE
![]() |
The lens opening determines the amount of light entering the lens and exposing the film. The smaller the f-stop (f/2.0, f/2.8, etc.) the wider he lens opening and the greater the amount of light entering the lens. The larger the f-stop (f/16, f/11, etc.) the smaller the lens opening and the smaller the amount of light entering the lens. As the lens opening is moved from f/16 to f/11, the amount of light entering he lens is doubled. As the lens opening is moved from f/2.0 to f/2.8 he amount of entering light is cut in half. Rotate f-stop ring until the desired f-stop is opposite the aperture index line. Click stops are provided to prevent accidental movement from the setting made. If necessary, you may set f-stop ring between two f-stops. |
7. THE
CORRECT EXPOSURE
Your KS 1000 has a built-in
through-the-lens full aperture CdS exposure meter which measures the light
coming through the lens and enables you to set the proper exposure for a given
lighting condition. The correct exposure is obtained by setting the shutter
speed and f-stop (aperture) in the correct combination for the film, subject
and lighting conditions.
Set the desired
shutter speed opposite shutter speed index line by rotating shutter speed dial
(Read "SELECTING THE SHUTTER SPEED"). Shutter speed indicator in the
viewfinder indicates the shutter speed you just set.
Move film advance lever to
"ON" position.
Hold your camera, look at your subject through the view eyepiece and
check exposure meter needle.
Rotate f-stop (lens opening) ring and align exposure
meter needle with shutter speed indicator. F-stop is visible through aperture
readout window. If exposure meter needle goes above shutter speed indicator,
this means "overexposure"; select a faster shutter speed or a smaller
lens opening. On the contrary, if the needle goes below shutter speed
indicator, this means "under-exposure"; choose a slower shutter or a
larger lens opening.
If you want
to use a specific f-stop for depth of field control, you may set the f-stop
first and then the shutter speed, while other procedures are the same as above.
How your subject turns out in the picture depends on the f-stop setting (Refer
to "DEPTH OF FIELD"). The chart shows the exposure value range
(shutter speed and f-stop combinations) of your camera's metering system for
selected film speeds.
Exposure Compensation:
Though you learned how correct exposure is obtained,
in unusual lighting conditions, the desired effect or the correct exposure will
not be obtained in the final picture and exposure compensation is necessary.
Back-lit Subjects (when the light is
behind the subjects):
1. Move close to the subject for
meter reading, then, move back, focus and shoot.
2. If it is
impossible to approach the subject, adjust either shutter speed or lens opening
to overexposure. When you adjust the lens opening, open up the aperture by 1 or
2 stops.
Spot-lighted Subjects and Dark Backgrounds:
1. Move close to the subject for
meter reading, then move back, focus and shoot.
2. If it is
impossible to approach the subject, adjust either shutter speed or lens opening
to underexposure. When you adjust the lens opening, close down the aperture by
1 or 2 stops.
Tips for Better Results:
·
When
the shutter speed dial is set at "B" (Bulb), se the desired f-stop
and expose manually because metering with the built-in exposure meter is not
possible.
·
Do not
make an exposure setting by pressing depth of field preview button or turning
battery check ring because these will incorrectly influence the meter's reading
·
Outside
of the meter's coupling range, the exposure meter will not respond correctly.
For example, coupling range for ASA 100 film is from 1/4 sec. at f/1.4 to 1/1000
sec.
at f/16 (EV3 - 18). If the light is too dim, use supplementary lighting.
8. VIEWING AND FOCUSING
![]() |
![]() |
Since you are viewing through the lens, there is no parallax problem... what you are viewing in the viewfinder is exactly what will appear in the final photograph. This enables you to determine the exact composition of your subjects before pressing shutter release button. Even when you shoot close-ups, these is no danger of accidentally cutting off a portion of your picture |
. To assure the sharpest
possible pictures, your KS 1000 has a three way focusing screen with diagonal
split-image spot, microprism-image band and fresnel field... select according
to your subject.
Look into viewfinder eyepiece to
compose your picture.
Split-image focusing is helpful for the subject with
either vertical or horizontal lines. Rotate focusing ring until the split image
in split-image spot forms a single image. When it is out of focus, your
subject is split in two parts.
Microprism focusing is good for the subject which lacks
clear vertical or horizontal lines. Rotate focusing ring until the image in
microprism-image band appears sharp.
You can also focus with any part of
the area surrounding microprism-image band. This is most useful when taking
pictures with ultra telephoto lenses or in close-up photography with bellows
unit, macro lenses or extension rings because the other focusing aids may
darken appreciably.
9. DEPTH OF FIELD
When you focus on a specific subject, an area in front
of and behind the subject will appear acceptably sharp in your picture. This
area of acceptable sharpness is called "Depth of Field". The depth of
field is determined by the f-stop you select and the distance from the in-focus
subject to the film plane. As you get closer to your subject, or as you open
your lens (for example, from f/16 to f/2.8(, the depth of field becomes shallower.
By stopping the lens down (for example, from f/2.8 to f/16(, the depth of field
becomes deeper. Knowing how to use depth-of-field allows the photographer to
use the principles of "selective focus" to eliminate unwanted
foreground and background objects from his photographs, and could mean the
difference between a snapshot and a successful photograph. The depth of field
can be pre-determined in the following ways:
Depth of Field Preview Button:
|
Pressing depth of field preview button will set the lens at the corresponding opening you previously set on f-stop ring. This will enable you to preview the area of acceptable sharpness in the picture you take. The viewfinder will become dark corresponding to the f-stop you previously set on f-stop ring. Depth of field preview button will automatically return to its original position when you release it and the viewfinder will become as bright as before. |
Depth of Field Scale:
![]() |
After you have set the lens opening
and have focused the camera, the area of acceptable sharpness in front of and
behind your subject can also be determined on depth of field scale. Locate on
depth of field scale the two numbers corresponding to the f-stop you have set
on fstop ring.
The distance between these two f-stops on distance scale will be an area of acceptable sharpness in your picture. For example, if your lens is focused at 3 meters (10 ft.) and you shoot at 8 (f/8), the area of acceptable sharpness will be from 2.2 m (7.3 ft.) to 5 m (16.5 ft), by reading distance scale opposite both sides of the number "8" on the depth of field scale. |
Tips for Better Results:
* Do not depress the shutter release button when
depressing depth of field preview button.
10. INFRARED PHOTOGRAPHY
![]() |
For infrared photography using infrared films, a correction of distance scale is necessary because infrared light waves focus on a plane slightly behind that of visible light. When using infrared film you can compensate for this difference by focusing slightly behind your subject. |
First focus normally on
your subject and note the camera-to-subject distance opposite the distance
index line on distance scale. Turn focusing ring until this camera-to-subject
distance setting is opposite the infrared index line. For example, if distance
scale reads 5 m (16.5 ft) after focusing, merely shift the "5" (16)
scale to the "•" (red) position.
Tips for Better Results:
* Infrared radiation varies with the
degree of infrared light rays in the atmosphere.
* For exposure, follow the instruction sheets which are packed with the film.
11. HOLDING THE CAMERA
Support the camera in the palm of the
left hand, with the thumb and forefinger gripping the focusing ring.
The palm of the right hand should fit
against the right side of the camera body with the forefinger resting near the
shutter release button and the thumb on the camera back.
Look through the viewfinder with the
camera resting against the forehead to help steady it, and the left elbow held
in against the body.
As a general rule, the camera should
not be hand held at shutter speeds slower than 1/60 second. This becomes
particularly important when using lenses of longer than normal focal length,
where it may be necessary to use even faster speeds to eliminate camera movement.
At speeds slower than 1/60, a tripod is a must for the sharpest photographs.
IMPORTANT: When attaching the camera to a tripod
that has a long attachment screw, adjust the screw to less than 1/4 inch to
prevent damage to the interior of the camera body.
12. CHANGING LENSES - This is a standard K-mount lens
![]() |
![]() |
To mount the lens on the camera: To remove the lens from the camera: Grasp the lens firmly around the lens barrel in one hand. With the other hand, hold the camera body and press lens release lever and turn the lens counterclockwise until it stops. The lens now can be removed. |
You can also change lenses easily
without looking, even in the dark, by means of lens locator node. Line up lens locator
node with lens release lever and turn the lens clockwise for mounting the
lens. For removing the lens, press lens release lever and turn the lens
counterclockwise until lens locator node and lens release lever line up.
Tips for Better` Results:
·
Whenever
a lens is mounted on the camera, make sure that the lens is perfectly
mounted.
·
Do not
touch any of the internal parts or permit dust or dirt to enter the camera
body when removing or attaching lenses.
·
Protect
the inside of the camera by putting on the body cap whenever the camera is
carried or kept with the lens removed.
NOTE: A wide range of Sears interchangeable
lenses including extremely wide angle lenses, telephoto lenses and zoom lenses
are available to enable you to expand the pleasure of your picture-taking.
Since the camera is designed to accept any lens with the "K" type
bayonet mount, your KS 1000 affords you the opportunity to select any
interchangeable lens or accessory of the "K" type bayonet mount
available on the market.
13. USING SELF-TIMER
|
|
Your KS 1000 has a built-in self-timer which delays the shutter release a maximum of 10 seconds. This enables you to include yourself in your own pictures and is also of benefit in taking close-ups or photomicrographs where camera movement must be avoided. |
First,
advance film advance lever. Then move self-timer lever counterclockwise.
According to the degree you have moved it, you can adjust the operating time.
For the maximum delay, move it until it stops. Press shutter release button to
start the self-timer moving.
Tips for Better Results:
·
You can
set self-timer lever first, if you wish, and then advance film advance lever.
·
The
camera should be placed on a tripod or other sturdy support when using
self-timer.
·
When
using a tripod with a long thread length (more than 5.7 mm), be careful not to
forcibly screw in the thread further than the depth of the socket.
·
Turn
the self-timer lever to the original position with your finger to disengage the
self-timer setting.
14. USING AUTO WINDER
The Sears KS Autowinder can be used
with the KS-1000 and KS Auto cameras. By operating the shutter release button
on, the winder, it can be used for rapid sequence photography at approximate
2 frames per second (at shutter speed 1/125 sec.). By first setting the
selection switch you may choose frame-by-frame shots or rapid sequence shots
according to your needs. You can for instance capture the rapid movement in
sports, or the fleeting facial expressions that make your picture-taking a
more enjoyable experience
15. UNLOADING FILM
|
After the last picture on the roll of
film has been taken, rewind the film and unload your camera as follows: Press film rewind release button. Lift up
film rewind crank and turn it clockwise until film rewind release button stops
revolving and you feel the film tension released. This indicates that the film
has been completely rewound into the cartridge. Open back cover by pulling up film rewind knob. |
Remove the film cartridge and have
the film processed as soon as possible.
Tips for Better Result:
·
Always
unload your camera in the shade or in a poorly-lit place, never in direct
sunlight or other bright light.
·
When
you reach the end of the roll of film, film advance lever will tighten and
refuse to advance. If this happens, do not advance film advance lever by force
for "just one more shot", otherwise the film will be torn out of the
cartridge.
·
Film
rewind release button will remain in place once it is pressed, and return
automatically to its original position when film advance lever is advanced.
16.
MULTIPLE EXPOSURES
![]() |
![]() |
Your KS 1000 has a multi-exposure
device which allows you to make double exposures for special effect and lots of
creative fun. Make the first picture in the normal way. Release the lock by sliding the multi-exposure Lock Lever to the left until the red dot appears. For the second exposure, advance film advance lever while pressing multi-exposure button firmly with the other hand. This will set the shutter for the second exposure without advancing the film and exposure counter. |
![]() |
When multi-exposure shots are not required, be sure to lock the multi-exposure Button by sliding the Multi-exposure Lock Lever towards the right until the red dot disappears. |
![]() |
Tips for Better Results: ·
Good
results in multi-exposure depend on careful shutter speed and lens opening
setting. This means, in order to prevent overexposure of the final picture, we
suggest that the first picture should be underexposed by adjusting either
shutter speed or lens opening. ·
If you
want, repeat the same action for the third exposure or more. · Whenever advancing the film advance lever for second exposure, make sure that the multi-exposure button is pressed firmly with the other hand and watch to see that exposure counter is not advanced, indicating that multi-exposure picture is ready to be taken.

17. FLASH PHOTOGRAPHY
You can use a flash at night or in a
dimly lit room as well as for supplementary lighting in outdoor photography.
The camera and electronic flash will be fully synchronized with the shutter
speed at "B" and 1 sec. to 1/125 sec.
Cordless electronic flash unit:
If you are using an electronic flash
unit with a built-in hot shoe contact, it can be attached directly to hot shoe
on top of the camera pentaprism.
Exposure for flash
photography:
The exposure is determined by the
guide number of the flash bulb or electronic flash unit. The guide number
represents a relationship between the light output of the flash and the speed
of the film. Guide numbers for flash bulbs can be found on the package and
guide numbers for electronic flash units are found in the technical
specifications. Using the guide number, you can determine the correct f-stop
for a given flash situation using the following formula:
F-stop = Guide number / Flash-to-subject
distance
For example, if your flash unit has a
guide number of 16 (m) or 52.8 (ft.) for the type of film you are using, and
your subject is 2 meters (6.6 ft.) from the flash unit as indicated on distance
scale after focusing, divide 16 (52.8) by 2 (6.6). The answer is 8; therefore,
set f-stop ring at 8 (f/8).
Tips for Better Results:
·
If you
are using an auto electronic flash unit with power ratio control, follow the
instruction sheets packed with flash unit.
·
Most
electronic flash units have a built-in dial or exposure table which enables you
to quickly compute f-stops based on flash-tosubject distances.
·
The
Sears 8025 Auto Flash is available exclusively for use with the Sears KS Auto
camera for automatic flash photography.
18. TROUBLE SHOOTING YOUR CAMERA
The proper operation of a precision
instrument like the Sears KS 1000 camera requires strict attention to the
correct manipulation of controls. In many cases, the camera may appear to
malfunction simply because some small detail was overlooked, or the
operations were not in the proper sequence. Before you decide the camera is broken,
there are some things you can look for.
Problem: EXPOSURE METER NEEDLE WILL NOT MOVE
TO TAKE READING.
Possible
cause: Improper
shutter speed/aperture combination for film and light conditions. Try changing
the shutter speed/aperture combination until needle reacts. Or check to see
that the correct type of battery is being used and has been inserted correctly.
Problem: FILM COMPLETELY BLANK WHEN PROCESSED,
INDICATED NO EXPOSURE HAS BEEN MADE.
Possible cause: Improper loading. Review section on
film loading and be sure you are loading the camera correctly with the film
being securely attached to the take-up spool and winding in the CORRECT DIRECTION,
that is UNDER the take-up spool. Film may not have gone through camera at all.
Problem: SELF TIMER DOES NOT OPERATE
SHUTTER.
Possible cause: Timer not rotated at least 90 degrees.
Problem:
LENS VERY HARD TO
REMOVE FROM CAMERA. STOP IMMEDIATELY!
Possible
cause: Pressure on
film advance lever causing automatic diaphragm actuating plate to press against
pin on back of lens.
THIS CAN CAUSE SERIOUS DAMAGE TO YOUR
LENS. DO NOT FORCE THE LENS! Check to be sure the
film advance lever is retracted.
Problem: FLASH PICTURES BLANK OR PARTIALLY
EXPOSED.
Possible
cause: Improper
shutter speed for the type of flash used, or improper cord receptacle used for
the type of bulb or shutter speed. Check Flash Synchronization Table carefully.
Problem: SHUTTER WILL
NOT RELEASE.
Possible
cause: Film advance
lever not advanced far enough. A full stroke is necessary to cock the shutter.
However, a ratchet incorporated within the film advance mechanism will allow
you to accomplish a full wind in a series of short strokes.
If the problems above cannot be
solved in the manners suggested, do not attempt to repair the camera yourself.
Take it to the nearest service center. A minor problem could be aggravated by
tampering.
19. PROPER CARE OF YOUR CAMERA
·
Always
carry your camera with its carrying case and neck strap.
·
Use the
lens cap to protect the lens when not taking pictures.
·
Protect
your camera from dust, dirt, water, rain, dampness, salt air and rough
handling.
·
Never
expose your camera to excessively high or low temperatures for an extended period
of time. In extremely hot climates, do not leave your camera inside closed
automobiles during the daytime or in direct sunlight. In extremely cold
climates, expose your camera to the outer air only when in use... when using,
expose your camera gradually to the outer air to prevent the lens from clouding.
If exposed to an extremely cold climate, the exposure meter batteries may fail
to operate properly. Keep your camera inside your clothing until taking a picture.
·
Never
touch the surfaces of the lens, metal focal plane shutter curtain, reflex
mirror, etc. with your fingers.
·
To
clean the lens, gently wipe it in a circular motion with a lens cleaning paper
or a soft, clean and lintless cloth.
·
Do not
wipe the camera body with chemicals, such as benzine, thinner, etc. Use only
soft cloth or cotton swab sprinkled LIGHTLY with alcohol on the camera body. Do
not use them on the lens because it can affect coating.
·
When
your camera is not in use for an extended period of time, put the lens cap on,
remove the batteries, place your camera in its carrying case together with
silica gel or other desiccant and store it in a dry and cool place, Never store
your camera in places where the temperatures are excessively high or low.
· Do not attempt to disassemble or repair your camera yourself. If service is necessary, get in touch with your dealer.
