Introduction
Let's begin with the general operation of your camera. Handling your
camera with skill and ease may make the difference between getting the
picture and being too late or between getting a sharp picture and getting
one that's fuzzy. The greatest picture opportunity in the world can go
down the drain if a photographer fumbles with the camera, sets the exposure
controls improperly, doesn't focus properly, or jiggles the camera as the
shutter release is pressed. When handling your camera becomes second nature,
the results are consistently better pictures.
A good general rule to follow in handling your camera is not to use
force to adjust anything on the camera. Otherwise you could damage your
camera or your film. The camera controls should work easily and smoothly.
One of the most important factors in getting sharp, clear pictures is
to have a clean camera lens. You've seen what the view is like when you
look through a dirty window. Well, your pictures will have a similar hazy,
unsharp appearance if you take them through a dirty camera lens. So before
you start taking pictures, be sure your camera lens is clean.
If your camera lens needs cleaning, clean the front and back glass surfaces
by first carefully blowing away any dust or dirt. Then breathe on the surface
of the lens to form a mist and gently wipe the mist away with a soft, clean,
lintless cloth or use lens cleaning paper moistened with lens cleaner.
CAUTION: Do not use solvents or solutions unless they are specifically
designed for cleaning camera lenses. Don't use chemically treated tissues
intended for eyeglasses.
Loading
and Unloading 35 mm Cameras
In this section we'll provide some general information that applies
to most 35mm cameras. For specific instructions for your particular camera,
see your camera manual.
Always load and unload your camera in subdued light-not bright sunlight.
(This is especially important for very high-speed films.) If there's no
shade around, position your body so it casts a shadow over your camera
for loading and unloading. This helps prevent bright light from entering
the lip of the 35mm magazine and causing a streak on the first or second
picture. If this happens, the streak is usually orange or clear on color
slides or prints but dark on negatives. To avoid streaks, keep the film
in its light tight container before and after exposure.
Loading a 35mm camera is easy. However, it is possible to put a 35mm
magazine into the camera the wrong way. The film slot of the magazine must
face the take-up side of the camera; and the light-colored side of the
film, the emulsion side, must face the camera lens. If the following loading
summaries differ from the instructions in your camera manual, follow your
manual.
With a manual-loading camera, thread the film onto the take-up spool.
Make sure you've threaded the film correctly for the direction of rotation
of the take-up spool. When the film is threaded, it should have enough
tension to lie flat. If it doesn't, advance the film slowly until the rewind
knob starts to turn. See that the sprocket teeth engage the film perforations
before you close the camera back. After you close the back, advance the
film three times so you are ready to take the first picture. If you don't
do this, you could make the first exposure on the fogged portion of the
leader and not get the picture.
With an auto-loading camera, line the end of the film leader up to an
index mark along the bottom rail. Check that the advance gear engages the
film perforations and that the film lies flat.
Close the back and press the shutter release. The camera will advance
the film to the first frame.
Film in 35mm magazines is usually loaded in lengths for 12, 24, or 36
exposures. (A half-frame camera yields twice as many exposures on the roll.)
Extra film is included for a leader at the beginning of the roll and for
a trailer at the end.
Electrical contacts in the film chamber enable many cameras to read
DX-encoded films to automatically set film speed, determine the number
of exposures on a roll, and the exposure latitude of the film.
How do you know if the film is advancing? Auto-loading cameras often
have a film-running indicator atop the camera to indicate film is advancing.
With a manual-loading camera, you can use the rewind knob to check the
film. Turn the rewind knob carefully in the direction of the rewind arrow
until you feel a slight tension. This takes up the slack in the film. Now
when you advance the film, you should see the rewind knob rotate.
CAUTION: Be sure that you never turn the rewind knob the wrong way-opposite
the direction for rewinding-when taking up the slack in the film. This
could kink or jam the film. After you load the film, it's easy to forget
how many exposures are in the magazine. Many cameras offer a window on
the film door that lets you see the part of the film magazine that indicates
the number of exposures. Other cameras have a memo holder on the film door
into which you can insert the end flap of the film package; the end flap
states the type of film and how many exposures. With a manual-advancing
camera, if you think you have 36 exposures but actually have 24, you could
damage the film by tearing the perforations or you could pull the film
loose from the magazine by trying to advance the film. If you pull the
film loose, you can't rewind it back into the magazine.
If you haven't used your camera for a while, you may be uncertain if
it contains film. With newer cameras, a window on the film door shows if
film is in the camera. Or an LCD panel may display the picture number,
even when the camera is turned off.
With older cameras, it's sometimes difficult to tell whether the camera
is loaded with film or not. If the film counter indicates an exposure number,
there's probably film in the camera. With a manual-advancing camera, gently
turn the rewind knob in the direction for rewinding without depressing
the rewind button. If you feel resistance to turning the rewind knob,
do not turn it any farther. Your camera is loaded with film. The film counter
in most 35mm cameras has an S on it that resets when you open the back.
If you see the S on the counter, this indicates that the camera back has
been opened since the last exposure was made. Therefore, it's safe to open
the back again.
With most 35mm cameras, you must rewind the film from the camera take-up
spool back into the original magazine before unloading. If you open the
camera back before rewinding the film, the film will be completely exposed,
or fogged, as it has no protection from the light. Fogging generally looks
like a light, cloudy area covering part or all of a slide or print.
Cameras that load film automatically, usually also rewind it automatically.
The camera may automatically rewind the film at the end of the roll, or
it may signal you to press a rewind button or switch that begins the rewind.
Check your camera manual for specific instructions.
Because auto-load cameras require you to expose less leader film when
loading, it is possible that you'll get more than the specified number
of exposures on a given roll. But again, be aware that any shots past the
specified number of exposures (i.e. 12, 24, or 36) may be lost in processing.
IMPORTANT: When using a camera with a manual rewind knob, do not turn
the rewind knob in the direction opposite that of the rewind arrow. Such
action can seriously bend the film and possibly tear it. To prevent torn
perforations, keep the rewind button control firmly depressed in the rewind
position until you have completely rewound the film. Check you camera manual
for specific instructions.
If you don't force the film advance lever, you won't pull the film loose
from the magazine, which would prevent the normal rewinding of the film
back into the magazine, as mentioned before. Pulling the film loose usually
results from a photographer trying to make more exposures than 24 on a
24-exposure roll (or 12 or 36 depending on the roll) at the end of the
film. Forcing the film advance lever can also cause overlapping pictures
at the end of the roll. If you do pull the film loose from the magazine
and open the camera back in the light, you'll fog the film. The solution
is to take your camera to your photo dealer and ask them to remove your
film.
Each year several thousand magazines of 35mm film are returned for processing
by photographers who have accidentally wound unexposed film back into the
magazine. The most common reason for this happening is improper loading
of 35mm cameras which can cause the film not to advance through the camera
as pictures are taken. After the photographer finishes what is thought
to be the end of the roll, the film is rewound. Since the film didn't even
go through the camera, no exposures were made and all the pictures are
lost. Needless to say, this is a big disappointment.
To minimize the chances of winding the film leader into an unexposed
magazine, load your camera according to the instructions in your camera
manual. Also follow the tips given in this book about determining whether
your film is advancing properly.
When a film's leader is completely rewound into the magazine, it most
often signifies that the film has already been exposed and, therefore,
needs to be processed. You should contact a photo retailer or photofinisher
in your area for their service. If there is any possibility that the film
was used or mixed with films used to take pictures, you'll want to have
it processed.
It is possible to retrieve film leader from 35mm magazines so that the
film can be loaded in a camera. However, our research shows that in such
cases the risk of double exposure is great. It would be extremely disappointing
to re-use the film and lose both sets of images. There are instances in
which auto-advance/rewind cameras rewind film into the magazine before
reaching the end of the roll; a phenomenon called "premature rewind". The
major causes of premature rewind are film-loading and camera-operating
mishaps.
Camera Holding
When you're using a long-focal-length lens-telephoto or zoom-it's best
to hold your camera by supporting the lens with your left hand close to
the front of the camera. Hold the camera body with your right hand so you
can actuate the shutter release. Be careful not to move the focus or lens
opening settings with your left hand supporting the lens after you have
set them. A long-focal-length lens requires that you hold your camera very
steady for sharp pictures. Some photographers prefer to also use this method
to hold their camera steady with normal and short-focal-length lenses.
The way you hold your camera when you release the shutter is important
for sharp pictures. Camera jiggle is the most common cause of unsharp pictures-not
the obviously blurred pictures, but those lacking the needle sharpness
that indicates the touch of a skilled photographer.
The best way for you to hold your camera is the way that's both comfortable
and steady. Try to keep your arms against your body-not suspended in air.
Plant your feet firmly on the ground, slightly apart. Hold the camera tightly
against your face. Take a breath, hold it, and gently squeeze the shutter
release. Chances are that you'll make a picture free of camera movement.
Camera Types
The two basic types of 35mm cameras are single-lens-reflex (SLR) cameras
and compact cameras. Compact 35 mm cameras (also known as lens/shutter
cameras) include non-SLR autofocus, fixed focus, rangefinder, and "bridge"
cameras. With most of these, you view your subject through a viewfinder
that is separate from the camera lens. These relatively small cameras have
become increasingly popular, and they commonly include features such as
automatic film advance and rewind, automatic exposure, and automatic focus.
Having virtually point-and-shoot capability, a compact 35 mm camera is
an excellent choice for casual photography.
A camera with SLR viewfinder has a hinged mirror that reflects the image
through a pentaprism in the viewfinder to your eye. When you take a picture,
the mirror flips up to let light reach the film and then returns to its
original position.
Single-lens-reflex cameras are also extremely popular. One of the major
reasons for this is that it's so easy to use interchangeable lenses with
them. When you look through the viewfinder of an SLR camera, you're actually
looking at your subject through the camera's picture-taking lens. In this
way, you can change from one lens to another and immediately see in the
viewfinder the image that will be recorded on your film. This also means
that you'll see in the viewfinder some of the perspective changes we mention
in the section on lenses. A direct optical viewfinder can be made to show
approximately what will be included in the picture with various lenses.
But it's more difficult to appraise the effect of the lenses on perspective.
Another plus factor of a single-lens-reflex camera is that it's free
of parallax-the difference between what the lens sees and what you see
through a direct optical viewfinder, especially evident at close distances.
We'll talk more about this in the section on close-up photography.
Camera with Direct
Optical
With viewfinder-in lens-shutter cameras, the viewfinder is separate
from the camera lens. It shows approximately the same image as the image
on the film.
No matter what kind of viewfinding system you use, learn to use it with
ease and with discernment. Before you shoot, look behind your subject to
be sure you haven't included a distracting object. When possible, move
around your subject to choose the best viewpoint. Although this may be
like saying fire is hot, we can't overemphasize that your final picture
will include everything that lies within the boundaries of your viewfinder.
So before you snap the shutter, make sure you see in the viewfinder what
you want to see in the resulting picture.
Helpful Handling
Habits
Here are some tips to help you work more efficiently. When you plan
to shoot lots of pictures in a short time, take your film out of the cardboard
cartons and put all of the unexposed film into one section of your camera
bag. Be sure to keep exposed and unexposed film in separate parts of your
bag so you don't waste time trying to find fresh film.
When you finish a roll of film, rewind it immediately. Then if you accidentally
open the camera, you won't expose the film. Be sure to wind the end of
the film all the way into the magazine so that you don't mistakenly reload
it later, thinking it was unexposed film.
As you take your pictures, you'll probably have to adjust focus or exposure
settings or modes for some unusual situations. Suppose you go from distant
shots of a road race to a close-up of a car refueling nearby. For the distant
action shots, you'll probably want to use the servo or continuous focusing
mode to track action. For the close-ups, the single-shot mode will be more
convenient. As soon as you're through making the close-ups, readjust your
focus setting so that you'll be ready for action again. By the same
token, you may want to switch exposure modes from a depth mode for the
close-ups to a stop-action mode for the racing shots.
When you find an especially good subject, take at least two or three
pictures of it. This will give you a choice of viewpoint, pose, expression,
or composition, as well as insurance in case one of the negatives or slides
gets damaged.
Autowinders
and Motor Drives
When you want to take pictures rapidly, a handy accessory to have is
either an autowinder or a motor drive.
Autowinders are a standard feature on many 35mm cameras. For SLR cameras
without an autowinder, you can attach a motor drive to the bottom of the
camera. Both built-in winders and accessory motor drives perform the same
function: they advance the film to the next frame and cock the shutter
after each exposure. The chief difference between winders and motor drives
is speed. Autowinders advance the film one or two frames per second, while
some motor drives run film as quickly as eight frames per second-far faster
than your thumb could do it.
Autowinders let you take a series of pictures of fast-action subjects,
such as sports or parades. An autowinder is also great for photographing
the ever-changing opportunities for candid pictures of children, pets,
or people. For informal portraits, an autowinder will help you avoid missing
fleeting expressions or sudden gestures.
Some built-in winders and most motor drives offer you the choice of
two modes: single-frame advance and continuous advance. In the single-frame
mode, you press the shutter and release it for each picture you take. The
camera won't fire a second time until you release the shutter button. In
the continuous-firing mode, the motor will advance and fire the camera
as long as you hold the shutter button down. The latter mode excels for
fast action, like sports, but at three frames-per-second, you can go through
a 24-exposure roll of film in only eight seconds!
In addition to advancing the film and readying the camera for the next
exposure, both autowinders and motor drives are usually capable of performing
other tasks, including auto-film loading and auto rewinding.
Autowinders also simplify close-up photography, especially when shooting
live subjects like insects or small animals. Since these subjects move
almost continuously, you have to keep them properly framed in the viewfinder
and sharply focused, which is much more difficult to achieve if you are
continually pulling the camera away from your eye as you cock the shutter.
With an SLR camera, one minor problem is that when the reflex mirror
flips up to let light reach the film, it briefly cuts off your view through
the viewfinder. When you are shooting several frames per second, the viewfinder
will be blocked for much of the picture sequence. Composition and focusing
becomes a bit tricky. With direct-optical viewfinders, you'll get a continuous
view of the subject because the viewing lens and the taking lens are separate.
Finally, be aware that when you use a built-in flash, the continuous-advance
mode may not function because the flash needs a longer time to recharge
than the motor will allow.
