11 HOW TO CHOOSE A SHUTTER SPEED
11 How to Choose a Shutter Speed
The shutter controls exposure by the length of time it remains open. The basic
function of shutter speed is to provide correct exposure, but you can also use it to
control the expression of your sub jects motion and to control the eect of camera
movement. 11.1 Freezing Motion
The faster the sub ject is moving, the higher the shutter speed required to stop the
action. To freeze the motion of a pedestrian, for example, choose a speed of at...

11.2 Blurring the Sub jects Motion11 HOW TO CHOOSE A SHUTTER SPEED
11.2 Blurring the Sub jects Motion
Blurring part of the picture can give a convincing sense of action. To blur the sub-
ject, simply set a shutter speed which is too slow to freeze its action. In this photo
it was blurred at 1/15 sec. 11.3 Panning
You can blur the background while keeping the sub ject relatively sharp by pan-
ning. Choose a shutter speed suitable for the sub jects motion and release the
shutter as you follow the movement,...

12 APERTURE
Blurring part of the picture can heighten the sense of action. In most cases, how-
ever, image blur is undesirable. To avoid blurred pictures from camera movement,
choose a shutter speed of at least 1/60 sec. for handheld shooting with a standard
lens.
With a telephoto lens, it is advisable to use faster shutter speeds. The rule of thumb
is to use a shutter speed no slower than the reciprocal of the lens in use. This means
that for a 100mm lens, the shutter speed should be at least 1/125...

12 APERTURE
The smaller the aperture, the wider the range of sharpness. This is illustrated by
the picture above which was taken at f/22. Compare it with the photo to s right.
This extended depth of eld is especially good for such sub jects as landscapes.
The larger the aperture, the narrower the range of sharpness. An aperture of f/1.4,
for instance, can isolate your sub ject from its surroundings. This is often used to
blur a disturbing background in portraiture.
Depth of eld is also greater the...

13 EXPOSURE MODES
13 Exposure Modes
The New Canon F-1 is basically a manual-exposure camera capable of through-the-
iens, full-aperture metering and stopped-down metering with the Eye-Level Finder
FN. It can be converted to automatic exposure (AE) simply by attaching the suit-
able AE accessory, such as the AE Finder FN for aperture-priority AE, or the AE
Power Winder FN or AE Motor Drive FN for shutter-priority AE. Manual exposure
is still possible with one or both of these accessories attached.
The...

13.2 Stopped-down Metering 13 EXPOSURE MODES
[For this mode. the AE Power Winder FN or AE Motor Drive FN must be attached
to the camera and the lens set to the A mark.]
3. Aperture-priority AE
Set the lens to the desired aperture and the camera automatically selects the proper
shutter speed according to the lighting conditions. This AE mode is useful for
portraiture and still photography such as landscapes where depth of eld is of im-
portance.
[For this mode, the AE Finder FN must be attached to the...

14 METER MODE SELECTOR
14 Meter Mode Selector
There are three ways to turn on the meter, each designed to suit particular metering
requirements. To set a meter mode, simply turn the mode selector so that its index
aligns with the desired setting.
NORMAL
The meter turns on only while the shutter button is pressed halfway (except for B
and  S  settings on the shutter dial). This mode is suited for AE photography.
HOLD
The meter turns on the moment you press the shutter button halfway and stays on
for 16...

With the Eye-Level Finder FN, an aperture scale and the pre-set shutter speed
are displayed to the right of the eld of view. Focusing Screen FN-PE, which
oers selective-area metering, is supplied with the New Canon F-1 Eye-Level Finder
combination. 16.1 Match-needle Metering
1. Turn the shutter dial to the desired speed.
2. Look into the viewnder and focus the sub ject.

3. Place your sub ject so that it lls the rectangular area in the center of the
viewnder. This shaded portion is the light measuring area of the cameras
silicon photocell and is 12% of the eld of view. 4. Turn the meter mode selector to the desired mode. Then lightly press the
shutter button halfway to turn on the meter.
The meter needle should be outside of the exposure warning zones. If it is
in either zone, turn the shutter dial until the meter...
