ESP Metering is the mode to set for general use. In
this mode. you don't have to worry about how the
picture will turn out. All you need do is press the
shutter release. Even in trickly situations such as
sharp backlighting, the camera responds f lexibly to
give you correctly exposed shots. This mode
assures trouble-f ree shooting even with the kind of
pictures that often turned out as failures because
the exposure was wrong. ln fact, ESP Metering \{
greatly increases the range of auto exposure tech-
nology. The following examples should provide a ,$*"N
useful reference.
* When taking pictures in ESP metering mode, acti-
vate the viewf inder display by pressing the shutter
release button lightly, then shoot.
Subjects for which ESP Metering is Specially Effective
r Backlighting
With center-weighted average metering, this kind of
situation tends to leave the subject's face pitch
black. But ESP Metering assures even the fine
shades of the subject's expression are faithfully
conveyed. For the best results, try to keep the
main subject fairly near the center of the composi-
tion. Check for the ESP Metering symbol (D in
the viewfinder.

GUIDE TO SELECTION OF EXPOSURE MODT
v tewltnoer
lndicatio n F eatu res
1 This is the ideal normal mode for snapshots and general photography.
2 When this mode is set the camera automatically decides both the shutter
speed and the aperture. Fully automatic exposures are possible over a wide
range of subject brightnesses.
3 You can concentrate on following the subject in the viewfinder without
worrying about exposure or shutter speed settings.
4 lf you set an intermediate aperture on the lens, the program a.utomatically
becomes a continuously variable program.
1. This is basically an aperture preferred mode, but it is possible to use it also
as a shutter speed preferred system. This mode is the one to select when you
want to put your creative ideas into the picture.
2. In this mode you can concentrate on special depth of field effects, adjusting
the aperture to determine whether the background, etc., will be blurred or in
clear focus.
r Here the background is blurred to make the main subject stand out. (wide
open lens aperture)
r Here the background is also in sharp focus, giving a feeling of greater spa-
ciousness and expansiveness. (Stopped down aperture)
3. You can concentrate on shutter speed effects (blurring with motion. etc.).
I Here a fast shutter speed arrests the movement of the subject, giving it a kind
of timelessness. (Wide open aperture)
r Here use of a slow shutter speed results in a blurred subject, emphasizing the
sense of speed. (Stopped down aperture)
1. In Manual Mode, both the lens aperture and the shutter speed are set by
hand, giving free reign to your experience and 'feel'for the picture situation.
2. Use when you want to keep the same exposure settings regardless of the
brightness of the subject.
3. Use for "Bulb" photography when the shutter is both opened and closed
manually.
4. Use when you are basing the exposure on the values given by a separate
exposure meter.

The OM-PC is designed to provide "OTF" Auto- matic Exposure with Olympus T-Series electronic flashes. There is nothing to set since exposure is determined by the sensors in the camera body itself . You can even adjust exposures using the compensation dial on the camera. Because it directly measures the light at the film plane, it does not allow for flash exposure error utilizing the sensor built into the flash. Such special techniques as bounce flash,diffused illumination and ultra closerps can now be ac- complished with full automatic ease. Combined with T-Series flashes, the OM-PC per- mits flash exposure in three modes: "OTF" pro- grammed exposure mode, "OTF" automatic ex- posure mode and manual mode.View original page 26
