Olympus AZ-4 Zoom manual

Q:How should I take advantage of all of the capacities of this excellent flash?

A:We recommend that you use the Flash Auto mode (p. 34) under normal circumstances.

It will flash when conditions are dark enough to require extra lighting, and the exposure is automatically set at 1/100 sec. to avoid unnecessary flutter. There is no need to worry about lighting and the camera is easy to use. The Fill-in Flash mode is to be used under conditions of daylight synchro or slow synchro photography or other special conditions to which the Flash Auto mode cannot respond.

Q:How should I use the Fill-in Flash mode for daylight synchro or slow synchro

photography?

A:The Fill-in Flash mode causes the flash to fire regardless of the available light, as well as conditions of exposure control shown in the exposure program line graph on p. 45. (Note that the shutter speed will be slower than the normal 1/100 sec.) With regard to lighting conditions, photography will be either daylight synchro or slow synchro photography. Please see the examples on p. 37 for your reference.

daylight synchro: When photographing a
subject against a light source, the Flash Auto
mode will not activate and the subject will be
dark due to the affects of the backlighting in
his surroundings. By using the Fill-in Flash
mode, the flash will fire and the subject will
be well-lit for an attractive picture.
slow synchro: Often, when photographing at
night, if the subject is too far away from the
camera the flash will not suffice. Yet if you
use the Fill-in Flash mode, the shutter speed is
lengthened and the flash will fire allowing for	52
the possibility of photographing both the

subject and the background. Since the exposure time is longer than usual, caution is required with moving subjects. It helps to use a tripod to avoid camera shake while using this mode.
