The procedure, which isn’t specific to any one camera, but is brutally easy
with the OM-2S:
1. aperture priority mode
2. Set shutter speed to flash sync speed
3. Set ISO
4. Mount flash and set to either TTL or auto
1. Turn flash off
2. Adjust aperture so the indicated shutter speed is one or two stops below
flash sync speed (1/30 or 1/15 on OM bodies)
3. Turn flash back on.
4. Of using auto flash (non-ttl) set iso and aperture on it)
Most OM bodies will force the shutter speed to 1/60. So this will
underexpose the background by one or two stops. If the ambient light gets
above the 1/60 the flash usually won’t fire.
I use variations of this with all my cameras as I rarely have TTL flash
The neat thing about the OM-2S is that you can effectively have a stored
exposure setting available at all times. I can have a manual exposure and
auto exposure accessible with a flip of the switch. When shooting in auto I
can see the movement of the meter and I know the general proper setting. If
the meter is being fooled I switch to my manual setting for the shot and
immediately put it back to auto.
