Well assuming a fully manual calculation of flash exposure or the flash set
to "normal auto" with say an aperture of f8. As long as the ambient light
would lead to an exposure of > 1/60 (say (1/8), first curtain opens fully,
flash fires, OTF metering sets the second curtain on it's way, the resultant
exposure is probably about 1/60 f8. If the flash is giving less light than
expected then the OTF metering just holds back the second curtain until the
ambient makes up the difference. You may get overexposure if your manual
flash calculation isn't correct or if the "normal auto" mode gives more
light than it should.
