The longer the shutter speed/exposure time or
the faster this movement, the more clearly the
two – superimposed – parts of the picture can
differ.
With the flash fired at the normal time, at the
beginning of the exposure, i.e. immediately after
the 1
st
shutter curtain has completely opened the
film window, this can even lead to apparent
contradictions, such as in the picture of the
motorcycle (top left), which is being overtaken by
its own light traces.
The LEICA R9 gives you a choice between this
normal flash firing time and synchronisation with
the end of the exposure, i.e. immediately before
the 2
nd
shutter curtain begins to close the film
window again. In this case, the sharp image is
located at the end of the movement. In the
photograph (top right), this flash technique gives
a natural impression of movement and dynamics.
The flash moment is set using the synchronisati-
on selector (1.7):
• Position I: Flash fired after the 1
• Position II: Flash fired after the 2
curtain.
Notes:
When using the flash sync time and faster shut-
ter speeds, in terms of the image there is no dif-
ference, or only for rapid movements, between
the two flash moments.
