For example, if you wish to f ire a
s e r ie s of a s h e s t h at l a st s for
0.5 second at a frequency of 10 times
per second (i.e., 10Hz), the number of
a s h e s w o u ld b e 5.
Similarly if you wish to f ire
10 a s h e s at a f r e q u e n c y of 100H z,
t h e a s h s er ie s w o u ld la st for
0.1 secon d.
T h e a s h s e r ie s d u r atio n is u s u a l l y
equal to the shutter speed. However,
it may be necessary to use a longer
shutter speed that exceeds the ash
series duration in order to expose
for ambient light. Alternatively, it
may be necessary to use a shorter
shutter speed, and a slightly longer
series duration as a safety margin.
