0 Choose B (bulb) setting or a shutter speed long enough to

■ accommodate all of the flashes you will fire. For example:

tOHz will fire the flash 10 times in one second. Firing the flash 5

times at tOFIz takes 1/2 second to occur, so you should set the
shutter to a speed at least as slow as 1/2 second.

Firing the flash 6 times at 8Flz takes 6/8 second to occur.

However, because your camera does not have a shutter speed

of 6/8 (0.75) second, you should set it to the closest slower

shutter speed, which is one second.

As you may have noted: to calculate the speed necessary for
the combination of number of flashes and speed of flashes, you
should divide the number of flashes by the speed of fhe flashes
(Hz), then convert the fraction to a decimal number and set the
shutter speed that corresponds to the calculated value.
