If you set
Commander mode
, you’re telling the camera that
want to use the internal flash for wireless flash control. You
then need to set the flash mode and flash exposure
compensation for each and every flash group, including the
internal flash (I’ll have more to say about this in the section on
wireless flash on page <627>):
Recommendations:
1. If you’re going to use
Repeating flash
, start by first
establishing a shutter speed you’re going to use. Let’s say
your shutter speed will be 1/60. Next, use
Interval
to
determine how many flashes will be fired a second. An
interval of 1Hz means 1 times a second, so we need to
divide the lower value of our shutter speed (60) into this,
which tells us that we could have as many as 1 flash while
the shutter is open, which obviously isn’t going to
generate a “repeating” flash effect. By contrast, if your
shutter speed was 1/2 and your
Interval
was
10hz
, you
could get as many as 5 flashes into your shot. You’ll need
to jigger your shutter speed and
Interval
until you get a
meaningful potential set of repetitions. Finally, set
Times
to a value less than or equal to what you just calculated.
