Turn the remote flash units on. They all either need to
be connected to an SU-4 or have a built-in SU-4 type

Since the remote flash units may be more powerful
than the internal flash, you may have to adjust the
position of the external flashes to be further from the
subject (or use their diffusion domes to limit their
power). When I’m feeling especially daring and
creative, I actually set my exposure in Step #4 to
underexposure and then
try
to get the remote
Speedlights to fire a little hotter than the internal flash,
but this is a big trial and error process you’ll just have
to experiment with yourself.
