Speedlight condition
Ready to fire
Fired properly
Both master and slave flash units have
fired at full output and light may have
been insufficient (or too much) for
correct exposure. Change the distance
three sec.
between Speedlights and subject or
select another aperture and shoot again
(p. 21).
Slave SB-50DX has fired at full output.
The light sensor on the slave SB-50DX
unit could not detect when to stop firing
in sync with the master flash unit. This
was because either the light sensor
window was not directed at the master
three sec.

slave SB-50DX itself or light from

the slave SB-50DX unit and/or other
slave flash unit(s), then shoot again.
