allows you to use a wider aperture

exposure.
11.2.1 Characteristics of HSS Flash
Compared with normal single-burst
ash, the HSS ash provides
continuous and constant illumination
for the full duration between the
f irst curtain opening and second
curtain closing. The contribution of
HSS ash to the exposure of the image
is therefore different than that of a
n or m a l a s h:
1. The output power of the HSS
ash f ired by the RF60X is
different from that of a normal
a s h. T o co m p e n s at e 1 E V e x p o s u r e
loss in your camera setting, you
need to increase the power level
of a HSS ash by 2EVs. Check the
GN table below for comparison:
