a s “1/4” o r “1/8 ” m a y n ot b e a s h e l pf u l. T h e
output of one powerful ash model at “1/8”
can be higher than that of another, weaker
a s h m o d el at “1 /4.” F o r t h i s r e a s o n, t h e V 6
offers an “absolute power” mode in which EV
numbers can be used to specify an absolute
light intensity, independent of the maximum
power output of a ash model.
The power levels in guide number have been
rescaled to the absolute power scheme in EV
as below:
