This
problem
does
not
arise,
however,
with Sekonic's
incident
light
meter.
The
reflection
factor
for
fresh
snow
is 7O%.
lt is
60%
for
'city'
or
old snow.
With
your
Sekonic
you
compensate for
this
reflection
mathematically
and
thereby avoid mistakes.
You
find
the shutter
speed
by regular
incident
light
measurement
and
increase
it
by
I/

or L/2.
For
example :
When the
measured
shutter speed is LlL25 at f

Note 1:
Over-exposed

lt
is
therefore
advisable,
when
a
choice
is
possible,
to use the faster
shutter
speed.
Note
2: The correction

variations
when determining
