of the LUNASIX. lt

The sensitive Indicotor
Needle
of the LUNASIX
tells
you
very cleorly
whether
o scene hos
uniform distribution
of brightness or not.
With close-up
meqsuremenls, for
exomple,
you
con
wolk up
to
the
importont
pori
of the
scene ond observe
-
with
pressed

-
how the needle
behoves. lf the
importont
port
ond
the
surrounding oreo hove
ihe
identicol
brightness,
the
needle
will
not
move.
Otherwise, the needle
position
will chonge.
By
following this method,
you
con
soon
tell
if
you
hove
only the importont
port
of the scene
within the
meosuring
oreo of
your
LUNASIX.
Inci

method,
your
LUNASIX
"sees"
only the light
which folls
on
thot
port
of
the scene
which is focing the comero
-
in other
words the
porl
which will be
photogrophed.
The result
of this
meosurement
does not
toke
into
occount the colour
or brightness of
ihe
scene itself. Thus, incident

is
ideol
for the
previous
exomple with exten-
sive
very bright or
very
dqrk oreos
-
it
will
give
you
perfeci
results.
