Note the EV number
to wl-rich the
red
exposure
needle
points.
3 Move
the lock blltton to the
right
and,
at
the same
time, nrove the knurled wheel
until
the
green
pointer
is
set
for this EV
number.
The camera is now set
manually
for
proper
exposlrre of
the
sr-rbject
only.
If the
principal
subject
is dark against
a
very
light
background,
follow the same
procedure.
Under
certain conditions
you
rnay wish
to modify
the
recommended
film
index to
achieve
results which are filore to
yor"rr
lik-
ing. Using
a slightly higher exposure index
than
recommended results in slightly darker
transparencies,
u,hich
sonre
people prefer
when using a high-wattage
projector
and a
srnall screen.
For example,
if
32
is
the
film
index sr"rggested
by the
manllfacturer,
try
a
setting
between 32 and 64.
A
slightly
lower
index
results in slightly lighter transparen-
cies,
preferred
by some
people
when using
a
low-wattage
projector
and a
large
screen.
