Kodak No. 2 Folding Autographic Brownie - Page 51

Lenses should
be
frequently
examined.
Rernove
the front
of
the camera from the
back, as
described
on
pages
5 and 6
(when
there
is
no film in it)
then
open
the front
of
the
camera, extend the
bellows
and
open
the shutter. Adjust the shutter
as
when
rnaking
a Time Exposure;
the largest
stop
(Il.S.4)
should
be
in
position.
Hold
the
camera so
that
the
front
is
towards the
light,
then
look through
the lens from
the
back
of
the
camera,
and if the
lens is
found
to be
dirty,
it
should
be wiped,
both
front
and back, with a
clean,
soft
linen handkerchief.
In summer
weath-
er this needs
special
attention.
Large
spots
of
dust or
dirt
on
the
lens
will
cause de-
fects in
the
picture,
r,vhile
if
the
lens
is
evenly
covered
rvith
a
film
of dust,
dirt
or
moisture,
the
effect will
be to
cut
off a
great
deal of
light
and
make
the
picture
under-timed.
