to use
rollfilmsin
Sinarview camerasand in numerousother cameras.
Thanks
toits specialdesign,theSinar

Working
withthe SinarRollfilmHolderis significantlyeasierbe-
cause it is no longernecessaryto removethe focusing

the choice
of five different
picture
formats.With a single

the loss of a picture
when the rollfilm
holderisloadedwithfilm.

Making
exposureson film in rollfilmholders
is basically
similartomaking

Insert

drawthedarkslide,
makethe

push

Useone hand
to liftthefocusing
screen
frame
andwith
the otherhandinsert
the rollfilm
holderinto
the space
between the film holder seat and the focusino frame
holder
(Figure

Sincea rollfilm
holderis
thicker
thanaconventional
sheet
film
holder,
it is desirable
to remove
thefocusing
screen
framewith
itsmechanism
(when
thereis
one).Thatwould
prevent
anysignificant
and
unintentional
changeincam-
eraadjustments.

SinarRollfilm
Holder
Zoom2canonly
beusedoncameras
on which the focusing
screenframe liftsoff by at least
2.5cm (1")
from
thefilmholder
seat.
Sinar Rollfilm Holders 6 x 9 cm and 6 x 7 cml
SinarRollfilm
Holders
6x g cm and6x 7cm canalsobe
usedon
cameras
onwhich
themaximum
displacement
of
thefocusing
screenframefrom
the

seatisless
than2.5
cm (1").
When
thatisthe
case,thefocusing
screenframemust
be
removed.
The rollfilm

is then
attachedto thefilm

seat
by means
ofthe
Graflock
sliders.
Making the Exposures
Figure10
Before
making
the exposure,
thecamera'sshutter
must
be closed
andtheaperture
setto the required
stop.
Then
the darkslide(16)
is drawn
untilit is blocked
and
thenthe
shutteris released.
Next,
the
darkslide
(16)
is reinserted.
It is also
possible
to release
theshutterwhen
the dark-
slide
is not
drawnor only
partially
drawn.This
causes
a
blankora frame
onwhich
onlya portion
ofanimage
has
beenexposed.

A film advance is possible at any time,even
whenthe
darkslideis drawn.But this is advisableonly in excep-
tionalsituations
(as in steppedexposures). Forthe sake
of safety,one should always reinsertthe darkslideand
advancethefilm immediatelyafterevery

Since

to indicate

For
