use, can best be handled by
the camera fan who likes to do
his own processing in a day.
light developing tank that can
be bought at any photo supply
store. Although processing can
be carried out in trays or deep
tanks, the daylight job is
handler, safer and more prac-
tical. And it costs less-a
point worth considering these
days.
When you try to process
roll film in trays or deep tanks
it often winds up in a Snarl
which is difficult to untangle
in the dark. During those
frantic moments when you are
feverishly trying to straighten
it out, certain parts of the
film will get more development
than others, resulting in spotty
and streaked negatives. So
the little tank with the reel
is the thing to use.
An appealing feature that
should be readily apparent is
the total avoidance Of the mess
that often accompanies tray
and deep tank developing and
fixing. No chemicals will
splash on the floor and instead
of having to wash out three
fairly large trays or tanks you
will clean up from the entire
processing job by rinsing out
one tank not much bigger than
an diversified teacup. Before
outlining the steps needed to
carry out this simplified meth
cd of home film processing,
let's see what other equipment
and supplies will be needed.
This part is for the photogra-
pher who has just decided to
take up home processing.
Few Essential Chemicals .
First, YOU will need the
chemicals. This will include
the developer, the, shortstop
and the hypo or fixing bath.
These can be bought ready
packaged so that you can mix
just the right amounts without
weighing or mixing unfamiliar
chemicals. Keep the three So
lutions in brown bottles and
keep the bottles filled to the
necks to prevent Spoilage
through excess oxidation. Mark
each bottle with an easy-to-
read label so there will be no
danger of pouring the wrong
mixture in by miSchance.
A funnel and a darkroom
thermometer are both neceSsi-
ties. A clock, watch or timer
will also be needed to keep
track of the time the film re-
mains in each solution. There
are tanks which can be loaded
in daylight and if you have
one of these you won't need a
darkroom or dark place to load
the film into the tank. If you
have one, follow the manufac-
turer's directions for loading.
If yours is an average-type
tank, it will have to be loaded
in darkroom or in some place
where no light can reach the
film during the time it is being
inserted in the tank.
Assuming that you will be
using a film tank that requires
darkness for loading, follow
these directions carefully:
Garry out the loading opera
tions in the dark. After the
tank has been closed the light
may be turned on for the bal
ance of the steps outlined. To
load the tank, first break the
tape that holds the end of the
paper tightly in place on the
film spool. Then unroll the
paper film backing until you
reach the end of the film. This
end should be inserted into the
groove of the reel. Then feed
the film onto the reel, keeping
the spool in one hand and the
reel in the other, so that your
hands touch only the spool
and paper. Never allow your
fingers to come in contact with
e the film except by its edges.
The other end of the film is
attached to the paper backing
by a piece Of tape that should
be removed when reached.
Once loaded. the reel can be
placed in the tank. Place the
lid or cover on the tank secure
ly and then turn on the lights.
Keep the Tank Filled
From now on you may work
in full light without any harm
coming to the film. Use your
thermometer to make sure all
three solutions are at the same
temperature. This should be
the temperature recommended
by the maker Of the developer.
The funnel is used to pour in
the developer and the solution
must be poured in very quickly
to prevent uneven develop
ment4 Also, be sure that the
