The holiday picture-taking
season Is over. Now let your
darkroom start paying on II
picture dividends.
The next two Or three
months, while the weather Is
cold. IS the photographer's
Information period. He retires
to the comfortable warmth Of
his darkroom to develop Aims
and make prints.
For the next several weeks
this column win train sights
on the hoW-to-do-its Of
filn processing and print
making, with an occasional
aside on winter picture taking
and other seasonal topics.
Now let US proceed to your
darkroom. kitchen. bath or
wherever you have selected
to do your home processing.
To many an exposed filn Is
. tubular little bundle Of mys-
tery but actually 1t is not.
Once you get the hang Of it.
processing film is quick and
easy. II can be done In an
ordinary roll fiim tank where
only the loading Is done In
total darkness, In q day-load-
ing tank where all steps can
be carried out In full light. or
IN the same trays you win use
for print processing II neither
Of the tanks Is available. In
tray processing the entire
operation must be performed
In total darkness but this soon
becomes routine once you get
the knack Of undressing and
handling the strip Of 1ilm.
Tank Method Favored
The tank method Is recon-
mended because Of its several
advantages. When tanks are
used you avoid leaving finger
marks. development Il more
uniform and there is little
chance Of causing abrasicns
on the soft emulsion. With
the long rolls such as the
35-mrn. it Is impractical to
handle the filnn by hand In
trays unless 1t Is cut into small
lengths. and II you do this
you run the chance Of shipping
through one of your best shots.
With an ordinary RON film
tank the filin Is loaded on the
film apron In total darkness,
then placed In the tank, the
lid put on and the rest is done
In full light BY pouring the
three solutions in and out of
the tank through q hafiIed
opening that excludes light
while admitting liquids. Full
directions come with the tank
and should be followed care
fully.
Troy Method Is Exocting
Tray processing Is q different
matter. This must be carried
out in total darkness from the
moment you start to open the
roll until the negative has
been In the hypo solution long
enough to be fully fixed and
impervions to light. But. be-
fore starting on the film. the
processing setup should be
put In order. Arrange three
trays Id d row on your work
table, but not so close that
liquid splashing from one will
fall into the others. Put the
developer in the left hand
tray. the short-stop solution In
the middle tray. and the fixing
bath in the one to the extreme
right.
All solutions should be at the
same temperature. about SO
degrees F. or at the tempera-
ture recommended by the
maker. Test them with q dark
room thermometer to make
sure-a mistake can cause
oyerdevelopment, underdevel-
opment, reticulation, or even
total loss.
II the temperature Is OF,
place the tray in b larger one
holding warmer or cooler water
(which ever Is called forl and
agitate the working solution
until the correct temperature
is reached. Never add hot or
cold water to the solution.
Affix Pair Of Clips
When all is In readiness turn
on the lights and prepare TO
unwind the film from It's spool.
After 1oosening the gummed
tape unroil the paper backing
until the end Of the fiIm is
reached. Fasten . film clip to
