When one reads the developing FORE
muiac given In magazines devoted TO
photography, It would be supposed that
am one could develop q negative per-
.eotly by following the Instructions
given, says a writer in the Mall and Exc
press Magazine. Lot US examine these
Instructions First, the developer Is
generally made OF two solutions called
A and 3, solution A containing the re-
duclns. agent and solution B containing
the alkail. To USE, It Is recommended
10 take two parts otA to one part OF B,
or In other proportions as may DO called
for In the formula, and there tho In,
snucaons concernig Its use generally
r,cp Tho question now to determine
IS, what exposure shall be given for this
developer In the proportions named and
get perfect results each time.
This the formula does not contain; 1t
IS like man playing slide, trombone,
4 sort OF ulip-and-suess.at-lt affair.
Some formulate do say, however, that in
case of over-exposure use less OF B,
and In case OF uEder-eIposure more OF
3. Now, how Is the amateur to deter
miro when a plate Is Nover or UNDER
exposed before development? He goes
on. on Il clear day when everything
seems Just right to get beautiful re-
suits, exposes half dozen plates all OF
the sumo make and speed, using the
same lens and stop giving each plate
the sane time. II 10 admitted that at
no two minutes In the day is the act!nic
power OF light the same. II this Is SO,
then some OF the plates may have been
over-e1poped. some under-eNposed and
come correctly TEND, but he cannot tell
until! they are developed (Which Is done
according to formula and instructions)
when some OF the results are Just right
while. others are pronounced over or
under-exposcG and fiat; and thrown Into
the ash barrel. and the amateur Is puz-
zled to know what caused the bad re-,
suits when Instructions as laid down In
the developing formula had been care
fully followed and why all the pictures
did not turn out alike when all had
been taken under apparently the same
conditions. 5
The trouble lies chiefly. am Inclined
10 Think that instead of informing the
USER how to regulate the developer In
such n manner as to- FIT the plate 1t
Is to develop. 1t Is, expected that the ex-
posure should be made to eft" the de-
veloper; at any rate, according to for
mula generally given, It looks that way.
A good rule to follow, as found by the
writer. Is to expose according to ones
best Judgment, and then develop with
developer weak In alkali, in all cases
building UP with alkaA IL the image
does not appear In a reasonable length
OF time, say, 4 minute or so. A favorite
developer OF the writer's Is us follows:
Solution A-Pyro. As grains: meta BIZ
sulphate potash, IS grains; bromide
ammonia Tor potash), sc grains; water,
Is ounces. e.. :. -
Solution B-Water, 16 ounces: carbon
ate soda, sufficient to test 40, hydrome-
ter.
For n 4x5 plate, take one ounce OF A
and add a Mttle B to It, say. a half
dram, and immense plate. II the image
does not appear in one minute or so,
add little more B. say, another half
dram and await results. Continue In
this manner until the image COM
mences to appear, when It wild be suffi-
cieEtly strong, IN alkali, and continue
development until completed. This
method Of development has, In the wri-
ters experience. In almost every In
stance proven successful. failures oc-
curing only when the exposure had
been prolonged an unreasonable length
OF time and them prolonged Intention
ally to test the speed and latitude OF
the plate. ~ n a
This method of development WIN. in
some instances, consume time. great
deal OF time, but what do a few min
rteS. or even hours, extra time amount
10 when You have the satisfaction of
knowing that your results, are certain
ant. YOU are rewarded by negatives,
rot failures?
Another good rule to follow: Never
use the same developer for the second
Plate; It is apt TO stain the plate even
though II should be Just the right
strength, as the strength of the reduc-
W
mas lost comparatively none OF its
strength Economy Is good thing to
nave around, but don't let 1t be Of the

photographer Is the loss or prints In
