 there  are  other  developers  that  you  can  buy  already
 made up  in bottles,  or  in the form  of powders  or,,Cir-

 of hypo  in the wrong  place.
      It  will  be a good idea now  to see how  to  develop  a
 single quarter  plate, whether  that  is exactly  what  you
 will actually do or not.                                                           II

what  you  repeated  six  times  over ? )  place   it  in  the

over  the  plate  at one sweep and  cover  the  dish  with

  As the plates are fi.xed the)' are put  in a washing  tank,
 which contains  a grooved rack  to hold  the plates upright
 in  the  water,  and washed  in  running   lvater  or  a great
nnmber   of  complete  changes  of  water   for  at  least  an
 hour.  You  should  then  take one plate  at a time,  hold
 it  in a gentle stream  of water  under  the  tap, and very
 tenderly  rub  over  the  gelatine  with  a plug  of  cotton
 wool.  Remember  that  the gelatine  is very  soft and that
 a touch with  the finger nail will damage  it.  Then squeeze
 the cotton  wool out and wipe  off any drops or streaks  of
 water from the gelatine.   Stand the negative on one edge
 on a shelf, out of the dust and not near a fire or in the sun,
 and leave  it to dry thoroughly.   This  will  take some hours.

     It is interesting to watch the development  of a negative,
 but   if you do only one plate  at a tjme  you may  find   it
 too long and  tedious.   You  can  increase  your  rate  of
working  bv  putting  two  quarter-plates   at  a time  into
 a half-plate  dish, and  using  from  three  to  four  ounces
of developer.   What  you  have  to  learn  is how  long  to                                                                         A7',
continue  development.    This  you  can  only  do  after
some practice,  and watching  the appearance  of the back
of the plate  will  be your  best guide, as long as you  use
the same kind  of plates and the same  developer.
  Another  way   is  to  develop   for  a certain  fixed  time,
according   to   the   de-
veloper you use and the
temperature.    You  can
buy  a  developing   tank
into  which  you  put  a
number  of plates at once
and  fill  the tank  with  a                                                       ,l

        the  tank   into  a  light  room    if  you   like.   With  most
        patterns  the  tank  has  to be turned  over  occasionally.
       The advantages  of this kind  of development  are that  the
        plates are not exposed  to  light  at  all,  they  do not  have
         to be handled,  and  they  are sure  to  have   just  about
        the   right   development,    provicled   the  exposure  was
        reasonabl)'  correct,  and we have  already  seen to  that.
                 It   is almost  impossible   to  describe  what   is  a good
        negative.  The  best  thing  you  can do  is  to show some
         of  your  own  to  an  experienced  photographer.       If  he
          tells you  that  you develop  too long,  or not long enough,
       you can  easily  put  matters   right  next  time.   Another
       good plan  is  to  stucly  your   prints.      If  they  look  dull
        and, "  flat,"  with  no  nice  contrasts  of  light  and shade,
        your  negative  is too   "  thin."   That   is  to say  there  is
        not enough  clensitv or strength  in the  silver  drposit  and

   Lay one of your  negatives  face downwards,   in a good
 light,  on printed  paper.   The  e'dges of the  plate  should
 be clear glass, or nearlv
 so, but  there  should  be
 scarcely  a sign  of  clear
                                                                                 \ glass   anywhere    else  ;
 and through  the densest
 parts you should  just see
 the   print   underneath.
 When   your   negatives
are  quite  dry,  polish  the
 glassside.  The film  side
should   already  be  per-
 {ectly  clean  and have  a
smooth,   silkv   surface.
Take    care   never    to
scratch  it,  or  get  finger
marks, or dirt,or  stains of
anv kind upon  it.  You ma)' pack yonr negatives film to
film  in  the  plate  boxes, but  at any  rate  vour  best ones
should  be  more   carefully   stored.   The    " Negasys  "
trile  provides  a splendid  means  of  taking  care  of your
negatives.  Each  negative  has an envelope  of  its own,
with space for  its  title and other  particulars,  and  all the
envelopes go into  a strong  box and there  is a numbered
index  so  that  you  can  find  at once any  nega^uive you
want.  Good  negatives  are  worth   taking  care  of.
  Perhaps,  after   all,  you  are not  going  to use plates,

A good deal of  it  applies  just  as much  to negatives  on
film.
  The gelatine and  silver we found  on the glass plate  is
often coated on a strip  of  thin  celluloid.   This  can be
                                                                                r o l l e d

posure, in  da_u-light.  This  is a great  advantage.    trilms
are much  lighter  than  plates,  too, and take up muc:h less
space, so  that  they  are  particularly   convenient  when
travelling.   And  glass negatives  are liable  to be broken,
while  films  are  not.   You  can  store  up  film  negatives
in much  smaller  space than  the same number   of glass
ones would  require.   Against   all  this you must  set the
fact that  fi.lms cost considerably  more  than  plates  ;  but
you cannot  expect so many  advantages  without  paying
for them, can you ?
  When  you  handle  films  do  not  forget  that  there  is
gelatine on both  sides, and not only on one as in the case
of  plates.  One  side has  onlv  plain  gelatine,  which   is
put on because the  film  rvourd  curl up  very  badly    if   it

can  possibly  manage  just  to  see what  you  are  doing.
First you draw the strip backwards  and forwards through
clean water,  raising  first one hand  and  then the  other,
and keeping  the  bottom    of  the  loop   of  film   in  the
water.  You  do this  tiIl  the gelatine on  both  sides is so
wet  that   the  fi.lm  is limP.
  Then you do the same sort  of thing  through  a dish  of
developer,  r,r'ith enough  solution  in   it  to develop  all  the
six negatives.  You can get a special dish for this purpose'
fitted  with  a  roller   or
bar,  under  which   the
film passes to keeP  it  in
the solution.  When the

 at   least  ten   minutes.

 scissors into  six  separate  ncgatirres.
   This,  you  can  imagine,   is  a  rather  tedious  process'

if you  are going  to use films  a good deal   it  will  pay you
to adopt  it.  The  " Standa  "  fi.lm tank  is made specially
for  dealing  with  six-exposure  spools.   You  can  put  the
frlm  into    it  by  daylight  and  develop   for  a certain  time,
as you  found  you  could  do   r,vith  plates   in  a  tank.
Developing,   fixing  and rvashing  can  all be done  without
any manual  labour,  and  the  film  does not come out  into
daylight   until    it  is ready  to hang  up  to  dry.   This  not
only  saves time  and  trouble,  but  the  films  are notliable
to  be damaged  by  handling,   or  to  be fogged  by  long
exposure  to  the  light   in  the  dark-room.
  However  much  care  you  take  about  exposing  your
plates  and  6.lms,  and  in  developing   them   afterwards,                 4lr
you must  not  expect  every  negative  to be a perfect  one.
You   will  learn  later  on  in  your  work   that  many  things
can be done to irrtprove  negatives.    Therefore  you shorrld
not  destroy  any  that  you  are not  satisfied  with.   Keep
them   till  you have  further  knowledge  and then you may
flnd  ihat  you  can improve  them  wonderfully.    Always,
though,  you  should  strive   to  get as good  a negative  as
you  possibly  can.
  No doubt  you  think  that  the making   of negatives  is
a terrible  task, now  that  you have read  all  this.   But
you  must  not  imagine  that  at  all.  You  see, you  will
not have  to do  all the thines  that  have been described,

but  only  one set of them,  according  to whether  you  use
plates  or  films  and what  method  you  adopt  for  dealing
with  them.   Whatever   you  have   to  do  will  be  quite
simple,  and when  you  have  been  through   the  little   set
of operations  once or twice  you   rvill  think   of nothing    it.
You  go  through   a  far  more  complicated   performance
every  time  you  dress  yourself.
   Stick  to one developer   till  you  are thoroughly   familiar
with   its  working  and  then,  whenever  you have a batch
of properly  exposed  plates  or  films,  you  will  be able  to
set  to  work  and  feel  cluite  sure  that  you  are  going  to
turn  them   all  into  good  ciean  negatives.   And  having
finished  your  negatives  do  not   forget   to  take  proper
care  of  them.   They  are  easily  damaged.

        have seen that the finishe<l negative lets light \aOat
    I    pass through  it  in varying  quantities accorcling
        to  the  greater or  less density  of  the  silver
 deposit.  Most light passes through where the negative
 is clearest, and that   is just where the shadows in the
 subject were darkest.  Least light passesthrough where
 the silver  is densest and that  is where the Iights were
 brightest in the subject.  The purpose of the negative
 is to produce a positive ;  that  is, a picture with  lights
and shadescorresponding to those in the original subject.
  These positives are generally made on paper and there
are several distinct methods of protlucing such prints.
Some of the methods have many varieties, so that there
is a tremendous variety  in photographs.  you  should                 t\i
now learn a little  about some of these ways of making
prints.  This will help to give you an idea of what you
would like to take up  first.
    It  will be just as well to try a simple one to begin with.
There is a class of photographic papers known as ,,self-
toning papers " and making  prints on one of these is
about as simple as any photograph printing can possibly
be.  The only chemical used. is hypo, and you already
have that  for your  negatives.  Then you  will want a

  A  printing  frame  is a strong  frame  of  lvoocl,  with  a

                                                    jointed  and

                                                while    the

                                                          tight.  You

a printing  frame  and  a negative   (rvith  glass side  quite
clean).  Open  your  packet  hy  slitting  open  one  end,
as you  cut  the pages of a book.  The  paper has other
wrappings  inside.  When  you  take  a sheet out wrap  up
 the others and put  them  back  in  the envelope.    l)o  all
 this indoors  in a weak  light,  so that no strong  light  falls
on the paper even  for  a moment.   You  will  fi.nd that
one side  of  the  paper  is sensitive  to  iight  and   if  this
 " right  "  sicle is not  gloss!,  at any  rate   it  will  not be so
 white as the   " wrong  "  side.
  Take  the  back  right  out  of  the  frame  and  lay  the

 again and fasten the springs.   The paper  is now pressed
 tightly   and  evenlv   against  the  negative.   Place  the
 frame  out  of  doors-not   when    it  rains,  though-in    an
 open  position  where  plentv   of  light   falls  on  the glass
 of  the  negative.   Do  not  place   it  in  vivid  sunlight.
   After  a rvhile  take  the
 frame  indoors  out  of the
strong  ligl-rt, unfasten one
 part  of the back  (taking
care  not   to  move  the
other)  lift up the edge of
the  print  and  see horv  it
 is getting  on.    At   first
the  picture   will  be weak
and   faint.    By-and-by
you   rvill   find    it  is  just
as dark  and  strong  as
you would  like   it  to be.
If you take  it out  of the
frame  you  will  have  a
beautiful    photograph,
showing   all   the   detail
and   light   and   sh ade
that   the  negative  has
stored up  for you.   But  you  see that  this would  never
do  ;  for light  will  still  act on  the paper, and every time
vou look  at your  print  the light   rvill  fall upon   it and soon
darken   it  all  over.   You  can  "  fi.x "  the  print   in hypo,
somewhat   in  the same way  that  you  did  yollr  negative

be learned by experience  rvith  this  paper-judging   when
the printing  has gone far enough,  but  not  too  far.   yotr
will  soon learn how much  extra  strength   to  ailow.
   The  print,  as  it comes from  the  frame, must  be put
out of the light  (say in a box or drarver)  till you are ready
to finish  it.  No doubt   it  will  have  to be fixecr in hypo.
It mav,  or may  not, have  to be washecl first,  but   it  will
certainly  want  rvashing  afterrvards.
    This  is not  very  definite,  is  it ?  I{ow  long must  the
prints be  in  the hypo ?  what    is the  strength  of  the
hypo ?  How  are the  prints  washed ?
    well,  whatever  paper you  buy  you  r,vill rind  with    it

exactly  what  you  are  told.    All  self-toning  papers  are

 not  to  be treated  aiikc,  but  each one  exactly  as  its
 maker  tells  you.
    At  the same time  there are certain  principles  or rules
 that  apply  to  all  self-toning  papers,  ancl some  of these
rules apply  to other  papers  too.   E,xcept while  printing
do not  allor,v strong  light  to  fall on the paper  until   it  is
frxed in the hypo,  and the less weak  light  falls on  it  the
better.   Avoid  touching  the  sensitive  side as far as vou
possibly  can.  Use  fresh  hypo-quantity     and  strength
accordins   to   instructions.   Keep   the   prints  moving
constantlv   in  the  hypo
by  repeatedly    dra'ring
out   the   bottom   print
and placing   it on top.
   Now    try    to   learn
once for  all how  to rvash
prints  thoroughly.    To
commence  the  rvashing,
place the prints  in a dish
of  clean  rvater.  Good
large  dishes  are best, so
tha'u  the  print.s  do  not
have  to  lie in a heap.  In
two  or three minutes   lift
up one print  and  let the
lvater   drain    off   at  a
corncr  ;  then  drop    it   into  a  second  dish   of  clean
rvater.  Continue  till  all the prints are in the second dish.
E,nipty' the  first  dish, rinse  it out, and  re-fill  it.   Nou' get
thc  prints  back  into  this, one by  one.  So you  go on.

  If  the  prints  are changed  thus  into  clean warer  every
 five minutes,  for  at least an hour,  y-ou may  feel sure th.at
 they are r,vell washed.     If  ther paper  is thick,  or the r,vater
 very   cold,   increase
 the time  of u'ashing.
  It  is time well spent.
    Nearly    all   self-
 toning  papers  give  a

 colour  unless you do

   A  paper   that  shows  the  picture   after  you  have

that  shorv nothing  after  you  have exposed them,  any
more  than  your  plate  did   ;  and  you  have  to  develop
them  very  much  as you  did  vour  plate.      If  you  take

 special kind,  for  it gives you  a print  of a pleasing  colour
 r,vithout vour  having  to use a  " toning  bath  "  to  get  it.
 With  most  P.O. P.,   if  you  onlv  put  the  prints  into  a
fixing  bath  the  colour  you  get  is not  nice  at  all.  So
for these you have  to use another  bath  first  to  alter  the
s6lsur-a     " toning  "  bath.   Again  1,'-oumust  follow  the
instructions.   The  general processes are  :  Wash,  tone,
lvash,  fi,x, wash.  You  can get a bath  that  will  tone and
fix  at  the same time   ;  but  you had  better  not  use this
till  you know  a good deal more, and  then, most   lil<ely,
you  rvill dec.ide not  to use it  at  all.     It saves trouble,  but
you  should  not  mind  how  much  trouble  you  take  to
turn  out good work  that  will  keep good.
   The  great advantage  of a printing-out  paper  is that

 about keeping the  clishes clean, and  alwavs  taking  care
 that the hypo  clish especially  is used  for nothing  erlse.
   The  drarvbacl<  to  a  printing-out   paper   is  that    it
                                     requires   daylight,   So
                                       that  dull and wet wea-
                                           thcr,  ancl short  winter
                                   days, are against  turn-
                                      ing  out  prints  quickll'.
                                                           It  is never wise, either,
                                        to leave partlv exposed
                                        prints   in   the  frames
                                  from  one day  to  allo-
                                        ther,  or  the  negatives
                           may be stained  by  the
                                        silver   in   the   paper.
                             You  rvill be glad, there-
                                             fc-rre,to l<now  of a ivay
                                         of making  prints  with-
                                   out  using  davlight,  so
that you can also u'ork indoors  in the evenings.
   For this purpose there  is another  kind  of paper known
as " gaslight  "  paper.   This  is so named because  it can
be carriecl through  all the necessarv processes by  artificial
light.    It  must  be kept  frorn  clay'light altogether,  and
also from strong  artificial  light.   The paper  is taken from
the packet, and placed  in  the  frame,  in any  artificially
lighted room  ;  but   it must  be done  at a good  d.istance
from the light,  or in the shadow  cast by a screen of some
kind.

a strong  light    ; and to get some idea of the right  exposure
you can expose a quarter  of the plate  for a certain  time
(the  instructions   will  give  you  help),  the  next  quarter
for  double  the  time,  and  so on.  A  piece  of cardboard
as close to the negative  as possible, can be used to screen
part  of  the  plate  so as  to  give  four  different   times  of
exposure  to  the same  piece  of  paper.   Afterwards  you
can see which  of the  four  strips  of the prints  is best, and
then  you  will  know  what  the  right  exposure   is  for  that
negative,  or any other  like   it  in density.   But  you must
be most  careful  to keep  the frame  at the same dist,ance
from  the  light  whenever  you  are exposing   ;   if you  vary
the distance, even
a    little,     it    will
make  a great   dif-
ference  in the  ex-
posure.
    This    gaslight
paper   is  one  of
those   that  show
no  change  after
exposure;  there  is
no  picture   to be
seen. That  is whv
you must  be so careful  about  the  exposure,  for   if   it  is
wrong  there  is no remedy.   You  pour  over the exposed
paper  the developer  reconrrtended   for  it, and the picture
 appears-not     slowly,   as  the  image  appeared   in  your
 negative,   but   in  a few  seconds.  The  print  has  to  be
 fixed   in  hypo   afterwards,   of  course.  Remember   to
