    No matter what kind of a negative you have there  is
a grade of Rexo that  will produce the most perfect pictures
possible to  obtain.   Rexo  is supplicd  in  three  distinct
grades-Rexo  Hard,  for thin, weak,  flat negatives.  Rexo
Normal,  for  negatives of normal  or average  density  or
contrast.  Rexo  Soft,  for harsh, contrasty negatives and
for producing  soft effects with any negative.  Rexo possesses
lllarvelouslatitudein Exposureand Development
    These features eliminate wasted orints and make Rexo
the logical choice of amateur, commercial and professional
photographers.
    Rexo  is uniform   in  quality  and  produces  pictnres
marked by beautiful gradations,  purity  of the  highlghts,
and transparency ofthe shadows.

Instructionsfor OperatingThe
    RexoetteCameras
   Do  not  attempt  to  loatl  or take  any  pictures  with  the
Rexoette   until  you  have become  thoroughly   farniliar   with
cvery  part  of  the instrunent.   Take  especial care to  learn
the  construction  of  the  shutter:  s'ork   lt  for  time  and  in-
stantaneous exposure. Read carefullv  the follon'ing  instruc-
tions,  The most important  thing  to be rememberecl in picture
taking  is that no w-hite light  (inclucling gas, electric or lamp
light)  should be allorvecl to  strike  the film, eren  for  a frac-
tional  part  of a secontl, until   it has been iler.eloped and fixecl.





It  is therefore best that  the loading  anrl unloading be clone
in  a subtluecl light,  for  after  the  seai on the f1m  is broken
                                              -  l -

there  is a possibility  of  the eclges becoming fogged  if  care
is not taken  to keep the biack  paper dran'n  tightly.
    Bef-ore loading.the  camera, try  the shutter  to see that   it .rs worKrng properry.

To Load
   To load, release the trvo corner catches (D)  at the rear
of   the  camera.   The  back   of  the  camera,  rvhich   is
hingeal on the lower  siile can  lol'  be opened.  Next  <lraw
out  the  winding  ke1- as  far    it   s-itl  go.   This  will  release
the  roli  holder permitting   its  n-ithcltan-al from  the camera
box.

              Stop or Diaphragm
   All  Rexoette cameras are supplieci with  a diaphragm  plate
having  three  clifferent  sizeil  openings,  rn'hich regulate  the
amount  of  lieht  that  is allon'ed to reacir the  fllm.
  The  largest  opening  is  for  making  snap shots  in  bright
sunlight.
  The  meilium  opening   is  for   interior   time  exposures, see
speeia.l tlirections  uniler Time Exposures Indoors,
  The  smallest  opening  is  for  making  time  exposure  out-of-
doors on cloudy  days. Never  use the smallest  stop  for  snap-
shots.  See special  ilirections  unrler  "Time   Exposures  Out-

\Yith  slide  (B)  in  normal  position  the  largest  opening  is
 in piace; to use the metliurrr opening dlaw  out the slide until
 the  locati.ng spring snaps into   first  indention;   to  use the
 smallest  opening  ch'arv out  the  slide  until  the  spring  snaps
 into  the seconcl inclentiol.
      Instantaneousor Snap Shot Exposures
   fn  making  instantaleous  or snap shot exposurcs use the
largest diaphragrn stop.  Snapshots are usuallv nade  while
 holding  the camera  in  the  harrcl, the  light  shouicl therefore
be bright  sunshine.  On blight  clays snap-shots can be mat'le
 at any  time  during  the  clay from  three  hours  after  suirrise
 to three hours before sulset.  Earlier  or later than this, short
time  exposures should be given.     It  is a goocl rule  ner-er to
photograph  directly  toward  the sun, the best position being
to have the  light  shining from  behind  the operator or over
either shoulder anci clirectly on the object to be photographed,
 If  the  direct rays  of the sun strike  the lens cluring the ex-
posure the picture  rvill be blurred.  Do not trv  to photograph
moving  objects  at  a shortcr  c'listance thal  15 feet  distant
from the camera.   It  is aclvisable to endear.or to catch them
at an angle either coming toward  or goilg  from  the camera,
as goocl results  will   rrot be  obtairred   if  taken  .n4ren the  ob-
ject  is directly  opliosite.   If  photographing  tall  buildings  at
close range  it  is necessarv to secure a position  as near ,as
possible opposite the center of the builcling, for  if  the camera
is  tilted  uprvarci, the  lines  in  the  picture    r-ill  be  fountl  to
converge because of  the  fact  that  the  top  of  the  builtling
is of a much greater  clistance frorn  the ca-era   thair  the  bot--
       This same rule applies .n,hen photographirg  small ob-1o*.

  Whgn  reatly  for  making  the exposure holc1 the camera  in
both hanils and as near levet as plssible so that  the picture
n'ill  be  in  true  perspectir-e.  Locate  the  ob.iect in  the- fintier
by  looking  squa.rely  into    it,  nraking  sure- that   all  of  the
object   rn'hich you  desire  to  photograph   falls   within   the
limits   of  the  fincler.  When   all  is   i-l  ieadiness  release  the

shutter,  taking  care not  to  jerk  or move  the camera during
 the exposure, A pressure of the lever w-i1l open the shutter
 for a fractional  part  of a, second thereby  permitting   the  ligirt
 to pass through the lens anil forming  an irnage on the sensi-
 tive  surface  of  the  film.   After  making  the  exposure  turn
the  'winding  key  to  the  right  watching  the ruby  window   in
the back of the camera until  the next number. appears.  This
is a very important  point and one shoukl early acquire the
habit  of  turning  thc  winiling  key  after  each exposure thus
avoiding the possibility  of making two exposures on the same
surface  of  the  film.
                fime Exposures
  When  making  time  exlosures   it   is  absolutelv necessary
that  the camera be placecl upon  a table  or  other  frm  sup-
port where there nil1 be no clanger of  its being moved tluring
the exposure. Center the  object properly  in  the  finder, and
draw out metal slide (C).  Give a single pressure of the lever
to open, and u.'hen sufficient  time  has elapsed, an  ailditional
pressure to c1ose,using care not  to  jar  the camera in  either
openlng or crosrng.
   fn  making  time  exposures  it   is necessarv to  use sorne
judgment  in  regard  to  the length  of  tirrre the  lens should
remain open.  This is governed br- the amount of light which
falls upon the object  to be photographetl at the time  of the
exposure.
         Time ExposuresOut-of-Doors
  Tn making time exposures out-of-doors the metal slide (C)
shoulcl be dran'n out and the  shutter  opeled and  closeil as
quickly as possible.
  WITH  SUNSHINE   use the  smallest diaphragm, opening
ancl closing the shutter  as quickly  as possible.
  WITH  LIGHT  CLOUDS  use the  smallest  cliaphragm,  giv-
ing from   lz  to one seconcl exposure.
  WITH  HEAVY  CLOUDS  use the  smallest diaphragm  and
gir.e from  2 to 5 seconils.
  The  foregoing   calculations   are  for  open  air  exposures.
When photographing  objects  in shadows or on porches, no
accurate  clirections can be given  as too much depends upon
the  clensity  of  the  shadovvs.         exposure can  only  be

posure meter  such as the  Watkins  Bee.
  CAUTION.    Ner.er attempt  to make a time exoosure while
holrling the camera in  tlre hand as a blurred picture is sule
to result.

             Removing the Film
  No  rlark room  is requiretl  for  removing  the  fiIm from  the

      It  will be noted that  the negatives are of different  density.
This, horvever, is not an objection as this can be overcorn:  i.n

be watched  by  holding  the  strip  up  to  the  larnp from  time
to  time.     It  rs advisable, horvever, to make  the examination
as short as nossible.                'Io    Note:       avoid transparent  spots after  having passed the

and dlarving   it  lightly  through  the developer under the hand.
This   ll,'ill brcak   ail  the  air  bubbles.  Tlansparent   spots are
causcd by  air bubbles adhering to the film  rluring do'elopment.
    After  the development  has been completecl, pass the  film
a  fe'rv times  through  the  clear  rvater, thcn  transferring     it  to
the tray  containing  the  flxing  bath.  When  al1 of the creamy
surface hns disappeared from  the  unsensitizctl  surface  of  lhe
film  fixation  is practically  complete.    It  is, horrever, advisable
to  continue  to  pass  the  film  through  the  solution  trvo  or
three  minutes  after  the  disappearancc  of  the  creamy  color.
    After  the films are thoroughly  fixed they should be washed
in  colrl mnning   r.ater  florn  forty   to  sixty  minutes.     If  run-
ning water  is not convenient, tcn changes of lresh water should
                                              -   t z -

be used, keeping the  fllms constantly   in motion  all the  I'hile.
The thorough  lvashing  of the films  is very  important   in order
to remove  all  traces  of  the Hypo  or  else stains   'lvill appear
after  drying  and the negatives   rvill be ruined,
    After  washing, the films should be hung up to dry  in such
a manner  that   it does not touch the surrounding  objects.  The
place selected for  drying  should be free from  dust.    If  a mild
current  of  air  is present the process of drying   rvill be greatly
quickenecl.
   The temperature   of  the  developing  solution  should be as
near as possible to 65 degrees Fahrenheit.  The  fixing  bath
and  water  used  for  rvashing  should be kept  cold,  ice being
employed in extremely  hot l-eather.





         Cutting the Film for Separate Development-Figure 9
   The use of f,he Ingento Developing Roller  rvill greatly  facil-
itate  the developing process.  This  device consists of a heavy
glass  roller  lvhich  revolves  on  trvo  brass  pins  mounted   in
extra  heavy  nickel  plated  brass  frame.    Its  ot'n  rveight  is
sufficient  to resist thc ^Whenoull  of the film when   it  is being drarvn

solution  ordinarily  required  need be made  up, as the  roller
over which  the  film  is drawn  is within  3/16  of an inch from

 nierged  in  less than  one-half  inch  of  solution.     It   is  for  use
 in trays  4x5 or larger and  rvill accommodate any  film  4lax61/2
 or smaller and can be obtained from  all photo supply  dealers.

     'Ihe        above directions  apply  to the developmerrt of the  film
 in the strip.    It  is sornetirnes advisable to develop each section
 separately,  especially lshere there has been a great  variation
 in the exposures given.   In  this case the following  directions     !

in the  tray  containing  the dcveloper;  rock  the  tray  gent)y  to     I
prcvent  strealis  and  air  bubblcs.   In  about  one minute  the  €
film  will  begin  to darken, representing  the high  lights  of the  C
picture, and  in about two  minutes  the image  v'ill  be discern-  V
ible.  The common  'way  of  determining  rvhen  the  fiim  has E
been fully  developed is to look on the back to ascertain whether  F
the obiects in the picture have begun to show through.  When
developing  films  singly,  from  five  to  six  minutes   is  usually
required,  the  time  varying  according  to  the  temperature   of
the  solution.
   When  development   is  complete  transfer  the  film  to  the
tray  containing  clear  rvater  ancl rinse   it  trvo  or three  trmes,
after  rvhich   it  should be  placeil  in  the  tray  containing  the
fixing  bath.   At  this  juncture  the second section  of  the  film
shoulal be  put  through  the same process, care having  been
                           _   t 4 _

taken  that none of the Hypo has adhereil to the fingers, thus
allowing   rt  to come rn contact  with  the undeveloped section
 of the tilm  or with  the developer.
    Three  or more  negatrr-es may  be developed  at  one time
by  placing  the  films  in  the  dcveloper  face dorvn and  alter-
nating each section so as to prer-ent air bubbles; however, r,ve
recommend  that  the beginner  devclop  only  one section  at  a
time  until  the neccssary experience has been gained.  As each
successive section  is developed and  lixed   it  shoulcl be placed
in the rvashing  rvater.   After  the  films have been thoroughly
rvashed they should be pinned up separateiy  to dry, care being
taken  that   their  surface  is not  allos'ed  to come  in  contact
rvith  the surrounding  objects.

               Making Prints
   There  are  in  general use, three  classes of paper used for
making  pictures;  namely,  blue  print  or  ferro-prussiate  paper,
printing-out   paper such as  Solio, Disco,  etc., and  developing
or gaslight  paper, such as Rexo, Velox,  Argo,  etc.  The  first
two  classes are  for  daylight   printing   only,  .while  the  last
c.lass may be printecl either  in subduetl daylight  or by  arti-
ficial Jight.
               Printing-Out Papers
   Open the  printing  frame and place the negative  face down
upon  the  glass, then  place upon  this  a sheet  of  blue  print
paper.  Replace the back  of the  printing  frame  and secure  it
with  the springs.    It  rvill be noted that  the back of the  print-
ing frame  is hinged so that  a part  of the  print may be uncov-
                            _   l 5 _

                       www.orphancameras.com

eled  for  inspection  during   printing,   without   disturbing    its
 register  with  the negative.  The loading  of the paper into  the
frame  should be done in a subdued  light,  that   is, in an  ordi-
nary  room,  but  as  far  as possible from  the  window.   The
unuged paper should be returned  to  its package for  protection
from  the  light.
   The  loadecl printing  frame  should be placed glass side up
in the strongest  possible light,  direct  sunlight  being preferred.
 It  is allowed to remain  until  the image from  the negative has
been sufficiently  impressed on the  sensitive  paper.  This  can
only be determined by an occasional examination  of the paper.
Print  until  the shado'lvs become a gray bronze color, or  until
the high  lights are slightly  tinged with  blue.  When  this stage
has been reached remove the  print  from  the  printing  frame,
wash thoroughly   in running  water  for  15 rninutes  or  in  sev-
eral changes of  cold  water,  allorving  the  print  to remain  in
each bath  a  ferv minutes.   After  having  thoroughly  washed
the  print  as above inclicatcd,  it  should be hung up  for  drying.
The  Ingento  Blue  Print  Paper  is  especially recommended as
 it  is prepared  especially  for  photographic  purposes.
  'When          using a printing-out  paper such as Disco, Solio, etc.,
the frame  should be loacled as directed above  for  blue  print
paper.  The  printing  should be allorved to continue  until  the
tone of the  print  is somewhat  darker  than  is desirable  in thc
finished picture.  Ingento Toning and Fixing  Solution  is highly
recommenried for  toning  this  class of  p:rper.   I{ix  the  toning
solution  as dirccted on the package and pour   it  into  a  tray.
The  prints  shoulil be immersed  in  this  solution  face dorvn so
as to  insure  the even action  of  the  solution  over the  rvhole
surface  of  the  print.   After  a moment  or  so, the  print  may
be reversed so that  the  toning  can be watched.  Repeat  this
process from  time  to  time  during  toning.   Thc  prints   will
begin  to  change  color  immediately  qpon  immersion   in  the
toning  bath.   At   first  they  are of a reddish brown,  changing
gradually  to reddish yellolv, then to brol'n  and then to purple.
Toning  should be stopped when  the  desired  shatle has been
obtained.   At  this  point  the  prints  should be transferred   to
a salt  solution made by  dissoh'ing one tablespoonful  of com-
mon  table  salt  in 16 ounccs of  v'ater.  The  prints  should be
                           _ 1 6 _

allowed  to  remain   in  this  solution  about  5  minutes,  after
 which  they  shouid be rvashed for one hour  in running  water
 or in twelve changes of water.  They are then ready foidrying,
 books and  for  this  purpose  \.\.'e recommend  Ingento  Blatter
 Several  prints can be toned simultaueouslr..
         Developing on Gaslight Papers
    Developing  Papers, such as Rexo.  \-elox,  -{rgo,  etc., are
 very popular  with  arnateurs because of the  simplicity   in  their
 operation,  the excellent rcsults  obtained and the added advan-
 tage  of  being  able  to  print  thern by  artificial   light.   These
 papers can be hanclled  rvith  safety  eight  or  ten  feet away
 from  an  ordinarv   gaslight.   Thcy  should  not,  however,  be
allou-cd  to remain  uncoveled  in  the  direct  rays  of  the  iight
even  at  this  distance  for  any  considerable  time.  The paper
 is  loadcti  into  an  orclinary  printing  frame  in  the same man-
ner  as aboye  desclibed  for  printing.out   papers, taking  care
 that  the emulsion  side of  the paper  is against  the  dull  side
of  the  film.   The  emulsion  side  of  the  paper can be  deter-
rnined by  tendency  of  the  1,3pp1 to  curil  in  that  direction,
or by  biting  a corner  of  the papcr, the emulsion  side tending
to  sticl< to the teeth.   \Iith   the back of the frame clamped in
position,  it  is exposed by holding  it  near a gas jet, lamp  or
incandcscent  light.  The length  of the exposure depends upon
the  distance  at  r.vhich the frame  is held from  the  light,  and
the density  of the negative.  Erposure can also be rnade in
subdued daylight;   hou,ever, artificial   light   is  preferred, as  it
docs not vary  in  intensity  as  is the case rrith  daylight  and
it  is therefore much easicr to judge the length  of the exposure
recluircd,
    \Tith   this  class of paper no image  is seen on the  surface,
until  the  print  has bcen placed in the deleloper.     'l'he         larger  the negative, the greatcr  the distance  it  should
be hcld from  the  light,  the usual  rule being  that  the  proper
distance  is equal to the diagonal  of the negative.  The time  of
exposlrre varies  with  the  distance the  printing  frarne  is held
flom   thc   light.      If,  horvo.er,  daylight    is  used,   it   rvill  be
found  advantageous  to cover  all  the  s'indorvs  with  postoflice
paper, 'lvith the exception of an opening about one foot square.
Ovcr  this  opcning  ts.o  or thtee  sheets of  tissue paper should
be pasted to  diffuse the  light,  thcn use a piece of blacl< cloth

or any  other opaque medium  to cover  this opening when  the
rvhite  light  is not  desired for  printing  purposes.   In  this case
the  frame  should be held from  one to  trvo  feet away  from
the opening  during  exposrrre.   It  is imptssible   to  E;ive exact
directions as to the length  of exposure ori account of the great
difference  in  the  intensity   of  daylight   at  various  times,  the
best method  being  to make  test  exposures  'lvith  small  strips
of the paper used.

rn from  eight  to  ten  seconds.   It   lsill  rapidly  gather  detail

should be quickly  rcmoved  from  the dcveloper and placed in
