BROMIDE PAPER
Bromide Paper is a pure photographic paper coated with
a.. se'sitiv.e qompound, compoied rrriniipallv bt nromiae or
srlver and- white gelatine and similar to the emulsion of the o.rdrnary dry plate.or film, only of much less rapidity, permit_

of pap'er some distance apart instead of in contact, as in mak-
ing an ordinary print, a clearer understanding of the process
will be afforded.
Bromide paper has remarkable keeping qualities both be-
fore and after exposure, and the developed print when care-
fully fixed and washed is as permauent as the paper support
itsel f.
WHAT IS AN ENLARGEMENT ?
An enlargement, in the usual sense, is a positive image or
picture obtained by permitting rays of light to pass through a
negative, then through a lens and focusing on a sheet of ien-
sitive bromide paper; the size of the projected image depend-
ing upon the distance between lens and sheet, the further the
sheet is from the lens the greater the enlargement, which will
be readily understood by reference to cliagram on page 5.
An enlarged negative can also be made in the same man-
ner by using a small positive, the projected image focusing
on a dry plate instead of on bromide paper.
UTILTZING THE KODAK AND BROWNIE
FOR ENLARGING I
Most of the present rnodels of the Kodak and Brownie
can be utilized for enlarging, excepting only tl-rose models not
permitting the removal of the back and the racking back ancl
forth of the lens.
The use of Kodaks such as the No. 2 and No. 3 Bulls-
Eye, the No. 1, No. 2, 2A and No. 3 Brownie, for enlarging
is lirnited, as the distance between the focal plane and the lens
is fixed and prevents the making of enlargements beyond a
certain size. The folding Kodaks (except the No. 1 and No.
I1A) and the Cartridge Kodaks, including the Screen Focus
tKodak, lend themselves particularly well to enlarging.
The method of utilizing these instruments is shown in the *.1

The Shutter to exclude light from the window, and to

where the frame is attached, the remainder of the window
may be blocked up with heavy press board or opaque cloth.
This will lessen the expense and also facilitate the putting in
place and removal of the frame.

In many instances the actual picture is contained in a
comparatively small portion of the negative, and in such cases
aall unused portions of the negative may be covered with
rnask of post office or black paper.
If any light enters from between the l(odak and the hold-
ing fram-e ii rnay be excluded by throwing an opaque cloth
over the frame.
The Cartridge Kodaks and the Screen Focus Kodak may
be utilized in practically the same manner as will appear by
referring to Fig. 4. The Kodak is easily held firmlv in place
as shown in the diagram.
Any Plate Camera of the so-called cycle type may be used
for enlarging by making use of the holding frame.
The negative in such cases is best secured in position by
utilizing atr1ld plate holder with the center septum and dark
slides rlmoved, insert the negative in the plate holcler up side
down and with the du1l side toward the lens, placing the
holder in the back of the camera in the usual manller'
If ground glass in the back of the camera intercepts too
much light it should be removed.
Unless the window you intend to use commands an un-
obstructed view of the horizon, a piece of heavy wltite card-
board about 15 inches long and 12 inches wide or larger
should be placed just outsitle the window at an atrgle 45" to
reflect the light from the sky. (See Fig. 2.)
To ascertain if the reflector is in the proper position place
a sheet of ground glass over the opening in the holding frame.
If properly placed the ground glass will be evenly illuminated.
No hirm-w:ill result if the sun shines on the ground glass
and reflector, provided it strikes evenly; if the light is too
strong the lens can be stopped down.
. The easel or copy-board for holding the Bromide paper
may be constructed as shown in Fig. 3, or it may be modified
to suit individual needs or conditions.
In cases where the window is some distance from the
floor. or the window surface is exceedingly large, the Kodak
holdine frame may be placed directly on the lower sill and
the light excluded by covering the balance of the window as

previously suggested. The whole apparatus is so exceedingly
simple that modifications to suit individual requirements can
easilvtr
3Tr? be observed to' keeil the easel front exactly
parallel with the negative.
The best negative for enlarging from is one not too dense
I or too weak but with good detail in tl-re shadows and trans-
parent in the high lights.
I
THE SIZE OF THE ENLARGEMENT
t! depends upon the focus of the lens and the distance of the
easel or copy-board from the negative.
Even when using the No. 44 F olding Kodak with its lens
of 8l inch equivalent focus, a six times enlargement will only
require a distance of five feet from the lens to the Bromide
paper, so it will be seen that only a small space is necessary
for all ordinary requirements.
THE LENS
Any lens that will make a good negative may be used for
enlarging. The proper size (focal length) of the lens depends
entirely upon the size of the negative to be enlarged from and
not at all upon the size of the enlargement to be macle.
The lens that made the negative will be suitable for en-
larging from that negative. If the lens will cover the nega-
tive it will make an enlargement from it of any size. Any
I Kodak lens is suitable for enlarging from negatives made with
the Kodak to which it is fitted.
I I MAKING. THE EXPOSURE
Having placed the negative in position, and taking care
. that the package of bromide paper is well protected, set the
shutter for time and press the release to open same, an image
more or less blurred will appear on the easel, trow move the
easel back and forth until the desired size of the enlargetneut
is secured, then focus the image sharply by racking the lens
back and forth.
The nearer the lens is placed to the negative the greaterView original page 14Page 15 · Read text
t2 EASTMAN KODAK COMPANY
the size of the enlargement and the copy-board will have to
be moved back correspondingly to obtain sharp focus.
Focus with the lens fully opened, then stop down to at
least stop .16. This not only insures good definition but by
lengthening the time of exposure permits greater control dur-
ing exposure, affording time to shade or locally increase the
exposure- on any portion of the image. After having obtained the desired size and correct focus
close the shutter-bnd place the sheet of Bromide paper in posi-
tion on the easel or copy-board. Before capping the lens or
closing the shutter the correct position for placing the sheet
of Bromide paper should be marked on the copy-board.
A'deep colored ray screen may be utilized as a lens cap,
as the light corning through this screen will not affect the Bro-
mide paper for a few minutes, and the operator can by this
means see just where to fasten the sheet of Bromide. It is per-
haps unnecessary to state that the coated or emulsion side of
the paper should be out. (The coated side is slightly concave.)
Before opening the package of Bromide paper see that no
white light enters the room. It is well to provide a good sized
box with a hinged light tight cover to keep the Bromide paper
in until needed, with also a compartment to hold the exposed
sheets when making a number of enlargements to be devel-
oped later
TEST EXPOSURES
After the correct size and focus has been obtained the
next step is the exposure.
Provision should have been made for a non-actinic yellow
or orange dark-room lamp, or a small window opening outside
covered with several thicknesses of yellow or post office paper.
In first attempting the making of enlargements, test strips
for determining the accuracy of focus and proper duration of
the exposure should be employed.
A strip one or two inches wide and long enough to extend
diagonally across the focused image will be sufficient.
Correct exposure depends on several factors; the inten-
sity of the light, density of the negative, size of the enlarge-
ment, and aperture of the lens.

The first test exposure will be purely arbitrary; if the light

' In shading any portion during exposure, hold the shade
nearer the lens than the copy-board to avoid sharp lines and
obtain the proper diffusion.
DEVELOPMENT
' After the exposure has been made the next step is de-
velopment, which is accomplished in practically the same
manner as in the development of a plate or film.
Provide a ruby or orange lamp, graduate, stirring rod and
three trays, preferably of hard rubber or rubber lined, at least
an inch larger each way than your sheets of Bromide paper, to
facilitate handling.
A rubber lined tray of any size is easily constructed by
glueing a sheet of gossamer rubber cloth into a wooden box
or tray.
As the Bromide paper is not as sensitive to light as a dry
plate or film a somewhat stronger liglit may be employed for
developing. A small window opening outside, covered with
two thicknesses of yellow post office paper will serve, or the
ruby.glass may be removed from the dark-room lamp. The
remaining orange glass will be ample protection against fog
and allow the process of developrnent to be observed with
greater ease.
Use developer at a temperature of about 70o Fahr., witl-r
Nepera Solution 1 to 6 at 70' temperature, the image should
appear in from 72 to tS seconds and the print allowed to de-
velop for at least 1 minute to ll minutes. If the prints de-
velop in less than one miuute under the above conditions, the
exposure has been too long. If the print is not fully developed
in l/z minutes under the above conditions,. the exposure has \l
been too short.
After development is complete the print should be rinsed iin clean water for a few seconds and then immersed in the
fixing bath. Do not attempt to develop too many prints in
one portion of developer (see page 15).
There are a number of clevelopers that will produce good
results on Bromide papers, when used by experienced hands,
understanding their limitations. The professional photog-
rapher enlarges from a uniform quality of negative and for a

certain effect: on the other hand, the amateur from the wide
diversity of his attempts, finds his negatives varying in den-
sity and quality, and the best developer for him to use is the
one affording the greatest latitude in exposure and develop-
ment, and one that keeps well in solution.

MOUNTING
A very satisfactory way for mounting small etrlargements,
not larger than 6l x8l, (above that size they are best
mounted wet with a good starch paste as a Kodak Dry Mount-
ing Press would be necessary with the tissue in the iarge sizesand this, of course, the amateur would.not be likely to have t
in his equipment), is by the use of Kodak Dry Mounting
Tissue, as the print lies absolutely flat in perfect contact, even {on the thinnest mount and without curl.
The tissue comes in flat sheets, dry, not sticky, is easy to Jhandle and the tissue being water proof protects the print
from any impurities in the mount stock.
For multiple mounting and folders the tissue is an ideal
mountant. The process of mounting is as follows:
Lay the print on its face and tack to the back a piece of
the tissue of the same size, by applying the point of a hot
flatiron to small spots at opposite ends.
Turn the print face up and trim print and tissue to the
desired size.
Place in correct position on mount, cover print with a
piece of smooth paper and press the whole surface with a hot
flatiron. Prcss, don't rwb.
The iron should be just hot enough to siss when touched
with the wet finger. If the iron is too hot tissue will stick
to the mount and not to the print: if too cold the tissue will
stick to the print and not to the mount.
Remedy: Lower or raise the temperature of the iron and
apply again. To mount with paste proceed as follows: I
On Card-Bromide prints may be mounted rvet. Lay Jthe wet print face down on table covered rvith oil or rubber
cloth or sheet of glass and squeegee off all the surplus water,
then brush over the back with thin starch paste, lay the print
on the mouut, then cover the print with a clean sheet of paper,
and press into contact with squeegee or rubber print roller.
Straightening Unmounted Prints-After drying, prints
may be straightened by the scraping action of a sharp edged
ruler applied to the back; the corner behind the ruler being
lifted as the ruler is passecl along.

WHAT PAPER TO USE
Eastman Permanent Bromide papers, since their intro-
duction twenty years ago, have been considered standard by
the photographic public, and testimony as to their superiority
is constantly being recorded.
The list ancl description of the various kinds of Eastman
Bromide paper and statement of use to which each is best
adapted, is as follows:
Velvet Bromide: Suited to negatives having broad
shadows, the s-light sheen of the semi-gloss surface glving to
enlirg'ements from such negatives a life and briliian-y r-hich
is highly pleasing. Velvet Bromide is especially appreciated
by those who enlarge from amateur or landscape negatives.
Brilliant Velvet Bromide-A paper similar to Veivet
Bromide, but with more contrast, and therefore especially
suited to the average amateur negative, or where moie con-
trast is desired in the print.
Standard Bromide Paper-is a natural surface bro-
mide paper, which is especially adapted to all kinds of enlarge-
ments, particularly copies on which crayon or pastel work is
to be done.
The emulsion is coated on three different weights of paper
thin smooth-B, heavy smooth-C, heavy rough.-A,View original page 20Page 21 · Read text

BROMIDE ENLARGING WITH A KODAK 21
Royal Bromide is not inter-rded for use when vignetted
prints with white backgrounds are wanted, as it is coated on
paper having a delicate cream tint, the yellowish cast in high
lights harmonizing beautifully with dark backgrounds.
Silk bolting cloth helps to produce the general artistic
$ effect by increasing the softness and breadth. Made in two surfaces, rough and smooth.
t SPECIAL EFFECTS 17d,4'*.'-1
I* Pictures of beautiful softness ancl breadth can be made on
Royal Bromide by ma.king the enlargement through a screen
of silk bolting cloth.
The screen softens the heavy mass of the shadows and
blends them in harmony with the higher tones.
The most convenient way to use the bolting cloth is to
stretch it over a frame or strainer. If the screen be used in
direct contact with the paper, the enlargement has the effect of
being made on fine meshed canvas.
To secure greater diffusion place the screen at a distance
of. r/a inch to one inch from the paper.
The further the screen is removed the greater the dif-
fusion of light.
The use of the screen increases the exposure about one-
third. Focusing should be clone before the screen is put in
place. With srnooth paper the fine mesh bolting cloth should
be used. With rough paper use either the medium or coarse
mesh. For small prints use fine mesh. For the convenience
of our customers we have arranged to furnish the best quality
of silk bolting cloth and will ship same in rolls, thus avoiding{{,* all folds or creases in the cloth.
SEPIA TONES ON EASTMAN BROMIDE
PAPERS
Of the several processes for securing sepia tones in
Bromide prints, we give preference to the method of re-
developing ancl the use of Royal Re-developer. The results
secured with Royal Re-developer are chemically identical withView original page 22Page 23 · Read text
EASTMAN KODAK COMPANY
those obtained by the Hypo-Alum method, and there can be
no question of permanency as there is no change, except in
the color of the print, either in detail or gradation. The ex-
pense of the process is slight, as three hundred 8 x l0 prints or
their equivalent can be re-developed with the contents of a
75-cent package of Royal Re-developer, and the time involved
is considerably less than required when using the cold Hypo-
Alum tor-ring process.
A Bromide print of any texture of surface, which, wherr
made, was eaenly fired and thorough,ly washcd,, will give a
desirable result when Re-Developed. d
Some additional features of Roval Re-DeveloDer are as i.,I follows: I
Uniformity-Following the directions given herewith will ..t.l
insure absolute uniformity. r
Rapidity-A Bromide print can be turned Sepia in less I
than two minutes' time.
TO PREPARE SOLUTIO,NS tll
To prepare bleaching bath dissolve contents of tube ft
marked "Bleaching Agent" in 20 ounces of water.
To prepare re-developing solution, clissolve the contents I*
of a tube from the carton marked "Re-Develooer" in 32
ounces of water.
DIRECTIONS
l--Immerse print in bleaching bath, letting it remain until tI only faint traces of the half-tones are left and the black of
the shadows has disappeared. This operation will take about
one minute, though no harm will result from a somewhat *lt longer imrnersion.
2-Rinse thoroughly in clean cold water until no yellow-
ness remains in wash water.
3-Place in re-developing solution until original detail
returns. (About thirty seconds.) Prints should be rinsed
thoroughly, then immerse same for five rninutes in the follow-
ing hardening solution:
Water, 16 ozs, Velox Liquid Hardener,
4-Wash for half an hour in running water.

. CONTACT PRINTING
Eastman Bromide Papers may be used for contact print-
ing by either artificial or dayligl-rt, but we would recommend
for this purpose Velox paper, as that is manufactured espe-
cially for such purpose.
Eastman Bromide Paper is very sensitive. It cannot be
hancllecl in an ordinary light and the printir-rg frame must be
loaded and the unexposerl paper handled or-rly by yellow or
orange light.
For daylight about two thicknesses of yellow post office
paper over the dark-room window would be safe or one thick-
ness when working by gas or kerosetre.
The exposure varies with the intensity of the negative
and quality and intensity of the light. An average negative
would require approximately one-quarter second by daylight
or ten seconds at a distance of one foot from a number 2
kerosene burner.
ENLARGING. ON VELOX
Special Velox, instead of Brornide paper, may be em-
ployed for making enlargements, but we do not recommentl
it for daylight enlarging except in cases where the r-regative
-can receive the full light from the sky.
fn cases where the light is reflected upon the negative,
Velox is not of sufficient rapidity to prove of practical value.
While Velox entails a very much longer exposure to the
light (about sixty times) than Bromide paper, it possesses thc
great advantage of being handled in a much stronger light
and does away entirely with the dark-room for any of the
operations. The contrast of Velox makes it specially well
adapted for enlarging from small, weak negatives and a great
latitude in exposure and development enables the amateur
with but little experimenting to secure first-class results.
When using Velox, there is of course, no difference in the
method of loading the camera from that when using Bromide
paper, except that no dark-room is necessary; the window
shades should, however, be pulled down and the paper
hanclled in a corner of the room farthest from the outside
light.View original page 24From the M. Butkus archive. Original publisher and archive notices are retained.
