FABRIC PHOTOGRAPHY

Inquiries are repeatedly made for q
process or means whereby prints can
be made upon good cotton fabric such
as sateen, or like material, as well as
upon paIier and celluloid, by exposure
to gaslight or any light of moderate
intensity and developed with one of the
modern developers. Although prints
of a kind can be made upon such ma
terial with a slow bromide emulsion,
finer results by far can be made with
a chloride emulsion prepared as here
described, the deposited silver being or
an intense black in the deepest shadows,
while the half tones are we'll rendered
and the whites very pure, writes "A. u.
Garman in American Photography.
Any one who will take the trouble to
prepare the emulsion will be amply re
warded for their time and effort. The
material used in the line of fabric must
be white sateen. that has been well
washed in several changes of clean,
hot water, then Wrung out, Stretcheu
and dried. then flattened by carefully
ironing with a very clean tlatiron. Ihe
paper used must be of good quallty,
the same as is used for the making OF
gaslight developing papers. Stein
bach's. which can be bought at any art
store, will answer the purpose, as Will
clean white matt surfaced celluloid,
the surface being cleaned with a tuft
of absorbent cotton and hot water,
then dried before use.
Making the emulsion: Procure a
clean half gallon crock, place therein,
cut into strips, the following:
Heinrichs hard gelatine ...........'''' ounces ounces
Distilled water ......................... ounces
Chloride of ammonium ...............'of grains
Place this crock into a vessel of hot

gelatine mixture we'll With glass rod,
then add the following:

Citric acid (crystas) ..............''' ~ grains
Stir we'll until dissolved add this to
the gelatine solution, under ruby
light, a little at a time, stirring Wen
during this addition. This mixture
must now be stood aside in a cool place
to set, or it may be stood in ice water
to hasten the setting. When quite cold
and well set, it must be wrung through
a piece of well washed coarse canvas
by placing some pieces cut from the
mass into the middle of the canvas,
then by bringing the corners OF the
canvas together, holding the middle
firmly in the left hand, then twisting
the canvas with considerable stfalh'

then wrap the canvas doubled over the

seven times in like manner with very
cold. clean water, making the hnal
wash with distilled water. The last
draining must be thorough. Remove
the canvas, wipe the top of the crock
clean and add two ounces of pure alco-
hol. (Use no wood alcohol, or dena-
