ENHANCING NEGATIVES.
Any One Can Make Pictures From
Little snapshot Photographs.
BY Raymond Ball.

One of the many ways in which a camera
may be utilized when the winter weather
makes 1t unpleasant to be out of doors,
and the making of interior flashlights be-
gins to grow monotonous, IL the enlarge
ment of some of those pretty exposures
made during The summer.
This can be done with any make Of cam
era, having a detachable back, and the
only thing In the way of special apparatus
necessary is a couple of large trays for de-
veloping. together with a sufficient sup
ply of bromide paper.
1t Is assumed that the reader has mas
tered the rudiments of photography Is ia
miliar with the chemical action of light
and can develop negative creditaoly
well. A small room having a window fac
ing the north, through which the light Is
admitted, unobstructed by trees or other
objects is required to work in All light
should be excluded from the room by
means of a covering for the window Of
heavy, dark paper. In the ceErer os this
covering an opening must be made some
what smaller than the negative to be en-
larged from. One side of a narrow strip
of the dark paper should be fastened both
above and below the opening in the window
covering, so that the unfastened sides are
toward the opening. These strips are for
purpose of holding the negative.
In case the room does not have a window
through which the light from the sky
is admitted direct a mirror about three
feet long should be placed outside of the
window at an angle of As degrees so as
10 reflect the light on the window cover
ing.
The negative, If film, should be placed
in the prepared position, with a piece Of
ground glass at the back, and a piece of
plain glass between il and the camera.
The image on the negative should be up
side down. Next remove the back Of the
camera, including the ground glass, etc,
and place 1t in position on a table with
the back TO the opening, so that IL covers
the negative.
An ordinary drawing board strapped or
otherwise fastened to a box will answer
for a support for the sensitive paper dur
ing the exposure. After covering the sup
port with a piece of white paper, place IL
on the table then, open the shutter of the
camera as directed for time exposures
The Image Of the negative will then be
projected upon the paper.
The support will have TO be moved either
way until the size of the desired enlarge
ment is obtained. and the focusing done
on the plain sheet Of paper by using the
focusing arrangement Of the camera. Use
the largest stop for focusing, but before
the exposure, substitute smaller one
according to the light. Care should be
taken that the only light 10 enter the
room should be that passing through the
negative and through the lens of the cam
era.
Before the final exposure Is made, 1t
would be well to make a test upon a strip
Of sensitive paper for the purpose of de-
terniuing the correct length of exposure.
Place the strip diagonally across the To-
cused image. Cover all but a fourth of
the strip, open the shutter and give an
exposure of half a minute. then uncover
another fourth and give another half min
utes exposure. Repeat this until the re-
naming two-fourihs have been exposed.
and then develop The first fourth Will
have been exposed two minutes, the Sec
one and a half; the third, one; and the
fourth, thirty seconds. When the develop
ing has been finished il will be seen which
Of these Is correct.
Now pin a piece of the sensitive paper
of the required size upon the drawing
board, being careful to have II lie perfect
~ fat. Everything is now ready for the
exposure. open the shutter and give Il
the correct length of time, which has been
ascertained by the test.
The developing process is much the
some as that followed in the development
