Composite Portraiture
235
C is a travelling carriage that supports the portraits in turn, from which the composite
has to be made. I work directly from the original negatives with transmitted light; but
prints
A the body of the camera, which is fixed.
B Lens on a carriage, which can be moved to and fro.
c Frame for the transparency, on a carriage that also
supports the lantern; the whole can be moved to and
fro.
r The reflector inside the camera.
m The arm outside the camera attached to the axis of
the reflector; by moving it, the reflector can be moved
up or down.
g A ground-glass screen on the roof, which receives
the image when the reflector is turned down, as in the
diagram.
e The eye-hole through which the image is viewed
on g; a thin piece of glass immediately below e,
reflects the illuminated fiducial lines in the
transparency at f, and gives them the appearance of
lying upon g,—the distances f e and g c being
made equal, the angle f e g being made a right
angle, and the plane of the thin piece of glass being
made to bisect f e g.
f Framework, adjustable, holding the transparency
with the fiducial lines on it.
t Framework, adjustable, holding the transparency
of the portrait.
