Improvements in Printing Artificial Skies by Photography on to
Photographs.
I GEORGE JOSEPH SERSHALL of 371 Lodge Road Hockley Birmingham in the
County of Warwick Artist do hereby declare the nature of this invention to be as
follows:-
A drawing is made of a portion of a Sky upon stone paper zinc wood copper glass
or any other suitable material for printing from either by letter press, lithographic
copper-plate zincographic or any other suitable printing method, from which impres-
sions are printed on to paper gelatine glass or any other suitable material already
transparent, or to be made transparent after printing by varnishing or other means.
Then a photographic negative being taken of a Landscape or View, the part representing
the Sky is stopped out or rendered opaque. A photographic print is then taken
from the unstopped portion of the negative on sensitized silver paper from which the
blank portion corresponding with the stopped out sky in the negative is carefully cut
off to the edge or the Landscape or View. This sensitized paper in this condition is
next exposed to day light and allowed to become black, and is afterwards used as a
mask in the process of photographic printing in accordance with this Invention.
With the said transparency representing a Sky, the said partly stopped out photo-
grapic negative, and the said mask, all prepared as described, the process of
protographic printing is as next follows. A sheet of sensitized paper is placed in
contact with the aforesaid negative and the unstopped portion of it printed in the
ordinary photographic manner, and on this operation being completed, both are
removed from the printing frame, and a sheet of clean glass of a suitable size placed
therein. Upon this glass the transparency representing Sky is next placed and then
that portion of the sensitized paper upon which the Landscape or View has been
printed and is to be retained is carefully protected and accurately covered by the
blackened mask and both in this condition placed upon the said transparency
intervening between them and the clear sheet of glass. All these then being
properly exposed to light the picture including the sky will be printed and
completed.

Improvements in Printing Artificial Skies by Photography on to
Photographs.
I GEORGE JOSEPH SERSHALL of 371 Lodge Road Hockley Birmingham in the
County of Warwick Artist do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
--
A drawing is made of a portion of a Sky upon stone paper zinc wood copper glass
or any other suitable material for printing from either by letter press lithographic
copper plate zincographic or any other suitable printing method, from which impres-
sions are printed on to paper gelatine glass or any other suitable material already
transparent, or to be made transparent after printing by varnishing or other incans.
Then a photographic negative being taken of a Landscape or View, the part repre-
senting the Sky is stopped out or rendered opaque. A photographic print is then
taken from the unstopped portion of the negative on sensitized silver paper from
which the blank portion corresponding with the stopped out Sky in the negative is
carefully cut off to the edge of the Landscape or View. This sensitized paper in this
condition is next exposed to day light and allowed to become black, and is afterwards
used as a mask in the process of photographic printing in accordance with this
Invention. With the said transparency representing a Sky, the said partly stopped
out photographic negative, and the said mask, all prepared as described, the process
of photographic printing is as next follows. A sheet of sensitized paper is placed
in contact with the aforesaid negative and the unstopped portion of it printed in the
ordinary photographic manner, and on this operation being completed, both are
removed from the printing frame, and a sheet of clean glass of a suitable size placed
thereon. Upon this glass the transparency representing Sky is next placed and
then that portion of the sensitized paper upon which the Landscape or View has been
printed and is to be retained is carefully protected and accurately covered by the
blackened mask and both in this condition placed upon the said transparency inter-
vening between them and the clear sheet of glass. All these then being properly
exposed to light the picture including the Sky will be printed and completed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
In the process of printing artificial Skies in photography, the mode of producing
and of using the transparency representing a Sky, the partly stopped out negative,
and the photographic mask as herein described.
Dated this Seventh day of November 1887.
