PRODUCTION OF ,DESIGNS, ESPECIALLY SCENE} EFFECTS AND IN APPARATUS THEREFOR.
Application filed June 4, 1924, Serial No. 717,706, and in Great Britain September 21, 1923. i
This invention relates to the determination of the colours or shades to be employed 1n the production of coloured pictures or designs of posters, cretonnes and the like and also to the production of designs particularly scenic effects and in the determination of the colours or shades to be employed in the scenic eiiects- According to this invention a number of photographic negatives is taken of the picture or design preferably on one plate, each negative representing such parts of the picture or design as are to be coloured or shaded the same, the rest of the picture or design being stopped out in each case. Positive transparencies are made preferably on one plate from the negatives and are placed in projecting apparatus by which they are proj ected on to a screen to produce thereon the picture or design. Y
Difl'erent colour screens anddifferent luminosities are employed with each positive screen. When the most satisfactory colour or shade efiect has been found the colour of the screen or the amount of luminosity employed with each positive is noted and this colour and luminosity is employed in the production of the icture or design. Y
When the invention is applied to the pro duction of scenic effects a scene to a small scale is constructed and a number of photo- .7 graphic negatives are taken on one plate or sheet in a camera of the scene, each'negatwe.
representing part of the scene, the rest of the scene belng stopped out 1n each case. Positive transparencles of a larger size are made from the negatives, the positives be-.
ing rinted on one plate or sheet. The positives are placed in of a larger s ze than t and are projected'in the theatre itself. The ratio of the size of the negatives to the 1mmtives should be equal to the ratio of the focal lengths of the lenses of thercamera and the projector.
In projecting the parts of the picture the colour screensused for each part may be varied as desired and the intensity of-the light used with each part may be varied so varying the shades whether colour screens, neutral screens or no screens are employed.
projecting apparatus e camera employed,
of which may be arranged in a circle with three arranged round its centre and in rear of each projecting lens is a double convex condensing lens and a prism or mirror or its equivalent for retracting or, reflecting the light so that the axis of the cone of light is in the line passingthroughthe centres of each condensing lens and its corresponding projecting lens. In front of each projecting-lens is a means for varying the luminos:
ity preferably an iris diaphragm and also supports for' colour screens, The positives -t0'be projected are placednear the double convexlenses and preferably between the latter and the projecting lenses. In place of providing a. mirror for each lens, one mirror.
common to all the lenses (may be employed.
A- double concave or piano concave lens vmay be arranged in front of the projecting lenses for refractin the light in order to increase the size of tli with the distance to which the'picture is to be rojected. 7 he same apparatus may be used for taking the negatives in which case the photographic plate is placed in rear of the projecting'lenses,
A camera suitable for use in this process consists of a photographic plate holder having a circular opening which is'covered by a light-tight disk, the plate holder being rotatably mounted on -a pivot on the disk. On the disk is an eccentric boss rotatably mounted in a bracket and containing a positive lens. The plate holder is attached to e design simultaneously the bracket by two pivoted links to allow it to move when the disk is turned. The distance between the centre of the disk and the axis .ofthe lens depends ion the size of the hotographic plates 'used in the camera and. .m the projector, that is the magnification;
The distance between the centre of the boss and the axis vof the lens depends on the rela tive size of the model scene and the theatre.
positions in a circle so that a number oi positive photographs of part ofthe scene can be taken upon the plate, and on the disk are a number of notches corresponding to the positions of the lens and a catch is provided which enters the notches and holds the disk stationary while the photograph is being taken.
The bracket may beslidably mounted upon a graduated upright and may also be mounted so that it can be turned to tilt the plate, a scale being provided to indicate the angle through which the bracket has been which caps are used when-the instrument turned.
The accompanying drawings illustrate a projector which may be employed as a camera and also a camera both of which are suitable for use in carrying out the invention.
Figure 1 is a longitudinal section partly in elevation, Figure 2 is a front elevation and Figure 3 is a view on the line 3, 3, Fig ure 1, looking in the direction of the arrows, of a projector which may be employed as a camera. Figures 4 and 5 are a side and a front elevation of a modification. Figure 6 is a front elevation of a camera and Figure 7 is a vertical section while Figure 8 is a diagrammatic view of a plate.
Referring to Figures 1, 2 and 3, 10 is a source of light and 11 are prisms, supported in a frame 12, which refract the light so that it passes through condensing lenses 13 and projecting lenses 14, the path of the light being such that the axisof each cone of light passes through the centres of each condensing lens 13 and its corresponding projecting lens 14. Between the source of light and the prisms 11 is a sheet 15 of glass or other heat insulating material. Arranged in front of each projecting lens 14 is an iris diaphra m 16 of usual construction and a holder 1? for retaining. a colour screen 171, the amount of luminosity being varied by the iris diaphragms and the colours by the colour screens. A plate 18 on which the positives are taken is retainedv in rear of the projecting lenses 14 in a holder 181.
In the modification shown in Figures 4; and 5 a plano concave lens 19 is mounted in a frame 20 supported by a socket 21 on a rod 22 secured to the end of the instrument. On the, socket 21 is a pivoted catch 210 which when in the position shown in the drawings enters a slot in the rod 22 and S0 holds the lens 19 in position. A second rod 23 is provided upon which a projection 200 on the frame 20 rests. The light issuing from the,projeotinglenses is refracted by the lens 19 in order to increase the size of the design simultaneously with the distance to which the picture is to be projected. I i In Figure 4 the holders 17 with the-exception of one are shown provided with caps 24 is em loyed 'as' a camera.
Re erring to Figures 6, 7 and 8 which show a camera, 25 is a plate holder having 7 circular openings 250 which is covered by a light-tight disk 26, the plate holder being rotatably mounted on a pivot 27 on the disk 26 and a ring 261 on the disk 26 extends into a groove in the plate holder 25. On the disk 26 is an eccentric boss 28 rotatably mounted in a bracket 29 and in the boss is a positive lens 30. The plate holder 25 is attached to the bracket 29 by two links 31 which allow it to move. lVhen the disk is turned the lens 30 will successively take up a number of positions in a circle on a hotographic plate 32 mounted in the plate ioldcr 25. The photographic plate and the positions of the photographs taken by the lens are dia rammatically shown in Figure 8. In-the isk 26 is a number of notches 260 corresponding to the positions of the lens 30 and a catch 33 is provided on the plate the angle through which the part of the bracket carrying the plate holder is turned.
