The Art of projection and complete magic lantern ... - Yesterday Image

t58both mechanism and designs have been very much improved. There issome six to eight designs of figures, in various attitudes, on each sHde,which is about ten inches long, but in the Giant Choreutoscope is twentyinches. This long slide is made to pass behind an opening in the frameand during the interval of the change between each figure a shuttercovers the opening until the next following design is in its place, when itagain opens ; the interval between each change is worked ad lib. Someof the designs are brought out to their best advantage when shown inconjunction with some set scene, or set of effects, for instance the dancingskeleton indulging in his wild terpsichorean revel in the bedroomscene of the haunted castle, is most weird. The Harlequin and Columbinedance are seen at their best on a dark back-ground, or an appropriateharlequinade scene.The Performing Monkeys are very interesting slides, and to thejuvenile portion of an audience especially, as they tumble about into themost grotesque attitudes, as each monkey is jointed in some six placesFig 79.of his body. A very pretty effect is made by tinting up the back-groundwith different tints of colour by the aid of gelatine^or coloured glass heldin front of the lantern.The Snow Storm.—The original snow effect was produced bypicking out minute specks upon a length of glass painted black, drawnthrough the lantern upwards from the bottom, the snow represented bythe light passing through the pricked out specks appears to fall. At thepresent time the slide consists of two rollers at top and bottom, a lengthof black material pricked with a hot needle is made to roll from oneroller to the other, in commencing all the material is on the bottomroller and is wound off to produce the falling of snow on to the top(being inverted), care must be taken not to have the holes too large, orthe snow flakes will appear very much exaggerated, it is also as well inworking to have the holes slightly out of focus.This effect may be used
