Text Appearing Before Image:
oscopic picture is desired as manyphotographs as will be required by thearrangement which has been chosen, andeach photograph from a different point ofview or at a different phase of motion. Suppose you have made the arrange-ment for nine pictures, how are these pro-duced in the quickest and most convenientmanner ? In the case of rapid or veryshort motions, as, for instance, strikingwith a hammer, blinking with the eyes,opening the mouth, drinking, &c., onlytwo or three photographs are necessary,but from each negative respectively three,four, or five prints are to be taken. Theseprints are then mounted on a pasteboarddisc (the size of which depends on thesize and on the number of the pictures),so that the different pictures are arrangedalternately thus: i, 2, i, 2, i, 2, &c.(see fig. 52). With this arrangement thepictures will show rapid motions ; theymay be rendered slower by arranging 146 PHOTOGRAPHIC PASTIMES. them thus: i, i, 2, 2, i, i, 2, 2 ; or i, i,I, 2, 2, 2, 3, 3, 3.

Fig. 52.—Arrangement of the Stroboscopic Pictures. As regards mounting the prints, thisis a somewhat difficult operation. Theparts of each picture which are to main-tain the condition of the eyes should be STROBOSCOPIC PICTURES. 147 arranged at equal distances from eachother and from the axis of the turningpoint. To render this possible, smalldiscs of cardboard of the required sizesshould be cut and provided with thefollowing division: the radius of the circleis divided into nine parts of equal size,and from these points of division lines aredrawn to the centre of the circle. Thepictures are then mounted, so that eachtime their height exactly ends with theedge of the disc ; it is well to measureafterwards with a pair of compasses, inorder to ascertain that the different pic-tures are arranged at equal distances fromthe centre of the disc. Then the centreof each picture must be mounted exactlyon one of the lines by which the circle isdivided into nine parts. Unless theserules are obs
