PIN-HOLE PHOTOGRAPHY FOE DENTAL APPLIANCES OR CASES. BY W. A. HECKARD, D. D. S., NEW YOKE. Jn these few remarks I wish to make two points:—One, Pin Hole Photography—the other to show how one canmake the orthodontia appliances, pictured here, easily and simply. Fig. 1 was my first photograph of this series of but Fig. 10 were made with a pin hole in a Brownie $ cam-era. Number 10 is a cut I have had on my desk some time and Icannot just now recall to whom to give credit; however, as the samething is shown in Angles book as well as in other places, we willlet it pass. The Pin Hole Camera. T was thinking of my boyhood days. when the idea struck me to try it. I pushed a thin disk of Germansilver behind the shutter, having poked out the lens to get at it. Anysubstance that will shut out light will do instead of the Germansilver—I happened to have that. I made the hole, and the tiniestone, with a very sharp pointed round excavator, rotating it betweenmy fingers until it barely penetrated. The hole should be round andthe smallest it is possible to make. It takes a longer exposure, butyou get sharper pictures. Expose for from six minutes in the sunat ten, eleven oclock or mid-day, to half an hour to an hour and ahalf along about three-thirty or four oclock. It is in focus at alldistances. An object that will go on the film, will be reproduced atits exact size if just as far away from the pin hole as the film i^from the pin hole. Closer to the pin hole than the film, and yourphotograph will be larger than the actual size, and farther from thepin hole t
