Show A Pasteboard Camera. . The enthusiastic student of photography photog-raphy may obtain a good deal of amusement, amuse-ment, and not a little knowledge, by experiment ex-periment with the "pasteboard camera," as it has been called. Take a long cigar box and blacken the inside. Make a pin hole in the centre of one of the ends, and place a sheet of carbonic paper beneath the lid and jam it down. If a 4 by 5 dry plate is placed at the end opposite the pin hole, with the sensitive aide toward the latter, the lid jammed down and the box taken from the dark room to an open window, where there is a view of some building or other object, a very fair picture pict-ure will be obtained on returning the box to the dark room and developing the plate at the end of half an hour'a expos-! expos-! ure. By interposing a meniscus lens the ' aperture of the pin hole may be greatly enlarged, and the taking of the picture much quickened. New York Evening Sun. ' ' |
