Show HOW TO MAKE LANTERN SLIDES. Tho popularity ot lantern slides, and especially of tho -colored ones, as a means of Illustrating songs, has caused so large a demand for this class of work thnt almost any amateur may tako up slide-making nt n good profit. Tho lantern slldu Is a glass plate, coated with slow and extremely flno grained emulsion. Tho slzo Is 3Vix Inches. A lantern slldo Is merely a print on n glass plate Instead of on paper. Lantern slides enn bo mado In two different ways, Ono Is by contact, exactly the samo as a print Is mndo on paper, and tho other by reduction In tho camera. In making slides by contact, con-tact, solcct tho ncgatlvo and placo It In tho printing frame and put the Ian. tern plato upon It, film to film, Clamp down tho back and oxposo tho samo as for making a print. A good method tor exposing Is to hold a lighted match nbout three Inches from tho frame for three or moro seconds according to tho density. Development Is carried on tho samo as with a negative Tho Imago should appear In about a minute, and dovol-opmcnt dovol-opmcnt should be over In thrco or four minutes. If tho exposure has boon correct, cor-rect, the high lights will stay white throughout tho development and will como out clear glass after fixing. It Is best to iibo the dovclopors recommended recom-mended by tho manufacturer of tho plates you aro using and you will find tho formula In each package ot plates. It Is best, to uso a plain fixing bath, which musMio fresh and kept as cool as possible in hot woather. f Whon. tho nugatlvo Is larger than tho lantern slldo plate, and It Is do-slrnblo do-slrnblo to.j-educo tho entire view upon tho slide, a llttlo extra work will bo necessary. Select a room with ono window, If possible, and fit a light-proof light-proof framo Into It to keop out ull light with tho exception of a hole In -H which to place tho negative as shown In Fig. 1, Unless this hole Is on a lino with tho sky It will bo necessary to place n largo sheet ot whlto cardboard 'H at an nnglo of 45 degrees on tho out- H sldo ot tho framo to reflect tho light 'H through tho ncgatlvo as shown In Fig. 2. Make or sccuro nn lnsldo kit to placo In tho plato holder of your camera to hold tho lantern slldo plato as shown In Fig. 3. Draw lines With a pencil, outlining on the ground glass of tho camera tho slzo ot tho lantern slldo plato, and In tho placo whero the 'H plato will bo In tho plato holder when placed In position In tho camera. This 'H r- - -i , , j SSB will cnnblo yon lo focus to tho proper size. Placo tho camera In front ot 'H the holo In the frame, placo tho nega tlvo In tho holo and focus tho camera ,H for tho lantern slide slzo. Expose with -H a medium stop for about 20 seconds 'H and treat tho plate tho samo as with tho contact exposure. 'H Whon dry, says Popular Mechanics, J the lantorn slldo plato inny bo tinted any color by means of liquid colors; ' ,H Theso can bo purchased from any jl photo material storo, In coloring the slldo plato It Is only necessary to moisten tho gelatine- film from time to HLH tlmo with a pleco ot cloth dampened. In wator, Tho colors may then be spread evenly with a soft brush, which 'H should bo kept In motion to prevent T Tho slldo Is put together by placing a mat of black paper, as Bhown In Fig. iH A, an tho gelatine sldo of tho litntern iH slldo, A, Fig. S, and then a plain glass, ''H I), over the mat, O, and tho throo bound together with pasio-partout tape, D, Contrnsty negatives malio tho best ' jH slides, but tho lantern slide plato should bo mado without any attempt JH to gain donttty. ll JCiPBsS |
