Educational film catalog (1936)

767-780 EDUCATIONAL tFILM CATALOG Modem lithographer— Continued maJcer photographs a proof plate on sensi- tized metal, from each negative. When proofs of these test plates have been printed over each other, a check is made by a supervising craftsman to assure au- thentic reproduction. Xow another plate-making operator brings in a large sensitized plate on which he makes multiple prints. Modern mass production is evident in a huge photo- offset press room. Thus, a million recipe booklets, effectively presenting their mes- sages to a million housewives emerge. A few suggestions of varied uses follow— using fruit, ham, cattle, elevated trans- portation, service station business, Santa and a ship "Describes in detail the techniques of lithographic artists and the processes of duplicating black and white and color orig- inals by means of direct and photo-offset lithography. The roles of the commercial photographer and the modern printing press in the mass production of attractive art prints, including advertising materials, are portrayed. The relation of commercial art to problems of present-day living is indi- cated. The film thus depicts adaptations of creative art to requirements of the machine age. It is thought-challenging from the points of view of the artist, the technician, and the social observer alike." Georgia Film may be used in the elementary social studies, in industrial arts and voca- tional guidance programs and in home economics and art instruction Jh-sh-c-trade-adult Guide 767 Etching Make an etching.

Shots of his curious box-like cameras follow. Mr Talbot is seen taking pictures and a number of early negatives are shown. From these early beginnings came the films of today, born as an edited feature in 1889. Mr Thomas Armat sitting in a garden chair tells of his interest and work and .shows some of his early crude apparatus for projecting. He tells of his efforts to secure film, in- cluding at some length an account of his contacts with Mr Edison's office and final arrangements for production of projection machines by Mr Edison sh Elements of photography. 22min 16-si- $42; rent $3 1940 Gutlohn 770 ALSO AVAILABLE FROM 16mm: B&H Ohio "The film is in two parts. The first shows the taking of the picture. . . Method of loading and unloading of plate- holders is shown. Then follow the mix- ing of chemicals, and actual development (in tank) and fixing of film image. The demonstration is shown under conditions impossible except to very small groups under actual dark-room conditions. Part II deals with the making of a print, showing all steps in detail, from mixing of chemicals, through choice of paper and projection of image under en- larger, to development and fixing of print. The method of washing is also shown. The photography and interest are ex- cellent. Usefulness is probably limited to camera clubs, but is very good for this purpose, particularly for large groups, where darkroom demonstrations would be difficult or impossible." Committee on classroom films "Film appears to be a little old. Pho- tography is not clear. A good explana- tion of the various parts of the camera." California "Effective training film." A. A.

A series of high speed motion pictures taken with stroboscopic light, show such scenes as: formation and splashing of milk drops, flow of water from a jug, breaking of cups on the floor, human muscles in action, and humming-birds in flight."

The commentator, with the aid of diagrams, explains the photographic process. Diagrammatic drawings of silver- bromide crystals are shown and we are told of the chemical reaction that occurs when light falls upon them. There are experiments illustrating what occurs when the crystals are given exposures of dif- ferent intensities and how they receive and store the latent image. The following sequence deals with the different chemi- cals used in the formation of the de- veloper, and the fixing bath. A compari- son is drawn between the 'dark room' operations of the old days and the new, modernly equipped laboratories. The film closes showing a positive print being made from a negative. An excellent film on chemistry and physics. Commentary is good and the film is beautifully photographed. May well be used in college and high school classes."
