REPORT OF THE PROGRESS COMMITTEE— MAY 1929 ONE of the outstanding features of progress during the past six months is the fact that producers and exhibitors have finally realized that the exhibition value of the motion picture is now dependent in no small way on the efforts of the engineer. The industry has gone technical and with the advent of a large number of engineers into the Society from the electrical, radio, and acoustical professions, progress is proceeding at a rapid pace. The sound motion picture and especially the "talkie" has almost entirely replaced the silent motion picture and there is no reason to believe that the talkie will ever be usurped in favor of the silent picture. The quality of the sound reproduction presented in the average theatre leaves much to be desired, but the improvement in quality effected during the past six months has been remarkable. Progress in studio technic includes more extensive use of voice doubling, extension of the length of the transmission line between the microphone and the recorder, and the use of more noiseless cameras which do not require the use of a sound proof enclosure. At the present time most of the studios are recording on film and supplying both sound on film and wax records for the theatre. Sound motion pictures are also now available for the amateur in connection with 16 mm. film, the sound reproduction being from wax records. Producers and exhibitors are now more appreciative of the entertainment value of color in sound motion pictures, especially those of the musical comedy type and several features have appeared with extensive color inserts, one picture of feature length having been produced entirely in color. Most of the color films have been produced by the two-color subtractive method, the dye images being obtained by the imbibition of two dyes into a single gelatin film. The outstanding advance in color photography was the perfection of the Keller-Dorian process for 16 mm. film which is being marketed under the trade name of ''Kodacolor." This process is not yet available for 35 mm. film. 66
