Technical Questions and Answers stripe applicator in the Hollywood area? — R. C. D., Southgate, Calif. A.— Question 1 : The projector men¬ tioned is made in England. Sound stripe specifications are the same for this machine as for the U.S.-made model. Q. / have access to an Auricon sound-onfilm camera and am wonder¬ ing if 1 could use it in a double-system setup. If I shoot picture and sound with this earner (i in normal manner, the film l get back from the lab has the picture and sound track combined and, of course, this presents a problem in edit¬ ing. Now, can / have the lab make a print of the film and also a second print of the optical track only, so thfit the two can be handled in editing in the conventional manner ? W ill quality of the sound track be degraded if trans¬ ferred from the original film to mag¬ netic film? — D. S. Endicott, N. Y. A. \ou do not state if you plan to record the sound on film with the ob¬ ject of separating it later for editing purposes, or if the sound is to be re¬ corded separately on tape in sync with the camera film. In either case, the lab procedure stated will prove satisfac¬ tory. When sending your film to the laboratory, accompany it with detailed instructions as to your reqiurements re¬ garding separation of sound track and film. The process of electro -printing, which most major labs offer, will ren¬ der a satisfactory magnetic track from your optical original. Q. I have four questions regarding magnetic sound stripe: 1) Is there any particular specifica¬ tion required for soundstripe on 16mm film as used with a Bell & Howell Model 602-C projector? 2) Can a satisfactory stripe be ap¬ plied to double-perforated 16mm film? Can it be applied to intercut single and double perforated film? 3) Please name a competent sound Question 2: Only a quarter-track (25 mils wide) will be satisfactory for intercut single and double-perf film. If the track is any wider, it will overlap the perforations of the doubleperf sections of your film, causing dis¬ tortion in the sound for these segments. Question 3: Yes. Question 4: The Vitatone Co., 7361/2 So. Atlantic Blvd., Los Angeles 22, Calif.; also, Color Reproduction Co., 7936 Santa Monica Blvd., Hollywood 38, Calif. Q, Will an exposure meter reading of daylight for black-and-white film also apply to color film? For example, if the meter reading for black-andwhite film with an ASA rating ( day¬ light) of 50 is f/16 at 1/400 sec. ex¬ posure, will the same rating also apply Continued on Page 520 ACMADE MARK • 35mm and 16mm • For Studios & TV • Cutting and Viewing MAKES EDITING EASY! ’• Continuous movement (nonintermittent) safer for negative or positive viewing. • Synchronous and variable speed, instant stop, forward and reverse foot pedals and press button. • Film paths instantly declutchable by switch selection. • Projected picture 8"x6" or larger by removing screen. • Separate magnetic and combined optical and magnetic heads. • Built-in synchronizer footage counter and running time counter. • Removable flange plate with tite wind roller. • Instant sound track selector. • Manual inching control. • Fast rewind controls. | AMONG THE USERS: 1 American Meteorological Society, Mass.
