A PARALLEL OF TECHNICAL VALUES BETWEEN 35 AND 16 MILLIMETER FILMS
J. A. Dubray and R. F. Mitchell*
WHEN first introduced, 16-mm film was essentially confined to amateur cinematography. However, the last few years have shown an interesting and constant increase of the use of 16 millimeter film in more academic work than that usually done by amateurs.
The Industrial. Scientific and Educational fields have become aware of the opportunities that 16 millimeter films offer for producing and exhibiting at a moderate cost, motion pictures of a quality which favorably compare with the 35 millimeter professional standard.
Industrial organizations use 16 millimeter films for keeping records of manufacturing processes, for instructing their employees on established manufacturing, packing, shipping, safety processes and measures adopted within the organization, and for broadcasting to the buyer or the public at large, the characteristics and qualities of the product they manufacture.
In the scientific world, 16 millimeter films have proven invaluable to the laboratory researcher, and have found a prominent place in the surgical and medical clinics.
1 6 millimeter films have entered the classroom, the large as well as the small auditoriums, and their use is rapidly increasing and receiving official sanction.
These phases of practical usefulness of motion pictures have been making extremely rapid strides and 16 millimeter films are often preferred to the professional 35 millimeter, for economic as well as technical reasons.
It happens, however, quite often that a prospective user of motion pictures, or even one perfectly conversant with 35 millimeter films, is quite in doubt as to which type of film he should use for a particular purpose, and the question which is perhaps most often asked by semi-professional cinematographers is "When and why should I use 35 millimeter films in preference to 16 millimeter and vice versa".
We will attempt to answer this question with special reference to simple technical considerations in preference to the economical factor involved and which is obviously in favor of 16 millimeter with regard to both equipment and operating costs.
In order to logically follow the various factors involved in the matter, we will consider, under different headings, the methods of handling the various operating phases which contribute to make a finished motion picture:
Equipment
Perfection of design and manufacture of machinery and equipment constructed for handling motion picture films is of prime importance irrespective of the type and size of the film itself.
